Install OpenSSH 8.3 on AlmaLinux 8

Hi, I am using AlmaLinux 8.  The version of SSH that ships with this OS is 8.0.  I would like to be able to use FIDO2/YubiKey with the SSH login, however that functionality was added in either SSH 8.2 or 8.3.

Is there a way that I can install SSH 8.3 without breaking other things?

  Hey there!  Usually, the short answer is "no" - when you start messing with openssh or openssl, it touches many things on the server.  Try running this command to get a list of dependencies for openssh

  yum deplist openssh

  and you'll see some other heavy hitters in there, like glibc.

  I personally can't recommend it - AlmaLinux 9 has 8.7:

  [root@a9---plain ~]# rpm -qa | grep -i openssh
  openssh-8.7p1-38.el9_4.4.x86_64

  Would that get you what you need?

  Thank you.  That's what I was concerned about.

  Yes, the ssh version included with Alma9 would be fine.  However, I don't think there is currently a way to upgrade cPanel from Alma8 to Alma9 (without doing a new install and backup/restore).  Is that correct?  I used Elevate to go from Centos 7 to Alma 8.  But as far as I know, that is as far as we can go.

  That is still correct - we have it on the "future" section of the roadmap here:

  https://features.cpanel.net/c/89-elevate-alma-8-to-alma-9

  but there isn't any type of timeline for when that tool will be released.  So at least at this point, you'd have to do a full migration.
