I can confirm that acng running the version in jammy triggers the problem with PPA in the clients it serves (which may or may not be running jammy). Going by the fact that the version from impish when installed on jammy does not have this problem and runs fine otherwise, it looks like a regression.
Maybe it's best to downgrade the version in jammy back to the one from impish until a solution can be found. I'd to see an LTS see the light of day with this regression. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1960264 Title: 503 errors for Jammy PPAs To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/apt-cacher-ng/+bug/1960264/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
