Problem with Ubuntu 22.04 NGSolve instalation

I am trying to install ngsolve in Ubuntu, as previously tried on windows and did not work. I am following the installation guide provided on the webpage obtaining E: Couldn’t locate ngsolve package

This happens after executing the sudo apt-get install ngsolve command, and having previously added the ppa repository and all.

I don’t know why this is happening, but I would appreciate a solution!
Thanks in advance!!

the recommended way to install is via pip, on all platforms.
Did you try that ?
