Unable to change password in openhabian-config

Setup, Configuration and Use Items & Sitemaps

I just did a fresh Openhabian install of openHAB 2.5.0-1 on a Raspberry Pi3 with Raspbian Buster. Java Zulu8.40.0.178-CA-linux_aarch32hf (build 1.8.0_222-b178)

As soon as the install was done I tried to update the system password using openhabian-config. Entered the default and the new password and it said “:password successfully set for:” This made me suspicious as I have seen this problem before. I checked and the password had not been changed.

I am able to change the system password using the passwd command, and it survives a reboot, so I do not think I have a problem with the SD card.

As mentioned I had this same problem a year ago and was able to fix with “sudo mount -rw -o remount /”. Tried that this time and the command executed but it did not help.

The same problem also applies to changing Samba passwords. I did not check the others.

I was able to complete the setup and openHAB seems to be operating normally but I am concerned that whatever is causing this may be causing other problems as well that I have not noticed yet.

Any suggestions appreciated.

When logged in as your system user you should be able to change that user’s password by using the passwd command. It will prompt for the existing password and then the new one twice.

Hi Bruce. Yes the passwd command works. My question is what is causing the openhabian-config password change process to not work and what else may that be affecting?

4

Not likely anything else affected. There should probably be a GitHub issue filed for @mstormi or one of the other developers to resolve the issue.

Add a “set -x” to the change_password() function in /opt/openhabian/functions/passwords.bash to see what happens.
If I was to guess you ignored that it has to have 10 chars.

Hi Markus. I tested a password less than 10 characters and it would not accept it. Here is the result after adding set -x:

Did you actually select any of the users ? Move cursor and press space I mean ?
Log trace does not look like you did.

Did you manually install openHABian on buster or did you use the Pi image ?

Ha! Stupid user error! I had scrolled the red cursor but did not realize I had to use the space bar to select.

Thanks!
