Where can I find /lib/ld-lsb.so.3 for Ubuntu 21.04?
The answer was that ld-linux.so.2 is identical to ld-lsb.so.3. A symbolic link solved my problem.
sudo ln -s /lib/ld-linux.so.2 /lib/ld-lsb.so.3
I now have a large supply of salty comments about Linux binary support and people who believe renaming libraries is a good idea.
