I'm not aware of any performance issues in those parts of apt, and spent a considerable time optimizing it. You probably want to strace or gdb apt when it's hanging and figure out where the issue is, because there's nothing that can be done here by anyone else so far. ** Changed in: apt (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to apt in Ubuntu. https://bugs.launchpad.net/bugs/1875190 Title: Apt update takes around a full minute to read state information when I run it for the first time since boot even though there are no updates available.
