Hi there! Thank you for worry about it!
First of all I tried the option of install both, astah-pro and community, by the apt repos firstly. In this case I receive an error related to the gpg key, the repos was "no signed".
Then I tried the .deb package installation option. Here I tried both astah (pro and community), I downloaded all the versions of both to make sure that it wasn't an error of a single version, then when I tried to do the tipical install of a .deb, which is by "dpkg -i package.deb" it throw an error in the compression of the file I think. And that's all I remember.
I hope to be helpful to someone else.
