[opensuse] zypper and a couple RPMs

I have a strange issue with zypper and RPMS from OBS. At first I thought it was related to the aarch64 repos I was using. Now I see the same files have problems on other openSUSE versions when zypper is trying to retrieve them. What happens is that most all of the file is downloaded. But the download status stays at 99% for a bit, and then zypper fails and wants to to retry the download. It never succeeds. It is always the same files that fail from different zypper clients: http://download.opensuse.org/tumbleweed/repo/oss/suse/noarch/kernel-firmware... http://download.opensuse.org/tumbleweed/repo/oss/suse/noarch/php5-ZendFramew... So, I downloaded them in my browser (on the same computer where zypper is failing) and that works. The files are probably okay. So, I thought I would put the files in /var/cache/zypp/packages/repo-oss/suse/noarch so the files would not need to be retrieved again. All the other files waiting to be installed are there, and zypper does not try to get those again. Seems just adding these files here does not make zypper see them. I guess that's too easy. It tries to retrieve them again. Is there any way to get zypper to use these files instead of trying to download them again? In one case I am doing a zypper dup from 13.1 to Tumbleweed. So there are thousands of files involved. Getting the dup to ignore needing these files seems like it would cause other issues.

I've seen this too, on multiple non-TW boxes, but with different rpms. It makes installs/upgrades real ordeals. I've noticed that after zypper stalls at 99% for a while, a single ^C will back it out to an abort/retry dialog. Selecting "retry" at this point will frequently allow zypper to complete. But not always. I've seen updates after fresh installs take hours because of this issue, which started about one-month ago. I've been thinking it's something in the network security stack where I'm working, but if others are seeing it? I'll take notes the next time it happens.

One cause for it would be that you are on a corporate network, which does antivir analysis and these files trigger a positive.

There is a checksum. Check them.

Should work. Maybe the checksum fails?

Try to install/update them with "rpm" manually. Or create a local directory as repository, tell YaST, and put the files there. -- Cheers / Saludos, Carlos E. R. (from 42.2 x86_64 "Malachite" at Telcontar)

Indeed. There is a Cisco Ironport sniffing everything. I can get the files elsewhere.

Not possible because they require other things be installed. Which is what I am trying to do...

I put the files (obtained outside the corporate network - sneakernet prevailed!) in a local directory, and added that as a repo. Then I 'downloaded' them with zypper -d. After that, the zypper dup completed as the files were now happily present. My 13.1 system is now Tumbleweed. -- Roger Oberholtzer -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

Ironport used to be for email (anti-spam/virus) only, but maybe they've expanded it since Cisco took over. -- Per Jessen, Zürich (0.1°C) http://www.hostsuisse.com/ - dedicated server rental in Switzerland. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

Ah. Ironport. Rings a bell.

Oh, with "rpm" you can always force it.

He. Good :-) Did you compare those rpms with those that you downloaded according to the "rules"? -- Cheers/Saludos Carlos E. R. (testing openSUSE Leap 42.2, at Minas-Anor) -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

I tried wget internally. It also failed. But it left the file for me to play with. They were different. No idea why. -- Roger Oberholtzer -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

Different size, or same size but different content? First case, an antivirus blocked the full file (or timed out). Second case, an antivirus tried to "repair" the virus in the file. Another test you can do is download the file using aria2c and the metalink url. -- Cheers / Saludos, Carlos E. R. (from 42.2 x86_64 "Malachite" at Telcontar)

Slightly smaller. Bigger files get downloaded ok. Odd that it picked on these two so consistently and from different mirrors and by different clients. But all in the company network. On Mon, Jan 9, 2017 at 3:44 PM, Carlos E. R. wrote:

No, not odd at all. Those files trigger a positive in the company antivirus, or trigger "analyze in depth". I mentioned metalinks because it can download chunks from different servers, and compares the checksum to download if it sees an error. This could play havoc with the proxy, and never finish or abort in error. -- Cheers / Saludos, Carlos E. R. (from 42.2 x86_64 "Malachite" at Telcontar)

I have to disable this kind of thing with ZYPP_MULTICURL. Otherwise nothing works. So I think it is getting each file from a single server. On Mon, Jan 9, 2017 at 7:46 PM, Carlos E. R. wrote:

Yes, but my idea is that you run the aria2c command yourself, not zypper, with a metalink url, to find out how it copes in that network of yours. -- Cheers / Saludos, Carlos E. R. (from 42.2 x86_64 "Malachite" at Telcontar)

I could do this. I just need to figure what the command is. I'll report back when I get a chance. Odd that no one else has report a similar problem. I cannot think our company has any special virus detection in place.

Just "aria2c URL". To find out the URL, you go to the download page for the rpm, click on "details", and search for "Metalinks for reliable downloads: ". Pick the ".meta4" one, the first line probably.

The ironclad thing. Ironport, sorry. Not the first time I hear of this problem related to that thing. https://en.wikipedia.org/wiki/IronPort -- Cheers / Saludos, Carlos E. R. (from 42.2 x86_64 "Malachite" at Telcontar)
