All of my Linux machines, servers and laptop/workstations, were running Enterprise Linux under the Scientific Linux distro from Fermilab/Cern.
With the demise of that distro (no SL8), we weighed our alternatives and have elected Ubuntu LTS. The machine from which I am posting this is a mobile workstation ("professional" laptop -- HP Zbook) now running Ubuntu 20.04.1 LTS.
With Red Hat, as with SuSE, the only lists available to those who do not license the product (technically, the installable "supported" port/distro) is not the same as the SL Users list that regularly have other experienced professionals posting and responding.
When it became apparent that some of the current non-beta production releases of applications we needed were no longer compatible with SL 7, but needed EL 8, the switch to Ubuntu LTS was undertaken. Is there any list other than this website that is the equivalent of the SL Users list that had answers from the professional paid maintainers of SL (at Fermilab) and from those who maintained EL repositories (e.g., ELrepo)?
Thank you any information. I am not allowed to post this to META where I suspect the question belongs because I do not have a 5 or higher. Take care. Stay safe.
