The GiD InstallJammer installer (e.g GiD 14.0.1 y 14.1.1d) has problems with the ‘Ubuntu 18 Gnome desktop environment’, and become locked asking the install language window.

Note: once locked is possible to find the id of the locked process with something like

ps -auxw | grep gid14

and then can kill the process with

kill <pid>

To avoid GUI installer problems it is possible to run it without GUI with the flag --mode console

e.g.

./gid14.1.0d-linux-x64-Install --mode console
