Docker image: setup warning missing bz2 after update to NC 28.0.0

Hello I upgraded today from Hub 7 to Hub 8 and now Iam getting this:
This instance is missing some recommended PHP modules. For improved performance and better compatibility it is highly recommended to install them: bz2.
Besides the error log message: 6975 errors in the logs since 7. Dezember 2023 but this is apparently a bug right now…

So I have tried the following:
apt-get install php8.2-bz2

Which gives me the following output:
Package php8.2-bz2 is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

E: Package ‘php8.2-bz2’ has no installation candidate

I then tried to follow this guide: How to install/upgrade PHP 8.2 on Debian and Ubuntu systems • PHP.Watch

I ran inside the container:
sudo apt install apt-transport-https lsb-release ca-certificates wget -y
sudo wget -O /etc/apt/trusted.gpg.d/php.gpg https://packages.sury.org/php/apt.gpg
sudo sh -c ‘echo “deb Index of /php/ $(lsb_release -sc) main” > /etc/apt/sources.list.d/php.list’
sudo apt update

apt install php8.2-{bz2}

Nothing did seem to help so any help or suggestions would be appreciated.

Associated Github issue regarding this warning for the Docker container

When using the docker container you can run:

docker compose exec nextcloud_app apt-get update && apt-get install -y libbz2-dev && docker-php-ext-install bz2

and then restart the container

docker compose restart nextcloud_app

I have tried this:

docker exec nextcloud-app-1 apt-get update && apt-get install -y libbz2-dev && docker-php-ext-install bz2

I used docker exec container-name because I created nextcloud as a portainer stack and this command wouldnt work:
docker compose exec nextcloud-app-1 apt-get update && apt-get install -y libbz2-dev && docker-php-ext-install bz2

This is the Output:

Those commands worked for me.

Hello,

As I don’t use compose to run my containers but Ansible, and as inside the container Im user ID 1001 I had to enter the container as root, to be granted to install packages:

docker exec -u 0 -ti nextcloud-app /bin/bash

And then:

apt-get update && apt-get install -y libbz2-dev && docker-php-ext-install bz2

Unfortunately it didn’t solved the warning message. I don’t get the point actually, if we install something inside the container, those changes won’t be kept as we restart the container, maybe we should bind some volume ? Or in the Dockerfile they schould ad some line like:

RUN apt-get update && apt-get install -y libbz2-dev && rm -rf /var/lib/apt/lists/*
RUN docker-php-ext-install bz2

Update I just fired up Nextcloud again and rerun these commands and this time it worked.

apt-get update && apt-get install -y libbz2-dev && docker-php-ext-install bz2

The real question is.
Why is this not a part of the official docker ?

All this is an work around, right ?

There is a discussion about this on GitHub, so if you want to share your reasoning with the devs of the Docker image, that would be the place to do it: After upgrading 28.0.0 bz2 module missing · Issue #2118 · nextcloud/docker · GitHub

That beeing said, according to this comment it seems that this module is not actually used by anything, or at least not by any of the the standard Nextcloud apps. So unless you’re experiencing any issues or a specific app explicitly requires bz2, its probably save to ignore the warning, at least for the time beeing.

Please also note that the Nextcloud Docker Images are a community project maintained by volunteers, which means that you are not entitled to any kind of support or the implementation of your feature requests. So please be nice if any of you decides to join the discussion over there… :slight_smile:

you might be right technically right regarding bz2 usage but setup warnings are core elements and don’t come from the docker project - this one is not to blame and only must adopt the new requirements - btw the “community” Docker project is hosted inside of Github organization “Nextcloud” and must be considered as “official”

11

I just summarised what I took away from the discussion in the linked GitHub issue, and maybe it will help some people sleep better, knowing that their Nextcloud won’t explode because of this warning… :wink:

If they had asked me, I would have said: Just install the darn package and ship it with the next release! But they didn’t ask… :wink:

thanks. this fix worked on nc 28.0.1

i had to run the command this way:

docker exec -it nextcloud-app-1 bash

and then:

apt-get update && apt-get install -y libbz2-dev && docker-php-ext-install bz2

specify the full pathname of the library, or use the `-LLIBDIR'

   - add LIBDIR to the `LD_LIBRARY_PATH' environment variable
     during execution
   - add LIBDIR to the `LD_RUN_PATH' environment variable
     during linking
   - use the `-Wl,--rpath -Wl,LIBDIR' linker flag
   - have your system administrator add LIBDIR to `/etc/ld.so.conf'

How could you do it in a permanent way? As soon when the container is recreated, bz2 disappears.

14

I’m getting rid of NC on Truenas because of stuff like this. Workaround guides for problems are always for docker images or native installs, which are a bit different for Truenas installs and I dont have the expertise to figure out what the difference needs to be.

I will make an SMB share with my folders on it, and let NC use that as the datastore. That way NC just runs on Debian and that’s that. No docker, nothing hard to manage.

15

You would need to create a Dockerfile and delcare the nextcloud image, your custom commands and, then build a customized image using said Dockerfile

That said there looks to be little point as the warning is the only new thing and may be removed in the future as nothing actually uses bz2

The advice from the GitHub issue is that this warning can safely be ignored at this time

Hello,

I tried to run the commands you specify but I got errors because bash executes just the first command in docker compose and the rest on the bash session itself.

So I had to use these commands separately:

docker compose exec app apt update
docker compose exec app apt-get install -y libbz2-dev
docker compose exec app docker-php-ext-install bz2
docker compose restart

*Being app the name of the docker service corresponding to Nextcloud instance.

Also, everytime you update the docker image you’ll need to install this module, so if you don’t want to make a Dockerfile to include it, you can make a script (that’s what I did) to manually run after an update.

 #!/bin/bash
dcpath='/root/docker-apps/nextcloud/docker-compose.yml'
app='nextcloud-app'

/usr/bin/docker compose -f $dcpath exec -u 0 $app apt update
/usr/bin/docker compose -f $dcpath exec -u 0 $app apt-get install -y libbz2-dev
/usr/bin/docker compose -f $dcpath exec -u 0 $app docker-php-ext-install bz2
/usr/bin/docker compose -f $dcpath restart

Remember to change the dcpath and app variables to suit your setup.

Thank you for your help, @dugite-code!
Mauricio

Is there a reason why isn’t this installed by default inside the docker image? The changes are gone after the container down&up …

The bz2 check is slated for removal in the next point release. As it turns out it isn’t required for anything. [stable28] Remove disputed bz2 check by backportbot[bot] · Pull Request #43013 · nextcloud/server · GitHub
