[Bug 2052328] Re: openssh-client encounters MAC algo issue with EL8

[Marc Deslauriers]

The Oracle Linux I'm running is the v8 developer preview, as that is the
only freely downloadable version.

I couldn't reproduce the issue with openssh-server-8.0p1-17.el8.x86_64.

Since I can't get newer packages from Oracle with this version, I
installed openssh, openssh-askpass, openssh-client and openssh-server
8.0p1-19.el8_9.2 from RockyLinux into the Oracle install, and I still
can't reproduce the issue.

Could someone perhaps email me the 4 Oracle binary rpms for the packages
listed above so I can try them?

Title:
  openssh-client encounters MAC algo issue with EL8

Status in openssh package in Ubuntu:
  New

Bug description:
  Ubuntu 22.04 system connecting to an Oracle Linux v8 host.  The
  following error occurs regardless of the the MACs specified (or not)
  in sshd_config:

  Corrupted MAC on input.
  ssh_dispatch_run_fatal: Connection to XX.XX.XX.XX port 22: message authentication code incorrect

  Presumably, this may happen on any RHEL v8 variant. Note that
  connecting to Enterprise Linux v7 work as well as other Ubuntu hosts.
  Downgrading to previous version of openssh-client fixes issue.

  apt install openssh-client=1:8.9p1-3
