I can confirm this issue. As workaround is disabling onedrive app, update other apps and after enable onedrive app.

I have also experienced this issue (nextcloud/files_antivirus#182 and nextcloud/guests#522) and I can confirm @thekarinka's workaround solves this.

Does anyone know why this is happening?

Hi guys,

@zetix in your logs the app id integration_onedrive belongs to another app. This -> https://apps.nextcloud.com/apps/integration_onedrive. It's not files_external_onedrive. During the tests I did not encounter the same problem. I suppose the workaround proposed by @thekarinka solves.

And remember integration_onedrive is not files_external_onedrive.

[KnudH]

integration_onedrive does not encounter the bug, it is the files_external_onedrive app. I never installed the integration but having the same issue with the files_external_onedrive app.

So pls reopen, as long as the bug is not solved.

@hevelius As I mention in the post, I'm only using the OneDrive integration as an example as the error produced is the same for any other app you're trying to install with files_external_onedrive app enabled.

It's not really a huge issue as it's not like admins on nextcloud are installing and removing apps daily and if needed, disabling files_external_onedrive would resolve the issue.

The problem is that some users aren't aware that files_external_onedrive is the culprit and would go down a rabbit hole trying to solve it. If they aren't able to find a fix, the only other solution would be to do a complete reinstall. It would be great if you add the possibility of this issue occurring as a note to the app description if you are unable to encounter the same problem.

Interesting discussion. Before reopen this issue please tell me

• O.S.
• Configuration: e.g. apache/nginx php version
• NC version
• which other apps you have enabled

so I can do more tests replicating your same issue.

The problem is that some users aren't aware that files_external_onedrive is the culprit and would go down a rabbit hole trying to solve it. If they aren't able to find a fix, the only other solution would be to do a complete reinstall.

Exactly! If I did not find this issue here (thank you @zetix, by the way), the next step would be exactly to do a complete reinstall.

As I have mentioned above, I had signature errors with two other apps and even bothered to open issues on their respective repos (nextcloud/files_antivirus#182 and nextcloud/guests#522).

But what really solved those errors was to remove files_external_onedrive --not integration_onedrive, which wasn't even installed.

Here is my server configuration as well:

• Operating system: Debian 10
• Web server: Apache 2
• Database: MySQL 19.0.3.1
• PHP version: 7.3
• Nextcloud version: 20.0.4
• Where did you install Nextcloud from: Website tarball.

And here are the errors caused by the presence of files_external_onedrive:

• files_antivirus
