Manually refreshing the apt-cacher-ng cache did not solve the issue. The package list file at:
http://archive.ubuntu.com/ubuntu/dists/xenial-updates/main/binary- amd64/Packages.gz does not have cups-daemon in it. It seems it has not been updated with the new dependency on the package servers. The package list at: http://archive.ubuntu.com/ubuntu/dists/xenial/main/binary- amd64/Packages.gz contains cups-daemon but with the outdated dependency. I checked these files by manually pulling them via web browser. There is no cache or proxy involved on my end. Here's a couple of hacky oneliners to test with. Check dists/xenial: # wget -qO - http://archive.ubuntu.com/ubuntu/dists/xenial/main/binary-amd64/Packages.gz | zcat -c | grep -A 20 'Package: cups-daemon' | grep '^Package\|^Depends' | grep --color -E 'libcups2|$' Check dists/xenial-updates: # wget -qO - http://archive.ubuntu.com/ubuntu/dists/xenial-updates/main/binary-amd64/Packages.gz | zcat -c | grep -A 20 'Package: cups-daemon' | grep '^Package\|^Depends' | grep --color -E 'libcups2|$' The second test returns nothing, since cups-daemon isn't in the package list yet. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1676376 Title: package cups-daemon 2.1.3-4 failed to install/upgrade: subprocess new pre-removal script returned error exit status 1 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/cups/+bug/1676376/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
