keybase fails to upgrade via apt

[RileyStarlight]

The package remains as partially installed, and keybase services are restarted with each apt run.

dpkg: error processing keybase package (--configure): subprocess installed keybase package post-installation script returned error exit code 1.

However, the application seems to update and launches correctly. The /keybase mount folder becomes corrupted?

$ ls -alh / | grep keybase
ls: can't access 'keybase': The other end of the connection is not connected
d?????????   ? ?           ?              ?            ? keybase

Keybase version: 5.9.0-20220120174718+95a3939b3a OS: Linux Mint 19.3

Had the same issue. Used fusermount -u /keybase to unmount the fuse "device". Killed keybase and then ran apt autoremove just to test it out. apt came back with the following:

I can't find anything using dpkg or apt that would indicate why keybase is treated as relevant in invocation of apt. The package is seen as installed and not broken.

The app works fine, tough. I'm running Ubuntu 20.04.3 fully updated. What can I do to add more info?
