My Ubuntu server (which has been working for a few years now) recently asked me in a full-screen prompt while updating something about GRUB. There was a list of partitions with just one element, which is the partition that GRUB os on. I was focused on something else so I just hit enter, but now I am really scared to reboot it. Is there any way to pull this back up or to double-check that everything is ok with the machine?

From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

I've got one progam that I need for work that I cannot get to run on Linux. I've tried WINE on both Ubuntu and Zorin (and winlator for android). I have the installer exe file and try to launch with WINE but then nothing happens. Is that a program problem, WINE limitation, or something else? Is there a different program I should try to launch it?

I got one!
What constrains access to an rpc socket in the file system? Is it just the permissions of the socket or is there more to the whole process?
E: I originally wrote port instead of socket because it was early lol.

Howdy. I have a "homeserver" that I'd like to actually start using. What's currently keeping me from it are... Permissions.
I have TrueNas Scale running on top of Proxmox, and I can't for the life of me not access NFS Shares from other VMs (specifically a Debian VM that I use as Docker Host) that I host in Proxmox. Plox hlp.

Is it that much better to have a Desktoo Environment, on my desktop computer? I'm still halving it with Windows trying to get my games to run on arch lol
Can you elaborate on the issue you are having? Having a desktop environment is usually necessary to run games.
I tried running i3, using the arch wiki for the nvidia package. It suggested just the 'nvidia' package for a 2080 TI. Launched steam with proton (forget the newest version at the time it was like last month). Nothing would happen when launching any game. Probably doing a lot wrong or something, sorry if this isn't enough info. I did no logging.

I want to upgrade (Mint 21.3 => 22). Last upgrade took hours and the result was so bad I had to reinstall Mint from scratch. Do you guys use the upgrade tool, or do you have good advice on how to approach this?

I have a server that has multiple services running under multiple users that each store data. I want to be able to bundle all this data up and send it to another server for backups.
At a high level, how do I manage permissions for this? Currently I run the backup as root, then chown it to a special backups user which can log in through ssh. But this all feels clunky to me.
There are many ways to do this, but the next up from users is using groups!
For each file or data directory, create a group that owns it. This group should have the service's user as member. Then create a user for running the backups, and add it to all these groups.
The benefit of this is you don't have to use root, and you have an association of directory to group that you can always change. You can for example grant a user access to a data directory by just adding it to its group.
Might want to take a look at a dedicated backup tool like Borg. It will keep all the proper permissions and file attributes in the backup.
