Hello dbannon.
I was able to solve following some of its guidelines, I did the following:
- I uninstalled all versions and dependencies of the lazarus and cleaned the previous installation folders.
- I downloaded all the dependencies of the site
https://sourceforge.net/projects/lazarus/files/Lazarus%20Linux%20amd64%20DEB/Lazarus%202.0.0 and installed the packages in the following order:
1. fpc-laz_3.0.4-1_amd64.deb
2. fpc-src_3.0.4-2_amd64.deb
3. lazarus-project_2.0.0-0_amd64.deb
After these procedures the Lazarus 2.0 IDE opened normally.
I hope this tip also works for the other forum members if this happens.
Thanks for the help dbannon.
