Qubes stopped booting, can we find the cause? And how can I recover it?

Recently I was replacing old package list to new release on some machines

I dont use the qubes laptop that often so I am not certain but I think that after that, next time I wanted to turn it on, it won’t start

It asks for the first password and then freezes

I took a screenshot

I am a beginner linux user but I am determined
Please help me rescue it

Could you give us some more details concerning what exactly you were doing? Is this about dom0 packages or Templates? Were you updating from R4.1 to R4.2?

I am not sure what i was doing prrcisely
But I was replacing some words in package list on some machines to make them able to update

I did nothing on dom0 yet

Besides

I dropped the laptop and some hardware might be currupted

Can I run some test to find if all the hardware is running good?

Also my question is
Can i run tails live to decrypt the disc and gain access to my qubes
I would be satisfied if i could have my passwords and my pgp key

Thank you
I need more adivce

Tutorial that you linked wants me to act in dom0 etc and i dont have access to my qubes

I ran live debian from usb and i see my encrypted disk
When i click on it it asks for password but when i enter correct password it says encryption cancelled and encrypted disk icon dissapears

What should i do exactly in live debian console to access my qubes files

the only dom0 mention is about the case you want to mount the file system of a qube into another, which is not your case.

Basically you need to do this in your live system, adapt the disk names to your setup:

cryptsetup luksOpen /dev/sda2 luks-qubes
vgchange -ay

From there, you will have a lot of partitions available in /dev/mapper/ or /dev/lvm/, I do not remember well. You want to look the private partition of your qube name and mount it somewhere in /mnt, you can create /mnt/myqube/ and mount it there.

Okay
I managed to mount partitions that I wanted to mount
Started with
Vm-GPA-private

Now I need some hint on how to run this gpa tool to access my pgp account

Cant find it in any folders

certainly in the home/user directory of the volume, if it’s using GnuPG, it’s in home/user/.gnupg
