Permission Denied Error with v4.2.0

[Timurling]

Hello Community,

I got stuck with an error after moving my docker container from version 4.0.0 to version 4.2.0.
Librebooking does not start but gives me this error:

sed: couldn't open temporary file /config/sedRqNvGz: Permission denied

When moving back to version 4.0.0 everything works fine.

Any ideas what is causing this an what I can do to fix it? Did I miss something?

Thanks for your support!

Could you please share your docker-compose.yml file?
Please hide passwords, if any

@colisee` thanks for looking at my issue. Here is the docker-compose.yml.

The change I made was

Could you please share the output of docker compose logs librebookingweb up to the point where sed fails? I am intrigued by the file /config/sedRqNvGz …

could you also share the output of ls -l /home/docker/librebooking/lb1_conf on your host?

I simulated on my side (without traefik though) and I could not reproduce your error.

However, there seems to be a difference between your log and mine.
This is what I have around the sed error:

app-1  | + '[' -f /config/config.php ']'
app-1  | + '[' -f /var/www/html/config/config.php ']'
app-1  | + ln -s /config/config.php /var/www/html/config/config.php
app-1  | + sed -i /config/config.php -e 's:\(\['\''database'\''\]\['\''user'\''\].*\) '\''.*'\'':\1 '\''lb_user'\'':' -e 's:\(\['\''database'\''\]\['\''password'\''\].*\) '\''.*'\'':\1 '\''wordPass'\'':' -e 's:\(\['\''database'\''\]\['\''name'\''\].*\) '\''.*'\'':\1 '\''librebooking'\'':' -e 's:\(\['\''install.password'\''\].*\) '\''.*'\'':\1 '\''wordPass'\'':' -e 's:\(\['\''default.timezone'\''\].*\) '\''.*'\'':\1 '\''Europe/Zurich'\'':' -e 's:\(\['\''database'\''\]\['\''hostspec'\''\].*\) '\''.*'\'':\1 '\''db'\'':' -e 's:\(\['\''logging'\''\]\['\''folder'\''\].*\) '\''.*'\'':\1 '\''/var/log/librebooking'\'':' -e 's:\(\['\''logging'\''\]\['\''level'\''\].*\) '\''.*'\'':\1 '\''DEBUG'\'':' -e 's:\(\['\''logging'\''\]\['\''sql'\''\].*\) '\''.*'\'':\1 '\''false'\'':'
app-1  | ++ find /var/www/html/plugins -type f -name '*dist*'

In my case, I have an additional instruction, compared to you:

ln -s /config/config.php /var/www/html/config/config.php

Given that I might have pushed different versions of librebooking/librebooking:4.2.0, could you please run:

docker compose down
docker compose pull librebookingweb
docker compose up --detach

[colisee]

On top of the above, could you also run:

docker compose exec librebookingweb ls -l /var/www/html/config

[Timurling]

@colisee

I have pulled both images v 4.2.0 and v 4.0.0 which was a bad idea.

Version 4.2.0:
docker exec librebooking_prod-librebookingweb-1 ls -l /var/www/html/config Error response from daemon: Container 63e4aa14deca42899c18c0d0b6abb972e23dae39aab6c5ca6bdff101b8cca1d3 is restarting, wait until the container is running

Since I have repulled the 4.0.0 image I get the same error "sed" there. Which is really bad...

This is the out put of docker compose exec librebookingweb ls -l /var/www/html/config for v 4.0.0 before I have pulled the image again:

-rw-r--r-- 1 www-data www-data 260 Aug 6 2025 config.devel.php
-rw-r--r-- 1 www-data www-data 26782 Aug 6 2025 config.dist.php

-rw-r--r-- 1 www-data www-data 172 Aug 6 2025 timezones.php

[colisee]

Look at the ownership of /config/config.php…
This is not right.
On my side, it is owned by www-data:www-data

And here is the output of docker compose exec librebookingweb ls -l /config:

-rw-r--r-- 1 www-data www-data  1904 Mar 16 17:31 ActiveDirectory.config.php

[Timurling]

Is it potentially related to this sed issue:

• Noteworthy changes in release 4.8 (2020-01-14) [stable]

** Bug fixes

"sed -i" now creates temporary files with correct umask (limited to u=rwx).
Previously sed would incorrectly set umask on temporary files, resulting
in problems under certain fuse-like file systems.
[bug introduced in sed 4.2.1]

[colisee]

I noted that your docker-compose.yml file is not up-to-date regarding some environment variables. Could you:

1. Create an EMPTY directory /home/docker/librebooking/lb2_conf
2. Change your docker-compose.yml file:
   • Switch your librebooking volume to the above empty directory
   • Use the librebooking/librebooking:4.2.0 image
   • Review the name/value of the environment variables for librebooking, by checking the .examples/docker directory in the https://github.com/librebooking/docker repository
3. Run the application docker compose up --detach and report on the outcome

Hi @colisee,

I followed your suggestion and updated the compose file and created a test enviroment using this path /home/docker/librebookingtest/lb1_conf.

The initialization of config.php did not go well: cp: cannot create regular file '/config/config.php': Permission denied.

Instead of using a bind mount, could you use docker volumes, just to see if we can go past the above error?
Your Dockerfile line becomes:

    volumes:
      - lb1_conf:/config

Just to be sure, delete the lb1_conf volume with docker volume rm lb1_conf

By the way, you can drop the job service: it is buggy at this moment

[Timurling]

With this change it directly hits the sed: couldn't open temporary file /etc/apache2/sites-enabled/sedqnKEws: Permission denied error.

We are making progress, but I don’t understand why you are having so many permission errors…
Which Linux distribution are you running on your host?
Which container technology: docker or podman?

Could you please remove the env variable APP_PATH from your dockerfile, delete the lb1_conf volume again and restart with docker compose up —detach

[Timurling]

The host is a virtual server running on Ubuntu 24.04.4 LTS.
I am using Docker version 29.3.0, build 5927d80

By removing APP_PATH the error goes away and when adding it again the error comes back.
Howerver without APP_PATH I get a BAD GATEWAY 502 when accessing sub.my.domain/mypathtest

[colisee]

Without the APP_PATH variable, you cannot logically use /mypathtest.
And now, let’s move to the docker channel on discord :-;

@Timurling @colisee You might also consider doing some of this on the Discord channel. Maybe a faster resolution. Just a thought.

[colisee]

@Timurling : I didn't see you on discord, but I think I understand what's going on in the meantime...

The container /config directory is mounted to your host directory /home/docker/librebooking_test/lb1_conf. This host directory very likely does not belong to user www-data nor to group root. This means that non-owner users have no writing rights to the directory; henceforth the permission error when trying to copy a file to the container directory /config. This also explains why we have no permission issues when using volumes...

Since you probably don't have the system user www-data (unless you installed a package such as apache2), you have 2 ways to solve your permission issues:

• Grant group ownership of host directory /home/docker/librebooking_test/lb1_conf to root
• Grant write permission of host directory /home/docker/librebooking_test/lb1_conf to all users

Please re-create the EMPTY host directory with one of the above 2 solutions and report the outcome to discord if you still have issues or here if the issue was solved, in order to close the discussion.

I confirnm that this is an issue brought by version 3.0.0 (Nov 30, 2025) of the librebooking docker image.

Please, monitor the librebooking/docker repository
