Server: Internal Server Error

[makemegit]

After updating calendar from the webui i get "Internal Server Error"

The log is saying this:

10.0.10.48 - - [21/Jan/2020:11:37:49 +0200] "GET /index.php/apps/files/ HTTP/1.1" 500 13822 "-" "Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:72.0) Gecko/20100101 Firefox/72.0"

but i cannot find anything wrong. The nextcloud client is working but the webui doesnt anymore.

Any ideas?

*nc 17.0.2.1
*calendar ## 2.0.1 - 2020-01-20

Can't spot anything calendar related, moving to server ...

[newhinton]

I also encountered this bug after updating apps. I know that the calendar app was to be updated, or i was updating it, i am not sure about how exactly the calendar app was involved.

1. I tried restoring a Backup (just the nextcloudfolder, not the datadir or the database)
   -> no result

2. Disabling calendar and multiple other apps (trying to find the one that updated last)
   -> no result

./occ tail:watch resulted in the following errors:

  Error PHP  Invalid argument supplied for foreach() at ***cloud/lib/private/Files/Type/Detection.php#107 2020-01-21T12:07:24+01:00

This may not be related to the issue. I will report back when i progress to a solution

[born2webdesign]

I had an „Internal Server Error“ in the Files App (everything else seemed to work fine) – disabling „Metadata“ solved the issue for us (also one of the Apps that saw an update today).

[phiL0co]

Same happened for me!
Everything worked fine, then I updated metadata and calendar (to 2.0.1) today and now I can't access my nextcloud and get an internal server error, too!

edit: I can still access my nextcloud via the android app as usual!

@born2webdesign thank you very much. You are absolutely right. The package to blame is metadata, not calendar.

Fix:
sudo -u www-data php occ app:disable metadata

For people having the issue with Files :
I had the same issue with the Files app, it is indeed due to Metadata app (as suggested by @born2webdesign)
But the latest 0.11.1 version of Metadata solves the issue... Files now works :)

A new version of metadata has been published and solves the issue on my side ! :)
