_ped.IOException: Partition(s) 2, 3 on /dev/sda have been written, but we have been unable to inform the kernel of the change, probably because it/they are in use.  As a result, the old partition(s) will remain in use.  You should reboot now before making further changes.

Bit confused. You ran the ISO installer on top of the Alma setup? The ISO installer should be blowing away anything already on the disk. Not retaining any existing partitions. Or is this from you running the web installer on an existing system?

I run installer from USB. It should wipe the partitions and I think it did but then crashes. I restarted and run installer once again (now as I'm assuming on wiped disk) and run perfectly fine. Omarchy is installed.

I wrote about AlmaLinux to indicate that I got the default partitions and file system from the Alma installation on the sda.

p.s. I edited a little bit my initial message to make it more clear.

Ah, sorry, I misunderstood. Think we're going to nee @Torxed to chime in on this error from archinstall. Thanks for testing!
