[lug] A head scratcher for your weekend

[Louis Krupp]

Zan mentioned ldconfig. Have you run ldconfig -p?

Also, you showed this:

# ls -alh /usr/lib/x86_64-linux-gnu/libQt5Core.so.5*
lrwxrwxrwx 1 root root   20 May 12 07:03
/usr/lib/x86_64-linux-gnu/libQt5Core.so.5
-> libQt5Core.so.5.10.1
lrwxrwxrwx 1 root root   20 May 12 07:03
/usr/lib/x86_64-linux-gnu/libQt5Core.so.5.10
-> libQt5Core.so.5.10.1
-rw-r--r-- 1 root root 5.0M May 12 07:03 /usr/lib/x86_64-linux-gnu/libQ
t5Core.so.5.10.1

The last file doesn't have execute permission. Could that be part of the
problem? Reinstalling whatever package the library came from might be worth
trying.
