After installing obs-ndi, apt upgrade returns the following error message.
/sbin/ldconfig.real: /usr/lib/libndi.so.4 is not a symbolic link
The following command proves that the file is not a symbolic link.
% cd /usr/lib % ls -l | grep libndi -rwxr-xr-x 1 root root 4663328 May 14 19:35 libndi.so -rwxr-xr-x 1 root root 4663328 May 14 19:35 libndi.so.4 -rwxr-xr-x 1 root root 4663328 May 14 19:35 libndi.so.4.5.1
A simple solution is as follows:
sudo mv /usr/lib/libndi.so.4 /usr/lib/libndi.so.4.back sudo ln -s /usr/lib/libndi.so.4.5.1 /usr/lib/libndi.so.4
