Using 20.04 current build still see: $ python
Command 'python' not found, but can be installed with: If I run sudo apt install python Package python is not available, but is referred to by another package. This may mean that the package is missing, has been obsoleted, or is only available from another source However the following packages replace it: python2-minimal:i386 python2:i386 python2-minimal python2 2to3 E: Package 'python' has no installation candidate This has an effect on an upgrade to 20.04 of uninstalling any package that depends on "python" for example slack-desktop. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to python3-defaults in Ubuntu. https://bugs.launchpad.net/bugs/1863532 Title: Invoking "python" brings inappropriate response from command-not-found when python3 installed Status in command-not-found package in Ubuntu: Triaged Status in python3-defaults package in Ubuntu: Triaged Status in command-not-found source package in Focal: Triaged Status in python3-defaults source package in Focal: Triaged Bug description: 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.
