man pages broken after dist-upgrade

After a recent dist-upgrade, I have broken man pages. Symptoms are that man <any command here> refuses to load anything and shows a blank console, except for the line in the upper left:

Manual page man(1) line ?/? (END) (press h for help or q to quit)

After quitting, I get the following error line:

man: command exited with status 4: /usr/lib/man-db/zsoelim | /usr/lib/man-db/manconv -f UTF-8:ISO-8859-1 -t UTF-8//IGNORE | preconv -e UTF-8 | tbl | nroff -mandoc -rLL=195n -rLT=195n -Tutf8

This isn't helpful for me. I tried sudo mandb and sudo mandb -c with no success.

Solution 1:

The following commands worked for me:

apt install apparmor-utils
aa-disable /usr/bin/man
