I have recently upgraded from ModemManager 1.16 to 1.18 via apt on Ubuntu Jammy, which turned out to be a huge mistake, as the new version introduces many bugs. I have now tried to remove version and reinstall version 1.16, but it seems like it is no longer available, only versions 1.12 and 1.18 are available.
I have found the following launchpad archive, but it seems to only support Imprish while I am on Jammy.
How can I downgrade back to my desired version?
