Something is not well in Ubuntu land. This morning, when upgrading my media PC, "apt" kept segfaulting. After manually downloading and upgrading apt and libapt, I fixed that. I then did apt update followed by apt upgrade -y. This is the result:

I deleted the offending .deb file and did apt --fix-broken install but I just keep getting the same result.
I manually downloaded, and tried to install, libgl1-amber-dri and it tells me that it depends on "libglapi-mesa (>= 23.0.4)". I tried to manually download that, and after initially getting a broken link message, I succeeded.
The apt --fix-broken install then worked.
I would try to submit a bug report, but don't know how or where.
Why is this broken? How did the apt system manage to download what looks like a partial file for that .deb file?
