Support Ubuntu 22.04

[javierm]

Ubuntu 22.04 was released a few months ago. Currently, we only support Ubuntu 18.04 and Ubuntu 20.04.

I investigated this issue and tried running the installer against a 22.04 virtual machine. Here are the issues I found:

• Nodejs 10 is not available for Ubuntu 22.04. I finally used Nodejs 12 instead.
• Ubuntu ships openssl3 while RVM needs the openssl1 development libraries to compile the ruby version. At the time of writing, there is an open issue in the RVM repository regarding this issue, and it seems it is not yet clear how is gonna be solved.
• I had to remove the host entry from the database.yml to avoid a Segmentation fault error with the pg gem. Adding gssencmode to the database.yml did not work for me.
• As MongoDB still uses openssl1 instead of openssl3 the MongoDB packages cannot be installed in Ubuntu 22.04.

Since rvm/rvm PR5308 was merged, the OpenSSL dependency is no longer a problem as now RVM provides a downloadable binary for Ruby 2.7.6 and newer versions on x86/64 and aarch64 architectures.

Here is the binary for x86_64 for the 2.7.7 version (current ruby version):

Here is a link to the build that makes me realize about the MongoDB issue.

Even with the precompiled version, we still need the openssl1package.

For the current CONSUL Ruby version (2.7.7) we must install the missing openssl1 libraries manually. Another option is to upgrade CONSUL to Ruby 3 and hopefully forget about this 🤞🏼 .

The RVM issue mentioned the same problem with Ruby 3.0 🤔, so I guess we'd have to upgrade to Ruby 3.1, which unfortunately will take some time 😅.

After the changes in pull request #221, the current status is that the installer fails on Ubuntu 22.04 in the "specs" step; testing a URL results in a 502 error.

Debugging shows Puma is running and its socket has 777 permissions. However, in the nginx logs, we get:
