[Bug 1946499] Re: installation of deb-packages with gdebi-gtk shows "dpkg: error: unable to read filedescriptor flags for <package status and progress file descriptor>: Bad file descriptor" in gdebi terminal, package is not installed

The downgrade idea would need to be approved by some leading member of
Ubuntu's desktop team, and since 21.10 is released today, also the SRU
team would need to approve it. (You already know what I think the answer
will be.)

It's correct that I have helped with some routine packaging of VTE a
couple of times, but that does not make me "familiar with VTE codebase".
I'm not. Packaging and tweaking upstream code are different things.

So it boils down to neither you nor me has the sufficient skill to dig
into the code, and that somebody who has needs to give it priority.
Maybe Martin W., maybe somebody in Ubuntu's desktop team.
