Manjaro doesn't show up

[Soggot]

Hi everyone,
I’m having an issue with my Manjaro system. I cleared the cache, and after rebooting, my system seems to have disappeared. When I check with lsblk, it shows that the system is still installed. I tried reinstalling the GRUB menu using a live USB, but it didn’t solve the problem. After every reboot, I just get the GRUB menu, and Manjaro doesn’t show up. Any advice on how to fix this?

I just ran these three commands:
rm -rf ~/.cache/thumbnails/*
sudo pacman -Qtdq | sudo pacman -Rns
sudo pacman -Scc

After rebooting, everything went to hell. Nothing works anymore — all I see is the GRUB menu, and that’s it.

From Live USB, chroot with command manjaro-chroot -a
Then update the system with command pacman -Syu
Then rebuild the kernel images mkinitcpio -P && update-grub
Maybe install a new kernel too with command mhwd-kernel -i linux612 for Linux 6.12 for example

Exit the chroot with command exit

Reboot to your Grub and see if you can boot.

PS: sudo pacman -Qtdq | sudo pacman -Rns is a recipe for disaster if you don’t look what will happen before it executes the second part of the command. If there is an issue with orphans it will remove everything even if it breaks the system (it happened I have seen it where the package manager wanted to remove most of my packages because they were considered ‘orphans’). Look into your pacman log to see what happened in your system, at /var/log/pacman.log

I cleared the cache, and after …

@Soggot

rm -rf ~/.cache/thumbnails/*
sudo pacman -Scc

These are clearing the cache

@Soggot

sudo pacman -Qtdq | sudo pacman -Rns

That is not clearing the cache !

This way you remove some packages !

You can show what you removed, when you look into the logfile at /var/log/pacman.log . Please show us what you did, so we can suggest, how to undo it:

cat /var/log/pacman.log |grep -E '2025-01-05'    

or if you did it 2025-01-04:

cat /var/log/pacman.log |grep -E '2025-01-04'    

Be careful whose advice you follow. You should understand exactly what the commands do. Otherwise someone might give you the tip to delete the partition table.

I cleared the cache, and after rebooting

Did you mean after updating? It could be that you ignored changing to another still supported kernel after the previously used is no longer in the repos…

In this case you need to install another kernel, e.g. 6.12. So, boot into a live ISO, Manjaro-chroot and install another (ideally 6.12. or LTS) kernel.

Seems like some of the orphans you uninstalled wasn’t that orphaned after all. I bet on a kernel. See what Omano wrote, that should solve it if i am right.

[Soggot]

@omano Thank you so much, you really helped! After the update, everything started working, and there was no data loss. Thanks again!

@Teo Yeah, I just updated the kernel, and everything worked — the system is back without any data loss. Thanks a lot

@Wollie Yeah, the issue was with the kernel. Thank you so much for the advice — it really helped!

Yeah, it wasn’t just about clearing the cache — I also removed some dependencies, which caused everything to break. The guys here suggested updating the kernel, and it actually worked. Huge thanks to everyone!

The suggestion was to install a working kernel.
As well as sync/update in general, but that wouldnt replace missing packages.

In the future, please make use of quotes instead of creating multiple posts.

PS.

The kernel may have been one of the missing packages, but there may have been more. You should probably check your logs via something like

grep -i removed /var/log/pacman.log
