Public bug reported: This is on the forums here (http://www.ubuntuforums.org/showthread.php?t=245059&highlight=gzip)
It is random and it looks like something (possibly a time out) corrupts the file so that updating always fails. Other repositories will work fine, even those which are also archive.ubuntu or security.ubuntu. When running update-manager an affected repository will fail with: http://security.ubuntu.com/ubuntu/dists/dapper- security/main/binary-i386/Packages.gz: Sub-process gzip returned an error code (1) I can't be much more precise as to the trigger but the solution posted in the forums (using a blank sources.list, running sudo apt-get update, reinstating sources.list and running sudo apt-get update again) clears up the problem. ** Affects: apt (Ubuntu) Importance: Untriaged Status: Unconfirmed -- gzip error when updating packages https://launchpad.net/bugs/59353 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
