Hi, 4990 packages to upgrade, 3 to downgrade, 26 new, 1 to reinstall, 9 to remove. Overall download size: 3.94 GiB. Already cached: 7.18 GiB. Download only. Fun, but why does the cached size outdo the overall size? Cheers, Pete

As Michael noted, I keep the caches on purpose, and share /var/cache/zypp/ packages with other machines, but those numbers are a bit different as well: ~> du -sh /var/cache/zypp/packages/ 199G /var/cache/zypp/packages/ Reveals the question, if libzypp takes available, but unrelated packages into account?

Wow, you must be keeping a lot of packages. I did a purge this morning and my zypp cache dropped from 10G to 4.5G. I basically do an rpm -q -a and then remove cache files not in that list. I've put a gist on github: https://gist.github.com/digitaltrails/cfd6617be9f0e5cfbdaaf951d4526aef The downside of purging off old rpm's is that I can no longer revert to older versions via the cache. For me that's not a problem, I only want an up to date cache for seeding another desktop. Cheers, Michael

The rpm's in the cache are not kept by default. If it they are kept, zypper does not purge any, so many versions of each rpm may pile up. This can be useful if you need to revert to an earlier version of an rpm or wish to seed the cache of other machines. I use the cache from one machine to seed the nearly identical machine, but rather than copying over old disused rpm's I may run a home made script to do a purge first. I can post the script if anyone's interested. Cheers, Michael

Have you tried apt-cacher-ng for that? It works not only for apt on debian, but also for zypper. I'm using it in a mixed environment of Debian/Raspbian and oS machines (real and virtual) and it a) means that the machines in question don't need direct internet access - only the VM running apt-cagher-ng does; and b) it saves a heap on internet bandwidth and dramatically speeds up updates for all but the first machine requesting a particular set of updates. Very simple to setup, too. Debian (and Debian-derivative) clients using apt are extremely easy to setup - zypper needs a little more work, with manual editing of the repo URL's for each repo that needs caching, but that only needs to be done once, when a repo is added (or it is deployed for the first time). Hopefully someone might find this useful. -- ============================================================== Rodney Baker VK5ZTV rodney.baker@iinet.net.au CCNA #CSCO12880208 ==============================================================

No - at home I'm running it on Tumbleweed. If it's not in the main repo, someone has built it in an OBS repo. Can't remember exactly - I'd have to check Yast2.

I can see that being useful if you have a large number of machines with different software installed. I had in the past wondered about using squid to do some mirroring of repos, but the need hasn't eventuated. In my case I have two desktops and they're deliberately kept quite similar. I don't need to mirror everthing in the repos, just the 3-4GB required for those two machines. Cheers, Michael

That's exactly the point of apt-cacher-ng - it acts as a local proxy server for apt/zypper/yum, rather than a full mirror. It only grabs what's requested. If a package it not in the cache, it grabs it and caches it. The next request for that package is served from the local cache. For example, at work I have 2 TW laptops, with about 90% commonality between them. The first one that updates takes a while, because all packages are downloaded from the net. The next one gets almost everything from the local cache, so it's download takes a fraction of the time because it's happening at LAN speed. Same at home with my Raspberry Pi's - the first one that updates ensures that the cache is populated with the latest packages - the rest grab those packages from the cache, which is running on my TW desktop (because it has the most storage). It also has a way of expiring superseded packages so that the cache size doesn't grow out of control (naturally). That can be turned off if needed.
