idk how i would define difficult, but the thing i probably put the most time into figuring out thus far is LXC containers.

Or LXC, if you like not using redundant acronyms. Those containers are good shit, weird shit, but good shit nonetheless.

A recent one:

/var was almost full and I ran pacman -Syu and left the comp to go and make dinner. This was also at the time Plasma 6 was rolling out.

It was a big upgrade along with a new kernel. Download seemed to go smoothly, but during installation, it didn't have enough space to unpack stuff and there was no kernel available to boot. Even the "previous kernel" options didn't work.

It wasn't too hard to fix because I had learnt how to use pacman in a chroot env, but my dinner got cold by the time I was ready to eat.

I still haven't learnt the lesson though. This is the third time I am having a problem with paccache and I still haven't setup a removal daemon/cron job.

My mint install won't let sound through my sound card. Drivers are there, it knows exactly the brand and model of card and shows it, it even knows when I plug/unplug stuff from it, but 0 sound, ever.

The solution?

Just plug my headphones into my new speakers that have their own DAC, anyway.

Still no idea why the card doesn't work right

Fixing Grub issues when I was first starting out.

is debootstrap considered reinstalling? because i'vedebootstrapped at least 2 systems to fix botched upgrades.

It's been a long time but generally network issues and reinstalling bootloaders or kernels. Fairly easy if you can chroot.

Using Linux on a GTX660 without proprietary drivers. I never managed to succeed. Desktop would always freeze. Never again.

Not fixed but there is an Arch problem that is and will always be the bane of mi existence.

For some reason when I click with the trackpad buttons the touchpad gets frozen for like a second (it's like they are recognised by the system as keyboard buttons, I have enabled that option to temporarily disable it when using keyboard).

I've checked for hours and days the libinput documentation and some synaptics libraries, even legacy ones. It is to this day the only problem that has lead me to reinstall my system but the problem remains.

It's not even like I have some niche setup, I mean, surely there must be thousands of Arch users running with a ThinkPad X1 Carbon Gen 7, and surely not every single one of them must be running it like this, right?

It has come to a point where I just gave up and got used to my system as is, but I'm sure I would be running fanfare if some day I am able to fix it.

my session manager refused to start, and I was very close to reinstalling my system.

I used to main Gentoo.

Breaking the install was more of a guarantee.

I once removed most of X by trying to remove Gnome dependencies and it lead to an interesting couple of hours but I did have a working system when I was done.

There were countless dependency bugs and broken systems but at least I learned how to use the Gentoo Forum and also a lot of how Linux works.

I kind of want to give it another go.

I was trying to setup Timeshift for system snapshots on a work computer with Ubuntu. It didn’t work for some reason so I tried to first get rid of it. After uninstalling it, I wanted to remove, what I though, were remains of TS files in /run/timeshift, but the root partition was still mounted, so I rm-rfd the whole root, luckily except for home. And the computer has BIOS password with secure boot, so talking to IT dep about what I’ve done that is…. Or is it? The /boot and the initramfs was still in place, so it was dropping me to emergency shell when trying to boot. Connecting external USB to see if I can mount it, hmm doesn’t show up. Quick search on my private computer what kernel modules are required for USB storage, modprobed couple of xhci_* and bang, was able to mount it. I saved result of ls -l /dev/disk/by-uuid on the drive and moved to my private PC, where I created VM and installed exact same Ubuntu with exact config (LVM+Luks) and after it was done I copied all of / content to the (now formatted as ext4) external drive using cp -a, then edited fstab and crypttab to put proper UUIDs there, set up hostname and user account accordingly. Then moved back to the borked laptop, copied the newly installed Ubuntu back to the root partition, rebooted and it worked perfectly on first try and continues to work. All of that roller coster in just a single hour.

For me it was migrating my Arch install from EXT4 to ZFS. GRUB had to be configured in particular ways to get it to work with ZFS and I didn't do it properly so it wouldn't/couldn't boot.

Then I updated ZFS to a version that wasn't supported by GRUB yet so I chrooted into my installation to switch to Systemd-boot with Unified Kernel Images. Now I still can't figure out how to add a boot entry for Windows. I followed the proper steps I think but selecting the Windows entry just reloads Systemd-boot.

Installed fedora on btrfs and upgraded from 38 to 39 week after installation, everything broke so bad, even ssd which was used for it locked, not just filesystem, ssd was new btw

I recently managed to recover from a corrupted libstdc .so. Turns out I shouldn't have bothered because the it was a Pi and, of course, the SD card had shit the bed, but I was pretty happy with myself for like 30 minutes.

Some of the crap I had to do back in the late 00s to get wifi, sleep and power management even barely working on some machines felt like the hardest thing at the time. I wonder how I’d fare with those issues today, 17 years later, knowing quite a bit more about the underlying OS and working with the OS daily… I don’t know that I’d qualify that as difficult more than it was extremely tedious and a bunch of trial and error of configuration options I didn’t know anything about.

If we’re talking about modern day… not so much honestly. btrfs snapshots saved my ass a couple of times, the rare issue I encounter I just rollback and wait for an upstream fix, and the rest I typically ignore or use something else. Everything tends to run quite smooth for me as a general rule, though.

I managed a CentOS system where someone accidentally deleted everything from /usr, so no lib64, and no bin. I didn't have a way to get proper files at the time, so I hooked the drive up to my Arch system, made sure glibc matched, and copied yum and other tools from Arch.

Booted the system, reinstalled a whole lot of yum packages, and... the thing still worked.

That's almost equivalent to a reinstall, though. As a broke college student, I had a laptop with a loose drive, that would fall out very easily. I set it up to load a few crucial things into a ramdisk at boot, so that I could browse the web and take notes even if the drive was disconnected, and it would still load images and things. I could pull the cover off and push the drive back in place to save files, but doing that every time I had class got really tiring, so I wanted it to run a little like a live system.

I don't know how I fixed it, but KDE Plasma 5.whatever on MX was acting up. It would let me login but if I couldn't do much else. Wouldn't respond to my clicks or anything. Thankfully I could open Yakuake and install a different desktop environment. Then, one day while I was backing up files to do a reinstall, it started working again. I could use Plasma without issues. I have no clue what fixed it, though.

It also came with a non-issue of now my laptop won't auto turn on every time I open it up, but I'll take that over having to reinstall and set things back up.

Rescuing home partition from ZFS, actually that doesn't really count since I did have to reinstall (was no longer booting), but recovering the Home partition from ZFS and to the other ext4 drive was much harder than it should've been and that's why I would never recommend people use ZFS.

Accidentally put grub on the wrong partition on the device, which it was not happy with. Was able to copy some files over, manually boot the OS, and reconfigure grub to be in the right partition, took me about 2 hours? Then I did it again on a different machine, and speedran it lol
