Removed python3 hoping to reinstall it, but cannot do it

Solution 1:

You could try aptitude.

Install aptitude like this:

sudo apt install aptitude

Or if that didn't work, download the aptitude .deb package from here for 64 bit and install it like this:

sudo dpkg -i aptitude_0.8.10-6ubuntu1_amd64.deb

Or install the downloaded package by double clicking it so it opens in the GUI package manager (ubuntu-software) and install it from there.

After that, nstall python3 like this:

sudo aptitude install python3

Aptitude is good at resolving dependencies and will most likely succeed in your case.
