I had a problem, when I tried to install FIND3 with the openhabian-config menu (optional components → FIND3).
The tool couldn’t be installed and threw this error window: There was an error or interruption during the execution of: 20 | Optional Components Please try again
In the console it showed this error information: Installing required packages for FIND3... FAILED (cython)
To solve this error, I changed the directory to “/opt/find3/server/main” and run this command: go build -o find3server -v by msyself. That worked fine for me.
After that go back to your home directory and restart the installation with the help of openhabian-config tool.
I hope it helped some people and saved some time
Sooo, but now I have a problem where I don’t know what to do:
This time the error message is: Adding FIND3 to zram... FAILED (sed)
It’s the error in the find.bash file at line 91 to 96. Unfortunaly I don’t understand that…
Does anybody has an idea what I could try to get it running?
I’m working at OpenHAB 3.1.0.M3 on a RaspberryPi Model 3b
Please don’t discuss in tutorial threads. I moved your post.
Let us know the openHABian branch and version. And do you use OH2 or 3 ?
Read the debug guide. Set debugmode=maximum in openhabian.conf, retry, record the output and paste it here.
I’m using OpenHAB 3.1.0.M3 - Milestone Build. With a Raspberry Pi Model 3b+.
That’s the output from the debug:

I think that’s the interesting part.
The problem is that the file /tmp/ztab doesn’t exist.
In the openhabian-config I can choose in the menu point 38 to use zram. As I’m trying this, it is showing me an error window and in the debug-output it says this:
+ local 'introText=You are about to activate the zram feature.\nBe aware you do this at your own risk of data loss.\nPlease check out the "zram status" thread at https://community.openhab.org/t/zram-status/80996 before proceeding.'
+ local 'lowMemText=Your system has less than 1 GB of RAM. It is definitely NOT recommended to run zram (AND openHAB) on your box. If you proceed now you will do so at your own risk!'
+ local zramInstallLocation=/opt/zram

ZRAM is already installed but it isn’t recommended on my System because I have less than 1 GB.
Or should I uninstall zram and install it again in the hope it works after that? I already made a full backup.
Or is simply my RAM (1 GB) to low to get openHAB and FIND3 running?
in the openhabian-config main menu, right about menu entry 0, there is a headline telling you the exact version which is installed. You can see the branch in brackets that is used plus a date and time in braces plus a part of the .github version’ in braces.
