CentOS

There is no copy of -56 available for CentOS 8 anyway. It died in 2021 and there have been no fixes produced for it since then.

Unfortunately Red Hat discontinued CentOS 8 at the end of 2021and the current version of RHEL 8 is now 8.9. Since new point releases come out every 6 months your system is now at least 4 whole years out of date. You need to change distributions to get to 8.9. I would recommend switching to one of Ro...

There are no known problems with the CentOS 7 repos or mirrors. I suspect the problem is your end and that you are behind some form of caching web proxy that has helpfully saved a broken copy and is serving it to you instead of the real thing. There is an http_cahcing= parameter you can add to yum.c...

Hmm, actually you may not need to do that at all. The vgdisplay output you posted says Alloc PE / Size 102142 / 398.99 GiB Free PE / Size 76801 / 300.00 GiB So the current volume group has 300GB free in it already that you can use to add to the centos-root LV. You would need to run something like lv...

Start by running df -hT /home and if it says it is xfs (the default) tehn know that the only way to shrink that is to backup its contents, blow away the filesystem, resize the device smaller, make a new filesystem on it, and then restore the data.

Check your user's /home/$user/.ssh/config file for directives like "Host localhost\nport 55555". Also check /etc/ssh/ssh_config on the client side as jlehtone suggests. That is the systemwide version of .ssh/config. Also, something does not add up., You show that .etc.redhat-release says CentOS 7 bu...

I admit those last three entries prefixed with “10000:” are a bit odd, but that’s how the machine reports them The whole lot are odd. I've not got a physical machine in about 40 or 50 of them that has that extra field at the front of the PCI id. All mine are of the format 07:00.0 SATA controller [0...

I just booted my Dell XPS 13 Plus 9320 - 12th gen i5-1240P (4 and 8 cores) and my lspci there is not showing those strange entries, just the normal ones of the format 01:00.0 or 00:1f.5. I have never seen PCI entries like yours before - they appear to have an extra 5 digit number prefixed at the sta...

You should report this on issues.redhat.com under RHEL then I think there is a version number "Stream 9" or something like that. No-one from RH reads this forum so no-one who either cares or can fix it will ever see these posts. There is only one driver for all SATA chipsets and that is the ahci mod...

Edit the kernel comand line at the grub menu and remove 'rhgb' and 'quiet' and then continue with the boot. It will not change the outcome but you should now be able to see any error messages issued that were previously invisible.
