On a friend's machine, Ubuntu had somehow managed to install both the APT docker and the Snap docker. This caused the entire disk to fill with log messages from the snap docker trying and failing to start, since another docker was already running. Removing snapd is the first thing I do on any Ubuntu machine now, whether mine or my friends'. This now requires adding a PPA for Firefox since 22.04 but otherwise I have never had to deal with snap again.
