This very much looks like a bug int Aptdaemon's PK compatibility layer to me. At this point, it likely makes no sense to fix this issue, since that code has been dropped after the Xenial release.
@tlc: This will likely be a won't fix bug, please upgrade to Bionic if you can. If you can't upgrade, you can try to switch from the compat layer to the real PK daemon, if the system allows you to do that: sudo apt purge python3-aptdaemon.pkcompat ; sudo apt install packagekit ** Package changed: packagekit (Ubuntu) => aptdaemon (Ubuntu) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1774491 Title: pkcon install fails -- proxy?
