NextcloudPi appstore cUrl error 6, can't install anything!

Hi!

I’ve set up Nextcloud 18.0.5 with Nextcloudpi 1.26.2 on Debian 10 (buster) x86_64. The instance is running as a VM in Proxmox.

Almost everything goes smoothly, and I am able to set up letsencrypt / duckdns and upload/download and edit files and all, but things fall apart when I try to install any apps. One error message does show its head in the initial install:

cURL error 6: Could not resolve host: github-production-release-asset-2e65be.s3.amazonaws.com (see http://curl.haxx.se/libcurl/c/libcurl-errors.html)

Any app I try to install via WebUI gives me the same error message, and I suspect the original error message has to do with attempting to install the Calendar app. I’ve tried to wait and see if it is a momentary connection error, but it has persisted for a longer period of time now.

I was able to manually install the applications I wanted previously via CLI, but after a clean install even that seems to have failed as trying to install and enable the apps via OCC gives me the exact same error message once again.

I tried

host github-production-release-asset-2e65be.s3.amazonaws.com

Which said the URL was an alias for s3-1-w.amazonaws.com, which I was able to ping from the nextcloud instance shell, dont know if this info is of any use, but if theres a connection error somehow that confuses me further.

Is there any way to remedy this, or has anybody come across similar issues or a fix?

Here’s the output of my Nextcloud log in Admin > Logging:

Thanks!

The issue persisted even after updating Nextcloud to 18.0.6 in the WebUI.

I tried wget and git clone:ing the Github repos into my /var/www/nextcloud/apps, and enabling them with:

sudo -u www-data php occ app:enable calendar / groupfolders

As I was also unable to even enable them in the WebUI due to the same error message. I was initally able to get them enabled with the OCC command, but the usage was incredibly buggy (webUI blank screen on calendar, group folder icons missing etc.).

I then tried downloading the apps tar.gz from apps.nextcloud.com, rsyncd them via ssh to my nextcloud /var/www/nextcloud/apps folder and extracted them. After this, installing and configuring them via OCC yielded in fully functional installs!

I am still unable to install, or even enable installed apps in the webUI due to the same repeating error message. I tried disabling my firewall or PiHole DNS momentarily to see if I was somehow blocking my own requests, but none of them seemed to help, so I remain stumped, but anyhow here’s a workaround if anyone stumbles upon the identical issue and needs to find a way to resolve it!

I have something like that too

Could not connect to appstore: cURL error 6: Could not resolve host: api.nextcloud.com (see https://curl.haxx.se/libcurl/c/libcurl-errors.html)

Okay! Good to see I’m not alone in this boat.

I just posted my workaround in the above post as I was able to resolve this issue in CLI with the OCC configuration tool.

It was a bit new for me, but it was pretty simple in the end, let me know if you hit any walls and I can try and help and see if we can replicate the workaround :slight_smile:

where is the solution ?

I have the following errors. I can’t download or install anything

does anyone have a solution?

I didn’t solve the resolving issue, so I would love to hear if someone understand it better / has a solution, but my workaround for installing was as follows.

  1. Download the tar.gz file for the app you want to install
  2. Extract it into your /var/www/nextcloud/apps/ directory
  3. cd into your /var/www/nextcloud/ directory
  4. sudo -u www-data php occ app:enable calendar (replace calendar with whatever app you want to install

This worked for me, and I was able to configure the installed apps with occ configuration tool as well.
