Platform information:  
Hardware: Raspberry Pi4 4GB SD:32GB  
Openhabian 1.6-alpha (openhabian-pi-raspios32-202201271414-git08bc4ff-crcdd86375a.img.xz)  
Decided to move from OH2.5 to OH3 - seems that a fresh install would be the best way to go, but ran into a problem.

I encountered this problem so started over a second time with the same result.

- Flashed the zip file onto a brand new sanDisk micro SD
- No modifications made to the flashed card
- Inserted into the Pi4 connected to my router via cable
- and started the Pi4
- Install seems to have been successful except for the ZRAM.

openHABIP:8080 up and running: create a login page  
openHAB log viewer also up and running

I tried several times used openhabian-config to enable ZRAM:  
select 30 (system settings)  
select 38 (use ZRAM)  
but it results in error:

```auto

```

and the command line on exiting openHABian config says:

```

So it appears that zram can’t be enabled because of something to do with logrotate.

With the openHABian logging set to maximum, I get this further information (I have the complete log but its rather long to include here unless its needed):

```auto

+ [[-n '']]
+ echo -e '\n\033[90;01m$ mkdir -p /usr/local/share/zram-config/log \033[39;49;00m'

```

```auto

```

Any help with where to go from here, pretty sure I can’t just create the missing directory?

Missing directory ?  
The command

```auto
install -m 644 /opt/zram/zram-config/zram-config.logrotate /etc/logrotate.d/zram-config

```

should install the file zram-config.logrotate as file zram-config in directory /etc/logrotate.d.  
As you do have the target directory the question is do you have the source file ( zram-config ) ?

You mentioned which openhabian image you installed but you did not tell anything about if resent updates for openhabian were installed. Version information can be found on the dialogbox header.

Thanks for getting back to me Wolfgang\_S 😀

> [@Wolfgang\_S](#):

> Version information can be found on the dialogbox header.

Did you mean this data from the SSH terminal:

```auto
Linux openhabian 5.10.92-v7l+ #1514 SMP Mon Jan 17 17:38:03 GMT 2022 armv7l
openHAB 3.2.0 - Release Build

```

or perhaps this from the openhabian config tool

```auto
openHABian Configuration Tool — [openHAB3]{2022-01-28T11:18:18+01:00}(aaf8aca)

```

I have since run menu 10 | Apply improvements,  
sub menu  
11 | Packages  
13 | System Tweaks

11 appears to install fine but 13 fails and that looks to be related to zram also  
Tried to enable zram agian still no joy

```auto
+ echo -e '\n\033[90;01m$ systemctl restart zram-config.service \033[39;49;00m'

$ systemctl restart zram-config.service
+ systemctl restart zram-config.service
Failed to restart zram-config.service: Unit zram-config.service not found.
+ return 5
+ echo FAILED
FAILED

```

> [@Wolfgang\_S](#):

Source directory, no: zram-config.logrotate

```auto
openhabian@openhabian:/opt/zram/zram-config $ ls
CONTRIBUTING.md install.bash LICENSE.md overlayfs-tools README.md service tests uninstall.bash update.bash zram-config ztab

```

Thanks for any further help you can give.

I did not dig deeper into the problem.  
@ecdye Is this a problem of openhabian-config ..?  
Looking into github you can find the missing file at [https://raw.githubusercontent.com/ecdye/zram-config/main/service/zram-config.logrotate](https://raw.githubusercontent.com/ecdye/zram-config/main/service/zram-config.logrotate)  
I think you can download the file manually and then try again if enabling works.

</div>

Thanks for your help, getting closer to the problem I feel. 😀  
But I’m still struggling with it.

I’m able to recreate the missing source file:

> Looking into github you can find the missing file at [https://raw.githubusercontent.com/ecdye/zram-config/main/service/zram-config.logrotate](https://raw.githubusercontent.com/ecdye/zram-config/main/service/zram-config.logrotate)

```auto
openhabian@openhabian:/opt/zram/zram-config $ sudo nano zram-config.logrotate

```

And add the file content from the quoted link.  
The file permissions are correct also.

```auto
-rw-r--r-- 1 root root 119 Feb 21 12:06 zram-config.logrotate

```

But when I run the openHABian config tool option 38, I get the exact same error and it appears that the directory is overwritten during the zram install.

I confirmed this by touching another file in the directory and executing option 38 again.

Looking through openHABian config log it appears that the script [https://github.com/ecdye/zram-config](https://github.com/ecdye/zram-config) replaces the directory: mkdir -p /opt/zram and then updates it from the git repository: update\_git\_repo /opt/zram/zram-config openHAB

```auto

$ update_git_repo /opt/zram/zram-config openHAB
+ update_git_repo /opt/zram/zram-config openHAB

```

The content of /opt/zram/zram-config on my Raspi after the failed zram install is:

```auto
openhabian@openhabian:/opt/zram/zram-config $ ls -l
total 64
-rw-r--r-- 1 root root 3593 Feb 19 15:04 CONTRIBUTING.md

-rwxr-xr-x 1 root root 14049 Feb 19 15:04 zram-config
-rw-r--r-- 1 root root 2610 Feb 19 15:04 ztab

```

It looks to me like the zram-config.logrotate is in the wrong directory on the repo and consequently on my RasPi

```auto
openhabian@openhabian:/opt/zram/zram-config/service $ ls -l
total 12
drwxrwxr-x 2 root root 4096 Feb 19 15:04 OpenRC
drwxrwxr-x 2 root root 4096 Feb 19 15:04 SystemD
-rw-r--r-- 1 root root 119 Feb 19 15:04 zram-config.logrotate

```

I also noticed while comparing with another working installation that zram-config.service appears to be missing also.

So I think these needs to be fixed in the repository.  
If that is the next step, I don’t use git / github, so help to raise an issue will be much appreciated.

indeed exactly this was changed in **main** branch.  
Click on the above link and you can see the differences.

Issue should be fixed on the `openHAB3` and `main` branches now. Sorry about that I forgot that I needed to forward the changes in order for the majority of users to have the issue fixed.

Moved onto the openHABian main branch, but  
OpenHABian option 38 only worked after running the uninstall script,

```auto
sudo /opt/zram/zram-config/uninstall.bash

```

due to a problem with stopping the zram-config.service, as it was not running.

```auto
+ echo -n '2022-02-25_12:30:11_CET [openHABian] Updating zram service... '
2022-02-25_12:30:11_CET [openHABian] Updating zram service... + cond_redirect systemctl stop zram-config.service
+ [[-n '']]
+ echo -e '\n\033[90;01m$ systemctl stop zram-config.service \033[39;49;00m'

$ systemctl stop zram-config.service
+ systemctl stop zram-config.service
Failed to stop zram-config.service: Unit zram-config.service not loaded.
+ return 5
+ echo 'FAILED (stop zram)'
FAILED (stop zram)
+ return 1
+ '[' 1 -ne 0 ']'
+ whiptail --msgbox 'There was an error or interruption during the execution of:\n "30 | System Settings"\n\nPlease try again. If the error persists, please read /opt/openhabian/docs/openhabian-DEBUG.md or https://github.com/openhab/openhabian/blob/main/docs/openhabian-DEBUG.md how to proceed.' 14 80

```

All looks to be good now thanks
