Comment 4 for bug 1898729

Ok. If this was initially installed using a currently-supported release, it might be good to look back at the logs and at the code in that version of the installer, to see if there's something we should fix wrt the shim-signed package being marked as auto-installed instead of manual.

(But a system installed here using 19.10 doesn't have shim-signed marked as auto-installed, so I guess any bug in that regard may be rather old.)
