I tried to rim robo3t-1.1.1-linux-x86_64 downloaded from https://robomongo.org/ and got the following error when trying to run it:
This application failed to start because it could not find or load the Qt platform plugin "xcb" in "". Available platform plugins are: xcb. Reinstalling the application may fix this problem. Aborted
Trying to install xcb via apt install xcb doesn’t change the behavior. Then I found a solution by removing all libstdc++* files from the lib directory in the extracted directory:
rm lib/libstdc++*
