@chaonatic Manually edit /opt/fog/.fogproject and change the line starting with packages=.... Make the parts with “mariadb…” to read like this: MariaDB-client MariaDB-server (yeah, upper case M …)
If that doesn’t work we need the installer log that you find in the same directory where you run the installer - e.g. fogproject/bin/error_logs/...!
@Sebastian-Roth As far as I understand, any tool that uses BLKRRPART could be prevented access because of udev event handling.
It’s usually very fast and therefore unlikely to cause issues, but since it is executed parallel to everything else it can potentially get in the way from time to time.
As far as I know, other programs that interact with the storage device act in the same way and also use BLKRRPART (such as fdisk and hdparm)
For now, I’d say, leave it as is and monitor for reported problems. This problem is rare enough on its own already (personally haven’t come across it at all) that it doesn’t really warrant changing everything with the possibility of the affecting something else. (doesn’t look like it should, but never know)
edit: Important to note that Kernel version could affect how BLKRRPART functions and what not plus the udev events would be handled by the kernel as well afaik, so perhaps it’s as simple as the kernel versions?
