I strongly recommend not using sshpass unless there is absolutely no other way. Luckily there is a way and it’s not all that difficult. See:
- https://karaf.apache.org/manual/latest/security
- After reinstalling OH2.5M5 on openHABian I now have to provide credentials for running openhab-cli console
The key is stored in a file at /var/lib/openhab2/etc/. Technically we are not supposed to be editing the files in this folder and they are considered system files, not user-space files. But there are some things we just can’t do without changing these files, like changing the Karaf console password. I know that when using Docker, changes to these files are preserved. I’m reasonably sure that when using apt or openHABian to update these files get overwritten and therefore returned to the default.
Note that this is a double edged sword. For example, I had changes made to my logging config that I kept for a long time and more and more junk kept showing up in my openhab.log as new versions came out. Eventually I compared my version with the version in github and there were about 50 new lines added that I was missing.
I don’t think there is a good answer for this except to remember to reapply the changes to the files in /var/lib/openhab/etc after an upgrade.
