Hello everybody! here's the problem: In my EndeavourOS laptop I had a /swapfile, but couldn't take snapshots with snapper because of it (if I understood correctly). So, I created a 16Gb swap partition using GParted from a live USB. Then, I edited /etc/fstab to remove the line about the swapfile and to add the newly created swap partition:

UUID=506d48e6-1cc0-4136-ba55-6f2f187bcdb1   swap           swap    defaults   0 0
# /swapfile                                   none           swap    sw         0 0

I took the UUID from

$ sudo blkid  
/dev/nvme0n1p3: LABEL="swap" UUID="506d48e6-1cc0-4136-ba55-6f2f187bcdb1" TYPE="swap" PARTLABEL="SWAP" PARTUUID="b4543e4e-4623-4317-99aa-086b0e62836e"
...

if I run sudo swapon -a it gets enabled correctly and it all works fine. The problem however is that when I reboot the machine, it gets stuck in the systemd screen saying "a job is running for /dev/disk/etc..." forever, and the only way I have to log in is to boot from a live USB, modify /efi/loader/entries/somethingverylong.conf to add these kernel options:

systemd.swap=0 noresume

and then reboot, and manually enable the swap.

I'm not understanding very well what's happening here. why is the system stuck if I don't add these parameters? how can I solve it?

thanks in advance!

which systemd unit/target does it get stuck on?

A start job is running for /dev/disk/by-uuid/8c53812d-ba43-45e4-b219-8d3ded8548a5

it's really strange, I just noticed that it's the UUID of... the original swap partition (now gone) the entry is still commented in /etc/fstab:

# UUID=8c53812d-ba43-45e4-b219-8d3ded8548a5 swap             swap    defaults   0 0

is there another place other than /etc/fstab where I should remove it?

thanks for the help!

EDIT: this is the whole output of sudo blkid if needed:

it sounds like it unrelated to /etc/fstab and that there's something in your systemd config that's expecting it.

if you don't have the name of the unit; i think you search through your systemd config in /etc/ to find & disable it. (ie grep -ir $uuid /etc/)

THANK YOU! The grep command you posted showed me that that UUID was still present in /etc/kernel/cmdline as

resume=UUID=8c53812d-ba43-45e4-b219-8d3ded8548a5

I changed it with the new one and run sudo reinstall-kernels, and now it works correctly! thank you very much for your help!

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.
