Cannot load module /usr/lib/x86_64-linux-gnu/gtk-3.0/3.0.0/immodules/im-ibus.so

Hello,
I’m building snap with desktop launcher on ubuntu 18.
It’s systray application and I always get this error message when I launch snap.
Do you have any clue for this issue?

The same issue in Simple-scan not working
Thank you.

This is a classic confinement issue. Your application is trying to load libraries from the wrong location, which is causing the warning you described in your post. To fix you need to remove or override the parts of LD_LIBRARY_PATH that point to /usr/lib because libraries found there are almost certain to cause issues with your app. Snapcraft should be setting the ELF headers’ RPATH feature but this might be being set to an incorrect value.

Hello,

Thanks for your reply.
I tried to print out the value of LD_LIBRARY_PATH and it actually does not content /usr/lib

For example:

LD_LIBRARY_PATH=/snap/cells-sync/x1/lib/x86_64-linux-gnu:/snap/cells-sync/x1/usr/lib:/snap/cells-sync/x1/usr/lib/x86_64-linux-gnu:/snap/cells-sync/x1/lib:/snap/cells-sync/x1/usr/lib/x86_64-linux-gnu/libunity
