I just did a fresh Openhabian install of openHAB 2.5.0-1 on a Raspberry Pi3 with Raspbian Buster. Java Zulu22.214.171.124-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.
