I'm trying to change temporarily to a specific Ruby version 2.7.6.

But encountered the following error.

Ubuntu 22.04 comes with OpenSSL 3.0.2, but Ruby versions older than I think 3.0.4 still need the old OpenSSL 1.1.1x. The build process is looking for the header files of OpenSSL 1.1.1x, doesn't find them and tells you that: cannot load such file -- openssl.

The current version of the rbenv plugin ruby-build should take this situation into account and download the fitting version of OpenSSL, in addition to the Ruby sources:

Installed openssl-1.1.1q to /home/henning/.rbenv/versions/2.7.6

You probably need to update your installation of ruby-build (and rbenv in general) to the most current version.
