I can't login Ubuntun 22.04 on MAC M1

It always said 'Bad password'. I tried 'parallels', 'Parallels', 'ubuntu'.... I tried to finde default password in internet, all I found is password is 'parallels' but it does not work, please help, sorry bad English

 

Pramesh, I have the same issue, but the article you cited above did not work for me. There is no "recovery mode" option for me in the Boot Manager

 

I have the same problem.

M1 Mac mini. Downloaded U22 and it doesn't work as suggested. The shift doesn't work. The ESC failed to bring up the boot order - only showing grub>

 

I'm having the same issue and neither ESC nor shift do anything.

 

It took me eight hours to resolve this issue.

I'm still amazed why parallels doesn't have instructions to solve this problem.

Solution:
1. You have GNU GRUB version 2.06 open.
2. Use the ls command to find in which partition ubuntu itself is located "ls (hd0,msdos1)/ "
3. When you find it you need to load the kernel from that partition. Do the commands one by one:
set root=(hd0,msdos1)
linux /vmlinuz root=/dev/sda1 ro single
initrd /initrd.img
boot
4. After writing boot, the command line will boot with root privileges. In it you need to execute:
mount -o remount,rw /
passwd parallels
5. Enter the new password and confirm again.
6. After the change, reboot the system: reboot

 

Thanks much, Tuntes! That worked!

A few notes for people like me who are unfamiliar with all this:

* To get to GNU GRUB, you may have to go through the "Select boot device on startup" process, then reboot, then Continue, then press Escape a few times. You end up on a page that says something about GNU GRUB at the top, and has a prompt like grub>

* Do `ls` to see what the partitions are. Then to look at a given partition, type (for example) `ls (hd0)/`.

* Ubuntu may be inside a boot directory in the partition. So you may need to type (for example) `ls (hd0,gpt1)/boot/` in order to see the ubuntu directory.

* If Ubuntu is in a boot directory, you need to include that boot directory in the path for the next couple of commands. Like: `linux /boot/vmlinuz root=/dev/sda1 ro single` and `initrd /boot/initrd.img`.

* There are restrictions on what you can set the new password to be. For example, you can't set it to "parallels" or to a string less than 8 characters long.
