Since you're using btrfs, there is likely another subfolder under /mnt. ll /mnt will tell you this, but the drive isn't still mounted from the other day. When you're mounting the EFI partition, you're going to want to mount it to that folder, and not /mnt itself (/mnt/root/boot/efi, instead of /mnt/boot/efi) same for the binds (/dev, /proc, /run, etc)

Yup, should be the same release, just using a different token and therefore needs approved separately

Ugh they didn't keep the same oauth flow so I have to get IT to approve it again for Outlook

Oh absolutely, my account has been overwritten (as if that does anything ) and deleted for over a year now.

Took me wayy too long to realize this is just "Randolph"

“While we are making this change to ensure users’ expectations regarding a community’s access do not suddenly change, protest is allowed on Reddit,” writes Nestler. “We want to hear from you when you think Reddit is making decisions that are not in your communities’ best interests. But if a protest crosses the line into harming redditors and Reddit, we’ll step in.”

Yall have very clearly demonstrated that you do not care about the communities best interest, and you have no interest in hearing what we think. Fuck Spez and good riddance to reddit

Could you send me the output of lsblk -no FSTYPE /dev/sda3 and ll /mnt?

Apologies, I think I got a bit ahead of myself in the description.
Once you've determined which partition is which (in your case, /dev/sda1 does appear to be the EFI partition, and /dev/sda3 appears to be your root partition), you need to mount them in this order

mount /dev/sda3 /mnt
mount /dev/sda1 /mnt/boot/efi

That's alright, I'll do my best to walk you through it.

Your drive contains multiple partitions (/dev/sda1 through /dev/sda3).
One of these drives is going to be your EFI partition. This is what your system can read before linux boots, your BIOS can't understand ext4 / btrfs / etc, but it can understand fat32.
If you run lsblk -no FSTYPE /dev/sda1 it should return vfat if that's your EFI partition. That's what we're going to mount to /mnt/boot/efi

I'm assuming that /dev/sda3 is your data partition, e.g. where your linux install is. You can find the filesystem format the same way as your EFI partition. Edit: After determining which partition is which, you're going to want to mount the root partition, and then the EFI partition
mount /dev/sda3 /mnt
mount /dev/sda1 /mnt/boot/efi

Unix systems have theology of "everything is a file", all devices and system interfaces are mounted as files. As such, to be able to properly chroot into an offline install, we need to make binds from our running system to the offline system. That's what's achieved by running for i in /dev /dev/pts /proc /sys /run; do sudo mount -B $i /mnt$i; done
This is just a simple loop that mounts /dev, /dev/pts, /proc, /sys, and /run to your offline install. You're going to want to either add /sys/firmware/efi/efivars to that list, or mount it (with -B, which is shorthand for --bind, not a normal mount).

Once you've done this, you should be able to successfully chroot into /mnt (or /mnt/root if running btrfs)
At this point, you should be able to run your grub repair commands.

I'm doing my morning scroll before I start my day, so I can't delve too deep, but this is the article I always reference when I have to do repairs

#1 thing I noticed in your image is that lsblk only shows you partitions, and doesn't mount them. You probably want /dev/sda3 mounted at /mnt

The only thing from the article you want to modify is using mount -B /sys/firmware/efi/efivars /mnt/sys/efi/efivars, I believe the functionality changed since that article was written and that's what worked for me

Additionally, if you drive is formatted as btrfs instead of ext4, once you mount your drive your root will most likely be at /mnt/admin or similar. Mount subdirectories to that folder instead of /mnt

If you have questions lmk and I'll get back to you at some point today

I'd go out of my way to make that 8 shrimp just for shits and giggles

I recognized the skeleton before I even saw the post title

No, that was one of our main books. This was something pretty obscure, I've never seen anyone mention it and I don't really remember any more details than that off the top of my head

I was behind in my literature class in like, 7th grade. The books were boring as hell and I couldn't make myself read the chapters at night.

Our teacher gave us a list of bonus titles to catch up for like, 1.5x the points of a normal book, so I jumped on the first one on the list.

I don't remember the title of the book unfortunately, but about one or two chapters or so, the either the main character or their neighbor or something...

Proceeded to put the book down and hand it back into the teacher and ask for a different one. I don't think she was aware of the content of the book

SFC has worked numerous times for me, usually for botched updates. Haven't used it in a long time after leaving tech support

Common misconception; someone prayed that your car would stay broken first and He's gotta honor "first come first served"

This got me to finally move away from Edge. Only thing I'm wishing comes soon is native PWA support. The addon is so janky and my biggest gripe about using Firefox, but I can put up with it since I've now got vertical tabs and multiple profiles

Until then, Mr Parihar wore a bike helmet while driving to avoid more fines.
