[Bug 2008151] Re: package base-files 12ubuntu4.2 failed to install/upgrade: subprocess new pre-removal script returned error exit status 1

[Seth Arnold]

Your logs suggest that your /usr/bin/dpkg has been corrupted. There is
no easy way to recover from this situation.

If you have another computer of the same architecture and running the
same release, you can copy the /usr/bin/dpkg file from one computer to
the other. If you don't have this, you can use apt download dpkg to
download the dpkg package, use ar x to unpack the dpkg package, and then
tar xf the data.tar.* file that was created. Then you can copy the
usr/bin/dpkg  from that over your /usr/bin/dpkg.

Good luck.
