Public bug reported: Ubuntu Mate 20.04 development release, upgraded from 19.10. I don't have python 2.7 installed, but have python 3 installed as per default.
Please see ascii-cast at https://asciinema.org/a/SZR20NHz2FN6N6O1hj2Mqmnv8 . Running `python` brings up text from command-not-found which suggests installing `python3` as a solution to the missing command. `python3` is already installed, is a later version than the one indicated by command- not-found and does not supply a binary or symlink named `python`. $ apt policy python python: Installed: (none) Candidate: (none) Version table: 2.7.17-1 -1 100 /var/lib/dpkg/status $ apt policy python3 python3: Installed: 3.8.0-3 Candidate: 3.8.0-3 Version table: *** 3.8.0-3 500 500 http://gb.archive.ubuntu.com/ubuntu focal/main amd64 Packages 100 /var/lib/dpkg/status $ apt policy command-not-found command-not-found: Installed: 19.10.0 Candidate: 19.10.0 Version table: *** 19.10.0 500 500 http://gb.archive.ubuntu.com/ubuntu focal/main amd64 Packages 500 http://gb.archive.ubuntu.com/ubuntu focal/main i386 Packages 100 /var/lib/dpkg/status I don't know whether this is a bug in python3 or command-not-found (the latter of which doesn't seem to have been updated for 20.04 yet). i don't know if it is intentional that `python3` will not provide a binary or symlink named `python`. if that is the case, the output of `command- not-found` should be updated to reflect that.
