I installed a OneDrive addon, and now it broke my nextcloud instance.
I am using nextcloud v20.0.4
when I access my server I get 500 responses in browser.
On server side I see these logs:
192.168.64.2 - - [29/Dec/2020:03:39:53 +0000] "GET / HTTP/1.1" 500 425 "-" "Mozilla/5.0 (Macintosh; Intel Mac OS X 11_1_0) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/87.0.4280.88 Safari/537.36"

192.168.64.2 - - [29/Dec/2020:04:19:05 +0000] "GET / HTTP/1.1" 500 425 "-" "-"
Then I thought, since I can’t use the UI to disable the addon, maybe I can do it via command line. problem is
I don’t know the name of the addon. in order to call php occ app:disable NAME_OF_APP
So to find out tried to run this to list all the adodn names: php occ app:list
but that command gives this error:
An unhandled exception has been thrown:

So i’m stuck.
It is a bit worrying that something as simple as installing an addon can brick the server. I imagine addons should be sandboxed in some way. Or at least have a way to back out of it if it breaks stuff.
Sounds like the app is defect, you could try downloading it from github, putting the files on the webserver and setting correct permissions, probably that helps
Yea trouble is I don’t even know for sure which github it is. Because I can’t get into Nextcloud in order to look up the addon that I so glibly clicked “install” on. So I don’t remember the exact title of it, let alone the github repo it comes from. I just know it was something for enabling OneDrive external storage.
At this point I just want to remove the addon, I don’t care to make it work. Just want my Nextcloud instance back…
I didn’t do anything special. The addon was marked compatible with the version of Nextcloud i’m using, so I didn’t do anything crazy like force-enable an incompatible addon or anything.
I guess i’m confused how this might work to fix it. I thought installing the app through the Nextcloud GUI as I did the first time does basically this. Which ended up breaking the server in the first place…
Thanks… I actually ended up renaming the files_external_onedrive folder that was already there to files_external_onedrive_bak, and that actually allowed me to get back in to the GUI. From there I was able to disable the onedrive addon, then I went back in the filesystem and renamed the files_external_onedrive_bak back to the original name files_external_onedrive. This allowed me to now properly delete it from the GUI.
