Could not download app dokuwikiembedded in nextcloud

[ion-lane]

Hello! Please help me install dokuwikiembedded in nextcloud. I downloaded the app and unpacked it to ../nextcloud/apps/wiki/. Changed the version in info.xml max-version = "20" to 21. Run make. I had to install @ nextcloud / event-bus first.

# npm i -S @nextcloud/event-bus                                                                                                                                                            > core-js@3.12.0 postinstall /var/www/nextcloud/apps/wiki/node_modules/@nextcloud/event-bus/node_modules/core-js> node -e "try{require('./postinstall')}catch(e){}"

Then when I turned this app on nextcloud I got the error:

Hi, I did not try Nextcloud 21 yet, as the context in which I'm using this app is bound to v20 for other reasons.

However, the "download error" you are experience seemingly means that this app-installer tries to download the app from the app-store. This cannot work, as the app is (not yet, or even never) available from the app-store. This is a bit unexpected as you have extracted the app to the app-folder of your Nextcloud instance (at least it seems so?).

Are the permissions of NC-BASE/apps/wiki s.t. the web-server can find the app?

[ion-lane]

The apache user has directory permissions. There is an application in the nextcloud web interface. The occ command shows it too. But when I try to enable it shows:

# sudo -u apache php occ app:list
The process control (PCNTL) extensions are required in case you want to interrupt long running commands - see https://www.php.net/manual/en/book.pcntl.php
Enabled:
  ***
Disabled:
  ***
  - wiki

# sudo -u apache php occ app:enable wiki
The process control (PCNTL) extensions are required in case you want to interrupt long running commands - see https://www.php.net/manual/en/book.pcntl.php
App not found

And when i turn on the application in the web interface, it shows

Exception: Could not download app dokuwikiembedded

I'll try to check this application in NC20.

[rotdrop]

I'm currently trying to install it with a v21 cloud. There is no DokuWiki installed, but at least I can check if the app is installable.

[rotdrop]

Hi, just name the folder like the app-name, i.e. not "wiki", but "dokuwikiembedded". Don't known whether this is/was different or could be configured in another way.

Cheers,

Claus

It works! The application has been installed. Thank you for help.
