What's the default Python version in Ubuntu 22.04?

Question

I am trying to upgrade from 20.04 to 22.04

During update, I get an error

Your python3 install is corrupted. Please fix the ’/usr/bin/python3’ symlink.

I know changing the symlink to the correct version should help. But I cannot Find info as to which version of Python does Ubuntu 22.04 ship with.

If anyone can tell that will be great .

readlink -f /usr/bin/python3 /usr/bin/python3.10 python3.10 is default. — nobody, Commented Jan 20, 2023 at 12:35
My current version on 20.4 is Python 3.10.9, but upgrade is not going forward. What is the minor number that showing on your side ? — frewper, Commented Jan 20, 2023 at 12:47
Does sudo update-alternatives --config python3 help? Or did you manually change the link before? — Bodo, Commented Jan 20, 2023 at 13:36
Never, ever change the Ubuntu-provided version of Python. That causes big problems, as you have discovered to your sorrow. Use virtual environments for other releases of Python. Or use six-month releases of Ubuntu (instead of LTS) to get newer software. You must uninstall those non-Ubuntu Python 3.10 packages and restore your older version of Python for the release-upgrade to work. Or backup your data and fresh-install 22.04...or 22.10. — user535733, Commented Jan 20, 2023 at 14:38

https://packages.ubuntu.com will readily provide current package version information for all supported releases of Ubuntu.

For example, here's a search of that website for the python3 package in jammy (22.04):

Does it mean I need to downgrade from 3.10.9 to 3.10.4 ?

No, it means the final result will be 3.10.4. You must downgrade to a lower version (3.10.3 or lower) AND disable all non-Ubuntu sources so apt will properly upgrade you to the correct version from the correct source.
