Hi all. If when opening the editor on the new LTS 22.04 you get the error 'No useable version of libssl' it's due to a change in the libssl version. The fix that worked for me was manually downloading the 'libssl1.0.0_1.0.2n-1ubuntu5.8_amd64.deb' package from http://security.ubuntu.com/ubuntu/pool/main/o/openssl1.0/
NOTE: download the right version for your architecture
then, in the download location: sudo dpkg -i libssl1.0.0_1.0.2n-1ubuntu5.8_amd64.deb
restart the unity editor and hopefully you're back in the game.
