[SOLVED] Can not recover borgbackup (nerdtools) backup due to "wrong" password

SOLVED:

If you ever get in trouble, because you have special characters in your Passphrase (maybe in combination with a non-english keyboard):

Create a new script with:

#!/bin/sh

export BORG_PASSPHRASE="your_passphrase_with_special_characters"

#any borg command works
borg mount /path/to/repo /path/to/mountpoint

That worked in my case

Long story short,

i used to back up my most important files with a borgbackup script found here: https://www.reddit.com/r/unRAID/comments/e6l4x6/tutorial_borg_rclone_v2_the_best_method_to/

Due to some circumstances (long story) i wanted to recover parts of my backups, so i tried to recover them on another (Ubuntu 22.04 and Ubuntu on WSL) system with borg mount. However, borg asks me for the repo password, which is not accepted. My password is randomly generated and has some special characters which should be ASCII: $ # ^ These characters can be typed in with the keyboard.

I am pretty sure the password is right:

• Recovered my flash backup and compared password in the script with the backed up one - both the same
• Compared the repokey with the one i backed up - both the same

I know the script worked fine, because i had to manually start backups from time to time, because borgbackup did not get installed automatically through nerdtools. So sometimes i started the script manually and some times tested with borg create.

I am thinking of some character encoding issues, that unraid may use a different character encoding or something else, so the password was encoded different when setting up the repository and using the script. Maybe the character ^ makes problems? Because on German keyboards you have to type in ^ with a following keyboard input, otherwise the char does not get printed out on the screen.

Can anybody help me out how i could get access to my backups?
