"reporting bugs to the effect that a no-change update should finish instantly."
By definition, if the on-disk copy is corrupt, there is an change-update available. The algorithm for update should look like this: - does the local copy exist? No -> update available - is the local copy valid (checksums match)? No -> update available - does the remote repo report a change? Yes -> update available "That said, files of size 0 could be made always invalid" My case happened to be corruption of the form of an empty file. Checking the checksum will detect all forms of corruption. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1809174 Title: apt doesn't detect file corruption in /var/lib/apt/lists To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/apt/+bug/1809174/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
