🐛 [Nextcloud] latest upstream version does not allow to install apps

[dafunkydan]

Description

I can't enable the External Storage Support App in Nextcloud. When trying to enable it, it says:
Error: This app cannot be enabled because it makes the server unstable

I set the Share up as CIFS networkdisks in the Addon Options and rebooted, it looks like sucessful:

[09:22:50] INFO: ...... //192.168.xxx.xxx/SERVER/SHARE1/Subfolder successfully mounted to /mnt/Subfolder with options rw,file_mode=0775,dir_mode=0775,username=user-smb-nextcloud,password=XXXXXXXXXX,nobrl,uid=1000,gid=1000,iocharset=utf8

Any Idea how to resolve that Issue?

Reproduction steps

1. Set up CIFS Share
2. Reboot the Nextcloud-Addon
3. Open the Nextcloud UI, navigate to Apps-> Find "External Storage Support"
4. Click on "Enable"

Hi, I see the same issue on my instance but I think it is more due to nextcloud than the addon... Perhaps an incompatibility of version? I think you'd have more chance posting on their forum where they have seemed to have encountered that issue before : https://help.nextcloud.com/t/external-storage-support-cannot-be-enabled/120830

But anyway you don't really need it : you can use the /mnt/Subfolder folder as if it was a native folder - this app is only used if you want to mount the SMB drive from nextcloud

[alexbelgium]

According to this "https://www.reddit.com/r/NextCloud/comments/1bqf8wp/2804_error_this_app_cannot_be_enabled_because_it/" you could enable it manually by running occ app:enable files_external after going in the container using portainer. This link also confirms that it is not linked to the addon, but to the upstream container... Good luck!

[dafunkydan]

Wow, Superfast! Thanks and sorry, i could (no, should!) have looked for the Containers Issues.
But now your Answers lead to more Questions ;-) If i may ask:

you can use the /mnt/Subfolder folder as if it was a native folder

I guess that doesnt work for me, using HAOS and having the Nextcloud Data Folder in /share/nextcloud/ ?
Even if i'd know how to, my /mnt/ appears to be empty.
Did i terribly overlook an Option in Nextcloud to add a custom folder on my HAos to a Nextcloud Users' Files? And how could i sync the Data to be shown (see below)?

I use your Nextcloud-Addon to give all Users at Home a centralized Drop / Pickup Structure. Now, my Scanner uploads Scans via FTP to an SMB-Share on my NAS. Users should be able to grab their Scans with just one Click, which is possible when using the Share-Link from Nextcloud, no matter what Device they use...

you could enable it manually by running occ app:enable files_external after going in the container using portainer.

So i need to wait :-D Or install the Addon Portrainer... mhmm...
While i might get this to work for this Case, i still would need to regulary trigger occ files:scan --path="/to/external/added/files/"
Is there a Way i can run the occ Command via Terminal or similar, so i can add it to my shell_command: in HomeAssistant and Trigger that whenever needed?

Thanks for your great Support and, by the Way, awesome Addon-Collection! Highly Appreciate it :-)

[alexbelgium]

Hello! Indeed if you want to use your external drive it would likely be more preferable that you restart from scratch, and directly use /mnt/subfolder/nextcloud as a data folder. This is how my own system is configured. I don't think nextcloud allows to add additional folders after initial config but I might be wrong...

Another way would be that you could have a script that periodically moves your files. For example, an automation that executes every 30 minutes a cp command so that everytime someone uploads to the folder it gets copied to a folder visible by nextcloud ? Usually I simply use the nextcloud app, which allows uploading directly to the nextcloud folders :-)

To run custom commands I don't think it's easy to do it from a shell_command as those run in the homeassistant container, while you would need to run it in the nextcloud container... The easiest way is to use my autoscript feature, that allows you to manually run commands when the addon starts : https://github.com/alexbelgium/hassio-addons/wiki/Add%E2%80%90ons-feature-:-customisation . As this is injected as addon start, it will also stay there even when updating the addon, which would not be the case if you modify the code directly using portainer. There is then two ways to run it regularly:

• By restarting the addon : What I've done to trigger a backup of my files for example is embed a "cp -rnf /mnt/disk/* /mnt/backupdisk/*" in the startup script of one of my addon, and make an automation to restart this addon nightly. This allows the code to run nightly within the addon.
• By cron : Of course here you would likely prefer a regular trigger, so the best way would be to use this code injection to create a cron job...

Hope this is helpful to you :-)

And thanks for the very kind words and appreciation !

[dafunkydan]

Thank you so much for taking your Time and showing and explaining my Option!
As im still in the Phase of observing how it works with my system, i think ill keep the standard Setup by now. Sooner or later (maybe sooner :-D) ill start from scratch anyway, using a big ssd as storage.

The Hint with autoscript, and Options to run that is superhelpful! Thanks! Will give it a shot during the next Days...

I'll keep that Ticket open in Case something change.
I can just add: I restored the second last Version from an older Homeassistant-Backup. Indeed, with Nextcloud 28.0.3 there is no problem at all, i could add external Folders right away. In case somebody has the same Problems and an older Backup....

Thanks again mate! The only Problem with your great Addon-Collection: Too many Temptations. If id use all interesting ones it's surely screw my RPi... :-D

[alexbelgium]

Well downgrading for the moment is another one I hadn't thought of ;-) Glad it works again for you! Ah ah I see what you mean for the number of addons ; actually I've tried a lot but in the end only have a handful running all the time on my rpi4... But it's surprising how little resources most addons used once they have started!

[dafunkydan]

The easiest way is to use my autoscript feature, that allows you to manually run commands when the addon starts : https://github.com/alexbelgium/hassio-addons/wiki/Add%E2%80%90ons-feature-:-customisation .

I feel really dumb, but could you point me to the right direction / path?
I would love to be able to perform sudo -u abc php occ files:scan --all at startup (and/or probably with a cronjob)
I refrain to post all variants i tried, so i dont spread wrong lines :-p
In the End i suspect i just dont know the correct path and dont know how to get it.
Always either getting Error : /etc/cont-init.d/01-custom_script.sh exiting 1 or it silently runs through, but added files simply dont show up :-(

It would be really awesome if you could give me an example of how to properly let nextcloud rescan during startup!

PS: Really great to know that even with rpi4 the addons dont consume that much! Too bad - now even more tempted for more addons :-D

[alexbelgium]

Hi,

To begin with, I've encoutered the same issue as you regarding the unability to install new apps. After investigating it is confirmed to be an upstream issue : linuxserver/docker-nextcloud#422 . To solve it I've installed portainer, then manually enabled additional apps using for example occ app:enable external for the "external" app

Regarding the usage of startup script, you probably should try with

echo "Scanning files"
sudo -u abc php /app/www/public/occ files:scan --all
echo "This is done !"

In theory it should work :-)

[dafunkydan]

Again, Thank you so much for taking you Time! Although:

In theory it should work :-)

Practice speaks a different Language :-D I tried this command as well before, but without success :-(
Merely by accident i found out the following works for me, when i run it just in Homeassistants Terminal Window:

docker exec addon_db21ed7f_nextcloud_ocr sudo -u abc php /app/www/public/occ files:scan --all

But this need protection mode disabled, so not possible to integrate as shell_command, thus not really practical.
So to me it looks like while booting the addon, either php or that path isnt available already. I tried my Luck with ls and find, but no chance.
Do you have any ideas or advices what i could do?

[alexbelgium]

Mmh that's strange what is the error code? And the exact content of the file including header? Thanks!

I wonder if the code is running before occ is started... If yes then you could try :

#!/usr/bin/with-contenv bashio

# Runs only after initialization done
# shellcheck disable=SC2128
if [ ! -f /app/www/public/occ ]; then cp /etc/cont-init.d/"$(basename "${BASH_SOURCE}")" /scripts/ && exit 0; fi

echo "Scanning files"
sudo -u abc php /app/www/public/occ files:scan --all
echo "This is done !"

[dafunkydan]

I wonder if the code is running before occ is started

Based on my very little no none knowledge, i have the feeling it running way too early.
What i tried via addons_autoscripts\nextcloud-ocr.sh, and what i got in log when Restarting the Addon:

• sudo -u abc php /app/www/public/occ files:scan --all
  Could not open input file: /app/www/public/occ
  Error : /etc/cont-init.d/01-custom_script.sh exiting 1
• ls /app/www/public/
  ls: cannot access '/app/www/public/': No such file or directory
  Error : /etc/cont-init.d/01-custom_script.sh exiting 2
• ls /app/www/
  src
• if [ ! -f /app/www/public/occ ]; then cp /etc/cont-init.d/"$(basename "${BASH_SOURCE}")" /scripts/ && exit 0; fi
  cp: cannot stat '/etc/cont-init.d/nextcloud-ocr.sh': No such file or directory

[alexbelgium]

Hi, sorry I wrote that code from my couch without testing it :-) Here is a code tested as working :

#!/usr/bin/with-contenv bashio
# shellcheck shell=bash

#################
# CODE INJECTOR #
#################

# Any commands written in this bash script will be executed at addon start
# See guide here : https://github.com/alexbelgium/hassio-addons/wiki/Add%E2%80%90ons-feature-:-customisation

# Runs only after initialization done
# shellcheck disable=SC2128
mkdir -p /scripts
if [ ! -f /app/www/public/occ ]; then cp /config/addons_autoscripts/"$(basename "${BASH_SOURCE}")" /scripts/ && exit 0; fi

echo "Scanning files"
sudo -u abc php /app/www/public/occ files:scan --all
echo "This is done !"

[dafunkydan]

Awesome, yes its working Great and instantly!
I wish i would have as much as Knowledge. Thank you so much for helping me out there! 👍 👍
