Nextcloud Redis errors

capelo · July 2, 2024, 11:25pm

I’ve installed Nextcloud from BigBear, but was having lot of Redis errors.

On Nextcloud log we can see:

(continues...)

On my journey to try to fix the issue, on CasaOS I went to the App Settings, selected the “redis-nextcloud” container and on the network field that was empty, I’ve selected “big-bear-chrome_default”.
Now I cannot unselect it to make the field empty as before and I can’t turn on Nextcloud as it gives an error “Installing big-bear-nextcloudErrorInfo”.

Anyone knows how can I fix this? @dragonfire1119 can you help? Thank you.

Did you remove the network or change it?

I’ve selected one option through the UI.

Now I can change to a different option, but I cannot remove the network as it was by default.

dragonfire1119 · July 3, 2024, 4:03am

The network should be the next cloud network, like on Github, not big-bear-chrome; that’s your issue. You can edit your raw Docker Compose with:

# Network definition for the big-bear-nextcloud application
networks:
  nextcloud_network:
    driver: bridge

In each service it should be:

networks:
      - nextcloud_network

capelo · July 3, 2024, 11:57am

Sorry the dumb question @dragonfire1119 , but how can I edit the raw Docker Compose without uninstalling the current instance? Or can I uninstall and reinstall without losing the contents?

On the options I’ve available on “Network” field there isn’t “nextcloud_network”:

If I select “big-bear-nextcloud_nextcloud_network” I get the following error:

Also, the other services always had the “Network” field empty:

issue. You can edit your raw Docker Compose with:

Video [How to edit CasaOS apps with a Big Bear Script] About Occasionally, the CasaOS container settings UI may not grant us the flexibility to modify configurations as we desire. To address this challenge, we’ve developed a script that simplifies the process: bash -c “$(wget -qLO - https://raw.githubusercontent.com/bigbeartechworld/big-bear-scripts/master/edit-casaos-apps/run.sh)” This script allows you to choose your desired application and select your preferred text editor, cur…

Did you try the script?

capelo · July 3, 2024, 11:39pm

I just tried the script. Followed the how to video, and simply changed the network on the “redis-nextcloud” service to “null” and saved.
It seemed to be a super great way of doing these changes.

Unfortunately, the result was having 4 different services asking to be rebuilt, and cannot use any of them.

@dragonfire1119 do you think there is any way to fix this?

dragonfire1119 · July 4, 2024, 12:43am

The networks in each service should be:

- nextcloud_network

capelo · July 4, 2024, 11:54am

DIdn’t work. Everything continue same way.
I just lost all the configs I already had done. Installed again from the store, had the same issue with redis and tried again the script as per default network is null for everything.
Same result: once I save the script, get the same issue with 4 different services.

dragonfire1119 · July 5, 2024, 3:17pm

I’ve not had that happen. What version of CasaOS are you on? Also what did you change in the docker compose files?

capelo · July 5, 2024, 3:37pm

Latest version - v0.4.9
The only changes on the docker compose file were the ones you said - simply changed the networks from the services to nextcloud_network.

So your networks is “null” in every service, not “nextcloud_network” as advised.

My initial request was exactly to make “redis-nextcloud” container with “null”.
Once I used the script everything messed up. Can it Nano saving it on a wrong way?

dragonfire1119 · July 5, 2024, 4:17pm

This is the way CasaOS formatted it (Sorry I got distracted with work and answering questions.) I was looking in github. It’s different at BigBearCasaOS. You can try to uninstall, but don’t delete user data on uninstall.

Uncheck mark the delete data. You can also backup the AppData before doing so.

I use Nano so should not be a issue.

You can also copy and paste it in there, and it should work, but the best way would be to reinstall the container without deleting your data. /DATA/AppData holds all the data for containers unless changed.

capelo · July 5, 2024, 4:31pm

Tried that. I’m not being able to reinstall.
I deleted all the services related to Nextcloud without deleting the AppData, but it isn’t allowing me to reinstall.

dragonfire1119 · July 5, 2024, 4:32pm

Can you hover over for the full error?

Also, you can install Dozzle and turn it on in the settings for stopped containers.

This would give you more info on what’s happening.
