Re: [bitfolk] Problems upgrading to Ubuntu Xenial Xerus (16.04)

This appears to only occur for the file that is downloaded during do-release-upgrade that comes from a URL like: /ubuntu-uk/dists/xenial-updates/main/dist-upgrader-all/current/xenial.tar.gz Deleting the file from the apt-cache will cause a new copy to be fetched from the Ubuntu mirror and then things work, so it seems like apt-cacher-ng is not able to tell when those files have been updated. I'm not sure if that is a bug in apt-cacher-ng or a bug in Ubuntu's mirror setup. Probably acng since otherwise I suppose there'd be huge problems with more normal HTTP proxies like squid. Anyway, I have now reconfigured BitFolk's apt-cacher-ng instances to not cache any URI like: /dist-upgrader-all/.*\.tar.\gz$ so now none of these files will be found in cache; they will always be downloaded from the real mirror each time. (There are tons of other tar.gz files in the cache and they all work fine, otherwise we'd see hash mismatches there too.) Cheers, Andy -- https://bitfolk.com/ -- No-nonsense VPS hosting
