Recently upgraded to Fedora 43. The upgrade went fine (i think). But immediately I noticed the error message.

youknowwho@fedora \~> dnf
dnf: /usr/local/lib/libpcre2-8.so.0: no version information available (required 
by /lib64/libglib-2.0.so.0)

I have been searching on this and most answers say that this is just a benign warning and it does not affect anything. I just don’t want to see the warning every time I enter a command. Is there any way I can fix it? Thanks in advance.

You should have a file named /usr/lib64/libpcre2-8.so.0 and the file /usr/local/lib/libpcre2-8.so.0 is usually not supposed to be found on your system.

I do. I tried (re)installing the package with dnf and pcre2 libs files are there:

youknowwho@fedora ~> ls /usr/lib64 | grep pcre2
libpcre2-16.so
libpcre2-16.so.0
libpcre2-16.so.0.15.0
libpcre2-32.so
libpcre2-32.so.0
libpcre2-32.so.0.15.0
libpcre2-8.so
libpcre2-8.so.0
libpcre2-8.so.0.15.0
libpcre2-posix.so
libpcre2-posix.so.3
libpcre2-posix.so.3.0.7

Try this workaround:

sudo sed -i -e 's/^/#/' /etc/ld.so.conf.d/local.conf
sudo ldconfig
unset LD_LIBRARY_PATH

It solved the problem. Not sure why it occurred after upgrading to 43. but thank you very much.
