A package which isn't even installed can not be the cause of a problem… and you are not using a "tor+" source (which is enabled by that package).
Looks for me like you would need to "apt update" as the data you have locally on your system is too old and references no longer existing files … a few years ago. Probably not that helpful now years later, but so is keeping this unactionable bugreport open. ** Changed in: apt-transport-tor (Ubuntu) Status: Confirmed => Invalid -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1682320 Title: apt-transport-tor causes errors saying "Failed to download repository information" To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/apt-transport-tor/+bug/1682320/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
