Solved! Using apt-get to install libgal have unsolved dependencies, solved them resulted in a system crash. After resolving the boot crash.

Used:

sudo aptitude install libgdal-dev
The following actions will resolve these dependencies: Install the following packages:
1) default-libmysqlclient-dev [1.0.5ubuntu2 (groovy)]
2) libmysqlclient-dev [8.0.21-1 (groovy)]
3) libpq-dev [12.4-1 (groovy)] Downgrade the following packages:
4) libmysqlclient21 [8.0.22-0ubuntu0.20.10.2 (now) -> 8.0.21-1 (groovy)]
5) libpq5 [12.5-0ubuntu0.20.10.1 (now) -> 12.4-1 (groovy)]
6) postgresql-client-12 [12.5-0ubuntu0.20.10.1 (now) -> 12.4-1 (groovy)]

Now I realized that the R updated from 3.6.3 to 4.0.2 automatically. It should not happen I don't know how to stop the automatic updates so I add the repository for bionic-cran35:

´´´´ sudo add-apt-repository 'deb bionic-cran35/' ´´´´

I disable all the downloads from internet (Cannonical, community and property). I'm not supposed to but I don't know how to stop that automatic update for R and giving me troubles again.
