unable to run pip

[snippsat]

I don't why this still is problem,maybe Gribouillis advice is the easiest one.
Gave some advice in post #12

i would be tempted to manually wipe out all python stuff and start over, but ubuntu now depends on python, making that difficult to do.

You never wipe out the default Python install,just install a new version using eg Install Python 3.10 or pyenv Simple Python Version Management.
Quick demo using pyenv to install Python 3.101.5 on Mint 19.

tom@tom:~$ pyenv install 3.10.5

WARNING: The Python lzma extension was not compiled. Missing the lzma lib?
Installed Python-3.10.5 to /home/tom/.pyenv/versions/3.10.5

tom@tom:~$ pyenv global 3.10.5
tom@tom:~$ python -V
Python 3.10.5
# Test pip is build with this Python version,no need to go a repository to get it
tom@tom:~$ pip -V
pip 22.0.4 from /home/tom/.pyenv/versions/3.10.5/lib/python3.10/site-packages/pip (python 3.10) 

Same with the link if build from source(recommended way).

By default, PIP3.10 should be installed, which is the most used package manager for Python
