[opensuse] Leap 15.0: updates missing from repository?
Just after 1700 UTC today, 15 updates for 15.0 were posted into the updates mailing list. So far, 6 hours later, they have yet to appear on the repository. Most of them are labelled "moderate", but a couple are "important". The first one is for google-compute-engine, the last for yast2-storage-ng -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

Depending from what mirror server you use (or that the automatic opensuse mechanism attributes to you), you may experience a more or less important delay between announcement and availability. If you wish to enhance this, you may (but of course with the drawback of getting "dependent" on one mirror server), choose and alter manually to a specific server with a good update policy. You can choose them (for your specific location) when going to "leap" install, then you see below the option "choose mirror"- you choose the one you like most, you copy the address and cut the the part of the root (in order to get to opensuse). I suppose you know perfectly how to do this and that I am going to annoy you but for the sake of it: e.g. http://mirror.de.leaseweb.net/opensuse/distribution/leap/15.0/iso/openSUSE-L... So you cut out "iso/openSUSE-Leap-15.0-DVD-x86_64.iso" and are left with the link: http://mirror.de.leaseweb.net/opensuse/distribution/leap/15.0/ If you want to give it a try, the main part of them supports https, so: https://mirror.de.leaseweb.net/opensuse/distribution/leap/15.0/ (all this for my location. I expect you to have a totally other list for your location). Forgive me if this appears to be patronizing or "bike-shedding".

No problem; others may find it useful. I've never found any need to use one of the mirrors, the master repositories on opensuse.org have always worked fine for me. I had assumed that updates would be available there almost as soon as they appear on the mailing list -- at least, that has always been my experience thus far. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

iiuc, you are almost *always* using a mirror rather than the *master* repository. it just is not advertised. -- (paka)Patrick Shanahan Plainfield, Indiana, USA @ptilopteri http://en.opensuse.org openSUSE Community Member facebook/ptilopteri Registered Linux User #207535 @ http://linuxcounter.net Photos: http://wahoo.no-ip.org/piwigo paka @ IRCnet freenode -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

... And even so, the mirror you get may vary according to matters not under your control. I have a nominal 75Mb/s link. At times I can download from the repositories at about 65MB/s, which, considering overheads, file access, process and network, I consider very good. At other times I'm luck to get 2.5Mb/s Sometimes I wonder id all those people thinking that setting up a CRON job for 4am aren't tripping up over each other and that about 7:30 while many are on the way to work isn't a better time. I wonder what the algorithm for selecting a mirror is? It obviously isn't as simple as 'electronically nearest'/'fewest hops'.

I think there must be something, because when I 'peek behind the curtain' I see different mirrors being used sometimes when I 'zypper up'. -- A: Yes. > Q: Are you sure? >> A: Because it reverses the logical flow of conversation. >>> Q: Why is top posting frowned upon? -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

Hmmm. Whatever algorithm it uses to determine that, then, is quite faulty. In Canada, here, mirrorbrain pushes me to a Very Sluggish Mirror way across on the other side of the continent (I am in BC, it wants me to load from Far Eastern Canada) which seems to be additionally hampered by choked routing through Large Canadian Telcos and Cable Companies (in almost Monopolistic situations). This, when simply due south in the U.S.A., only a relatively few kilometres away, is a very fast mirror. I have to manually override mirrorbrain in order to download the DVD installers, and also manually override mirrorbrain in order to be able to run zypper up or zypper dup and have it conclude without crashing or without waiting a half a week for it to finish. -- -Gerry Makaro openSUSE Member openSUSE Forum Moderator openSUSE Contributor aka Fraser_Bell on the Forums, OBS, IRC, and mail at openSUSE.org Fraser-Bell on Github -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

Send a detailed description to admin@o.o and I'll have a look.

Yes, that is very true. It is not about geographical promixity, but about network ditto.

That one isn't listed as an openSUSE mirror :-) In Toulouse we have CICT, but it is inactive.

Thanks for your reply, Per. Actually, the problem is that Mirrorbrain, in our implementation, looks for a Mirror within the same country first, and chooses the "fastest" one of those. That algorithm, of course, works just fine on your continent, since most of the countries there are a mere fraction the size of my own Province, much less my Country. However, in North America, that is a "faulty" method, IMHO. Not sure if that can be addressed easily in Mirrorbrain. What I would like to see is an easy "simple click" method in Yast to pick a closer mirror or an alternate mirror when the default chosen mirror has a problem or is otherwise unsuitable. I would also love to see an additional easy flag or config in zypper to allow choice of another mirror if the Mirrorbrain-chosen mirror is not working well. My current method is to manually test mirrors, then hard-code the "best" mirror in my repos list. That works just fine, but is a little more convoluted and is not an easy thing for Linux or openSUSE newcomers to use. -- -Gerry Makaro openSUSE Member openSUSE Forum Moderator openSUSE Contributor aka Fraser_Bell on the Forums, OBS, IRC, and mail at openSUSE.org Fraser-Bell on Github -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

An option in zypper and/or in Yast might be able to temporarily (or even permanantly) "hard-code" a preferred mirror in a User's repo list, or some such similar thing.

Patrick posted a method I saw later, and which works now, whereas my idea would need to be coded.

However, I understand it goes to the next one only if the previous fails completely - and an slow link is a working one.

It is done with segmented downloading, really just plain http. "get me a bit of this file, from x to y". I looked at this years back, because I was having trouble getting squid to cache the repos.

It was done in parallel some years ago, because YaST could optionally (or by default?) use aria. Currently I think an internal downloader is use.

Whatever algorithm it uses to determine that, then, is quite faulty.
I doubt it, but it is open source software, you can have a look:
In Canada, here, mirrorbrain pushes me to a Very Sluggish Mirror way across on the other side of the continent (I am in BC, it wants me to load from Far Eastern Canada) which seems to be additionally hampered by choked routing through Large Canadian Telcos and Cable Companies (in almost Monopolistic situations).
This, when simply due south in the U.S.A., only a relatively few kilometres away, is a very fast mirror.
Send a detailed description to admin@o.o and I'll have a look. It might be that the fast mirror in the US does not want non-US traffic, for instance.
Thanks for your reply, Per.
Actually, the problem is that Mirrorbrain, in our implementation, looks for a Mirror within the same country first, and chooses the "fastest" one of those.
That algorithm, of course, works just fine on your continent, since most of the countries there are a mere fraction the size of my own Province, much less my Country.
However, in North America, that is a "faulty" method, IMHO.
Not sure if that can be addressed easily in Mirrorbrain.
What I would like to see is an easy "simple click" method in Yast to pick a closer mirror or an alternate mirror when the default chosen mirror has a problem or is otherwise unsuitable.
I would also love to see an additional easy flag or config in zypper to allow choice of another mirror if the Mirrorbrain-chosen mirror is not working well.
My current method is to manually test mirrors, then hard-code the "best" mirror in my repos list.
That works just fine, but is a little more convoluted and is not an easy thing for Linux or openSUSE newcomers to use.
it is possible to accomplish by listing more than one site in your repo's. ie: [Tumbleweed.OSS] name=openSUSE-Tumbleweed OSS enabled=1 autorefresh=0 baseurl=http://download.opensuse.org/tumbleweed/repo/oss/ http://ftp.ussg.iu.edu/linux/opensuse/tumbleweed/repo/oss/ http://distro.ibiblio.org/opensuse/tumbleweed/repo/oss/ http://suse.mobile-central.org/tumbleweed/repo/oss/ http://ftp.uni-erlangen.de/opensuse/tumbleweed/repo/non-oss/ http://ftp5.gwdg.de/pub/opensuse/tumbleweed/repo/oss/ type=rpm-md sort the basurl's to put the fastest first and decending. iiuc, they will be accessed first to last until one connects. -- (paka)Patrick Shanahan Plainfield, Indiana, USA @ptilopteri http://en.opensuse.org openSUSE Community Member facebook/ptilopteri Registered Linux User #207535 @ http://linuxcounter.net Photos: http://wahoo.no-ip.org/piwigo paka @ IRCnet freenode -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

Probably not, but it is also a matter of not enough mirrors. Canada has just three mirrors - in Toronto, Halifax and Winnipeg.

Now, this is a curious thing. My ISP gives me 300 Mb/s, and is going to improve to 600. At this speed, it becomes possible for home users to become mirrors - except that of course, they are dynamic IPs and the ISP might not like it. But I look at the Windows competition, and Windows 10 has a feature which is users becoming p2p-type update suppliers, for the local network or for Internet. The user can opt-out, but in theory it is an interesting idea. Our rpms are PGP signed, so security is ensured. If some summer project reuses some existing p2p protocol or invents a new one so that openSUSE users can become also "servers" of rpms, it could be a nice idea. Torrent, emule, I don't know. It would require some seeder or directory service. No, it is beyond my knowledge to give more details about that idea :-) -- Cheers / Saludos, Carlos E. R.

The dynamic IP could be taken of with dynamic DNS, and your mirror could be given a reduced priority. OTOH, if you were to run a mirror in Spain, it would be running red-hot very soon.

I've never found any need to use one of the mirrors, the master repositories on opensuse.org have always worked fine for me.
I had assumed that updates would be available there almost as soon as they appear on the mailing list -- at least, that has always been my experience thus far.
iiuc, you are almost *always* using a mirror rather than the *master* repository. it just is not advertised.

Much depends on mirrors available in or near your location. And your own downstream link of course. A kernel is about 50Mb, for me it takes just over a second, from a local Swiss server.

You probably already know this but when last time I used Ubuntu, before downloading file, it would ping various sites and choose the one which had the fastest ping result. Of course, you had the ability to override this selection and choose (from a list) your own site for the download. I assume that zypper or Yast doesn't have this feature?

Yes, indeed. I do not make the change very often, usually only once. I test to see if the mirror feeds the download at a decent speed. If it does a great job, I choose that mirror, then hard-code it into my repos.

Quick ping time doesn't mean much, unless it is very slow to respond. The bandwidth is very important.
Oh yes, how well it can keep the pipeline filled and how fast you can consume it. As I said ... I'm paying for a channel many times faster than the best perceived download speed I have experienced based on letting mirrorbrain select a site for me. While a 'ping' may tell you the electronic distance and the modified sort of ping that is 'traceroute' you are quite right, Carlos, neither tells you about bandwidth. It may be that a site in Israel give me, here in Canada, the best bandwidth and the times I carry out my downloads of updates. So, does mirrorbrain somehow figure out bandwidths? I'd love to know how! There are many mirror sites. While pinging then to find 'distance' may be tedious, it could be automated. And yes we know that electrical distance and physical distance are not necessarily related. But other than just hitting on one well performing site as Fraser_bell describes is, well ... those of who know optimization theory recognise that this may just be a local maxima and there are 'higher peaks' out there. But how to find them? even if, as Fraser_Bell mentions, I let mirrorbrain select and note the local optima, I still don't now why it selected that site at that time and another poorly performing site at another time. -- A: Yes. > Q: Are you sure? >> A: Because it reverses the logical flow of conversation. >>> Q: Why is top posting frowned upon? -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

oh, just done a update on a "quiet sunday" Retrieving: kernel-macros-4.17.0-2.1.xxx.noarch.rpm ....[done (407.8 KiB/s)] Well Foo to that performance too.
It looks like that came from
http://ftp2.nluug.nl/os/Linux/distr/opensuse/repositories/Kernel:/stable/sta...
according to the log file.
Just an observation - this is from repositories/, which many sites don't mirror.
Something sucks at mirrorbrain. Like bricks though a straw.
Send detailed information to admin@o.o and I'll be happy to look into it. -- Per Jessen, Zürich (20.2°C) member, openSUSE Heroes -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

Anton, there are no mirrors for repositoriss/ in Canada, and exactly one mirror for repositories/ in the US - in Provo, Utah. The top-ten countries for repositories/ for you : UK, the Netherlands, Germany, Czech Republic, Poland, Russia, Armenia. -- Per Jessen, Zürich (21.1°C) member, openSUSE Heroes. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
