Was just doing a (very) belated update on a 7.5 system and ran into this set of errors:

I then browsed to the mirror shown above and downloaded the files with no trouble. I then did “yum localupdate” for the three downloaded files and they installed just fine.

so, anybody know why we’re getting the 416 error from yum but not from firefox?

a little searching for that error indicates it is some kind of problem on the web host, I think. but it’s weird.

I don’t need help, I’m good, but perhaps someone needs to look at whatever mis-configuration on the host(s) causes that.

I originally left the repo file alone so it attempted to use the repolist but every repo failed. I then changed it to use the baseurl but it didn’t help. So whatever the problem is, it isn’t with just a single host.

  • Hi Fred,

    Ran into this yesterday. It seems to be a delta rpm problem. Firefox is working because it’s downloading the whole rpm, avoiding the issue.

    setting deltarpm=0
    in /etc/yum.conf is an equivalent workaround, and fixed the issue for me.

    I’d appreciate someone who knows more about how delta rpms work weighing in on what the actual issue is.

  • Not sure what happened with the drpms, but I will regenerate all the polkit drpms with the upcoming ghostscript release later this morning.

    I added drpm tests to our pre-release CI tests as well.

  • This is not the first time we have had issues with drpms in the update tree.

    Would anyone be opposed to taking away deltarpms from the repositories?

    They take up lots of space and they have cause multiple issues in the past.

    Thoughts?

  • Johnny, thanks for looking into this.

    I, for one, have no issue with there being no drpms. their purpose was, as I recall, to save bandwidth. this may still help for busy mirrors, but for most of us bandwidth is no problem. Someone on dialup may disagree, but how many of those are there these days?

  • Due to the disk churn deltarpms need and our own internal mirroring of CentOS packages, one of the first things I do post-install is disable deltarpms.

    However, I’m sure there are users on limited connections (either monthly cap or slow) who appreciate the deltarpms who are not on this list to cast their vote.

    I suppose the only way to find out is to take them away and if there is outcry, put them back.
