Booting into Emergency Modus

[MaMicha]

Starting my computer, it runs into Emergency Modus. journalctl -xb shows 2.200 lines, few that might be important:

Kernel command line: .Boot image ...5.15.-x86 ...
Unknown command line parameters: "text noplymouth BOOT_IMAGE=//boot/vmlinuz-5.15..." will be passed to user space
...
PCI INT A not connected
...
fsck failed with exit status 4
... dependency failed for /home

What shall I do?

@MaMicha

Unknown command line parameters: "text noplymouth BOOT_IMAGE=//boot/vmlinuz-5.15..." will be passed to user space
...

Please post the output of:

grep -i GRUB_CMDLINE_LINUX /etc/default/grub

[MaMicha]

Lot of text, hopefully I covered the important part:

GRUB_CMDLINE_LINUX DEFAULT="text apparmor=1 security=apparmor resume=UUID=00000000-999-XXX udev.log_priority=3 noplymouth acpibacklight=none"
GRUB_CMDLINE_LINUX=""

[Yochanan]

You have a typo.

@MaMicha

noplymouth_acpibacklight=none

Should be:

noplymouth acpibacklight=none

[MaMicha]

Sorry, my fault. Corrected above …

[Yochanan]

Did you copy and paste the output? Was the typo in the file or did you type the output manually?

Either way, why are you using text and noplymouth?

[MaMicha]

I typed the output manually. This machine has no internet actually, as it did not boot.

Either way, why are you using text and noplymouth?

No idea, did not modify this for about a year or more …

[Yochanan]

Can you access a TTY? If so, remove text and noplymouth from /etc/default/grub. run sudo update-grub and reboot. One or both of those entries seem to be causing the issue.

If not, boot from a Manjaro ISO and chroot in to your system and do it from there.

[MaMicha]

How to access a TTY? Actually I have root access …
Im running nano /etc/defaullt/grub right now

[Yochanan]

@MaMicha

How to access a TTY?

What is TTY in Linux?

@MaMicha

I have root access …

What does that mean, exactly?

[MaMicha]

@Yochanan

@MaMicha

I have root access …

What does that mean, exactly?

I’m in console and did

# cd etc/default
# nano grub

saved the file “grub” after removing “text” and “noplymouth” and did
# sudo update grub
This produced few lines, the last one
/usr/bin/grub-probe: Warning: Unknown device type nvme0n1
Shall I try to reboot?

[Yochanan]

@MaMicha

/usr/bin/grub-probe: Warning: Unknown device type nvme0n1

That’s normal and can be ignored.

@MaMicha

Shall I try to reboot?

Only one way to find out if the changes made any difference.

[MaMicha]

Done, but as far as I can see, the same picture:

Dependency failed for /home
Dependency failed for /home/nn/VirtualBoxVMs
Dependency failed for Local File System

Little bits and pieces of the log isn’t going to help us help you. Please see:

[HowTo] Find error logs

Difficulty: ★☆☆☆☆ The first step for troubleshooting an issue is to find an error log: a trace produced by an application when failing/crashing, and providing the first trail a user/developer can follow to fix it. 1. Reach a usable system Obviously, it will be impossible to acquire those logs if you can’t have access to a usable system. See: [HowTo] Reach a minimal system 2.

@MaMicha

BOOT_IMAGE=//boot/vmlinuz-5.15

Is that // also a typo ?

Welcome to Manjaro!

[MaMicha]

I can run
journalctl --boot=-1 --priority=3 --catalog --no-pager
this shows issues for four device(s) /dev/disk/by-uuid… If there is a way to save this output (almost full screen) I will upload it here.

My Data-Device is /mnt/Daten. I can cd this and it shows all the files. Also I see the file f.e. in /var, /opt, /etc. Then I did

# cd /home
# ls

and it is empty.
Sorry, I’m dead for today and will follow up tomorrow …

[andreas85]

Did you change /etc/fstab ?

[MaMicha]

@andreas85

Did you change /etc/fstab ?

No, but I double checked it now:

# cd /etc
# ls fstabb -l
-rw-r--r-- 1 root root 2854 05. May 2021 fstab
#

What can I do? I have a recent rsync backup for /home on an external USB-HDD; actuallly looks like this:

# cd /home
# ls -laR
.:
total 12
drwr-xr-x  2 root root 4096 7. Nov. 2020
drwr-xr-x 18 root root 4096 3. Nov. 10:27

Is it worth to copy it back? If so, how can I get the drive connected to tje system in emergencý mode?
I also have a timeshift backup:

# sudo timeshift --restore
...
7 > 2022-12-28 18-00-01 D

[brahma]

restore the timeshift …
or boot into manjaro usb, chroot, and compare uuids in
cat /etc/fstab
and
blkid
the ones in fstab should match the ones in blkid

[MaMicha]

@brahma

or boot into manjaro usb, chroot, and compare uuids in

This part first:
I booted the System > EmergencyMode > Enter password
So I’m logged in as root in /. I can run cat /etc/fstab and blkid, the outputs look similar with differences: blkid sows timeshift, fstab does not. But I found all UUIDs from fstab in blkid.
Would it be possible, to copy that output to show it here?
