I just installed Unreal Engine 5.0.3
in Ubuntu 22.04
and had the error
No usable version of libssl was found
when trying to run the template with C++
I could solve the issue by running sudo apt install libssl-dev
or
$ wget http://archive.ubuntu.com/ubuntu/pool/main/o/openssl1.0/libssl1.0.0_1.0.2n-1ubuntu5_amd64.deb
$ sudo dpkg -i libssl1.0.0_1.0.2n-1ubuntu5_amd64.deb
