As a temporary workaround, you can add to an apt.conf file: Acquire::GzipIndexes "false";
And do a check to ensure no files have GzipIndexes: grep -r GzipIndexes /etc/apt And then delete apt list cache rm -rf /var/lib/apt/lists And then finally update apt-get update -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1876034 Title: apt update crashes with "KeyError: 'suite'" in cnf-update-db if index compression is enabled To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/command-not-found/+bug/1876034/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
