snap looks for its own copies of system files within the file tree for each snap. I suggest sudo apt install mlocate sudo apt update sudo locate ibQt5Core.so and see what you see. I don't have the OpenSCAD snap, but gravit designer is similar This is how it looks on disk /snap/gravit-designer/29/usr/lib/x86_64-linux-gnu/libQt5Core.so.5 /snap/gravit-designer/29/usr/lib/x86_64-linux-gnu/libQt5Core.so.5.5 /snap/gravit-designer/29/usr/lib/x86_64-linux-gnu/libQt5Core.so.5.5.1 And this is the links -rw-r--r-- 1 root root 5052920 May 13  2017 libQt5Core.so.5.5.1 lrwxrwxrwx 1 root root       19 May 13  2017 libQt5DBus.so.5 -> libQt5DBus.so.5.5.1 lrwxrwxrwx 1 root root       19 May 13  2017 libQt5DBus.so.5.5 -> libQt5DBus.so.5.5.1 If say the links from libQt5DBus.so.5 to the actual file is missing you would get your error On 11/5/21 10:30 am, Ron Wheeler via Discuss wrote: > _______________________________________________ > OpenSCAD mailing list > To unsubscribe send an email to discuss-leave@lists.openscad.org -- Jeremy

oops, I cut and pasted the wrong section of the listing.
