but I delete it because it won't lunch.
I re install it and try some twicks from the community, but still don't work. Then this morning, I try to install some utility from terminal and it replaying me this problem.
What happened there that sent everything into a tizzy...:
The initial installation was done without the Gambas repository. For some reason (that I do not fully understand) the Ubuntu Universe contains an incomplete copy.
When that was installed, it was partially installed... So did not work.
When you removed it, it partially removed, leaving behind packages (This is a good reason to always remove packages with the --purge parameter).
With APT still holding the original Ubuntu version in the cache, when you tried to install or remove it completely, dpkg was put in a position to recognize BOTH and it cannot do both.
So, you needed to add the repository, then force the overwrite, then clean the apt cache, then force the install.
Once done, you should be able to remove it (If you still want to) with
sudo apt remove --purge gambas3 gambas3-dev-tools
If so, you may also want to remove the repository for it, as well.
