Hi Robert, you are welcome.
It seems that you own (rgampe.rgampe) the directory /software/ccp4-8.0 . You should revert the ownerships in /software/ccp4-8.0 from root.root with sudo chown -R rgampe.rgampe /software/ccp4-8.0 so that in the future you don't need sudo for updates. Your real problem seems to be the Qt installation; I think that the error message qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" even though it was found. This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem. prevents the graphics of the CCP4 programs from working properly. I have no idea, though, if your Qt is too new or too old or somehow corrupted. I've never heard of POP_OS or the like so maybe it's just not compatible with CCP4.
