Error: Exception: App with id guests has invalid signature

[nunesgh]

Hi,

I'm currently unable to update the guests app from version 1.6.1 to 1.6.2. According to my Nextcloud instance, the new version has an invalid signature. The same issue is currently happening with the files_antivirus app.

Thank you!

As pointed out here in the Nextcloud Help community, this issue is somehow related to presence of the External Storage: OneDrive app. Removing it solves the app update problem.
