How do you reinstall Ubuntu after deleting python3.6? [duplicate]
Solution 1:
Changing or deleting the standard python version of Ubuntu is a unrecoverable error.
You need to reinstall.
Boot from a live DVD or USB and reinstall.
If your live DVD/USB is the same version as the installed Ubuntu version, you will see a "Reinstall" option.
This will reinstall the system in the same setup as the existing installation, without formatting the partitions. That way, your user data and user configuration will be preserved
