I tried to install a
mutagen package, available according to
$ apt-cache madison mutagen mutagen | 1.40.0-2 | http://deb.debian.org/debian buster/main Sources
apt-get won't deliver:
$ sudo apt-get install mutagen Reading package lists... Done Building dependency tree Reading state information... Done E: Unable to locate package mutagen
$ sudo apt-src install mutagen
The result was catastrophic: it made a grand show, apparently installing the entire python and everything (already present in the system).
So I have to (a) locate the damage and remove it and (b) install mutagen the right way. How am I supposed to go about it?
