occ app:install works on and off

[enoch85]

I've got several reports the about failing app installations since I implemented occ app:install in the VM. I've also noticed it myself that apps often fail to install right after installing Nextcloud. Lately I've also got reports that OnlyOffice works if you enable from gui, but not with the occ commands (install and enable). Hence this report.

I can't really give you any steps to reproduce since it happens randomly. My own theory is that it's due to one of three things:

1. The App Store is temporarily overloaded
2. Network is temporarily failing
3. The code for occ app:install is buggy

Could you please give me any guidance on different scenarios to test so that I can give you more accurate steps to reproduce?

GitMate.io thinks possibly related issues are #7563 ([occ] Hide "not installed" info on "occ maintenance:install"), #1947 (Add app installation and update capabilities to occ), #6581 (Theming app (still) not working in NC 12.0.3), #9853 (No route to host when trying to install an app), and #1599 (Install app via command line - occ app:install).

There is a known DNS issue in Ubuntu 18.04 LTS, see https://medium.com/@ahmadb/fixing-dns-issues-in-ubuntu-18-04-lts-bd4f9ca56620.

After modifying DNS entries in /etc/systemd/resolved.conf I was able to execute NC script with lesser issues regarding resolving external server names.

Modifications in /etc/systemd/resolved.conf:

DNS=8.8.8.8 2001:4860:4860::8888
FallbackDNS=8.8.4.4 2001:4860:4860::8844

To be fair the app server was not always reliable. We improved the config, that should hopefully help.

Definitely I bet on 1 &| 2.

The app server got more stable, haven't seen this for a while. Closing.

FWIW, I have been hitting this issue for the last 15 minutes via php occ app:install and searching for the problem found this threa, but it now appears to have resolved itself so I suspect that the app servers were having issues again?

Same for me here. NC 21.0.1 running inside the official Docker image.
Random.
See https://gist.github.com/mmallejac/cc6bde4f752bfad977a0941571fb0e3a for the nextcloud.log issued while running the occ app:install command
