Imagick security issue, theming can't be disabled


Theming app requires imagick package, however it has a vulnerability that can be fixed only with ubuntu pro esm :frowning_face:

I’ve uninstalled the vulnerable packages but now my pretty green all ok changed to orange with the warning:

  • The PHP module “imagick” is not enabled although the theming app is. For favicon generation to work correctly, you need to install and enable this module.

I’ve tried to disable the theming app, but

theming can't be disabled.

Is there a way to fix this with free ubuntu 22.04 LTS?
My nextcloud is 27.

It has tons of vulnerabilities… :wink: but not all of them are critical, and not all of them do affect all Ubuntu releases, according to your link.

Not an official way, and I wouldn’t recommend to manually replace the package, or load it from some random PPA (if any exist), except you know exactley what you’re doing. However you can register five computers for free… Ubuntu Pro | Ubuntu

Free for personal use

Anyone can use Ubuntu Pro for free on up to 5 machines, or 50 if you are an official Ubuntu Community member.

Free for personal use

That’s the issue, it’s not personal use.

Well, then you probably have to pay if you want that Extended Security Maintainance. Or you could use a free (as in freedom) distro like Debian which backports a lot of security fixes, and most if not all of the critical ones. Or maybe you could use a derivative of an enterprise distro that you don’t have to pay for (openSUSE leap comes to mind).

Your problem has nothing to do with imagemagick or with Ubuntu 22.04!

I also don’t know why you can’t install or update imagemagick. For me, it is present in the regular package sources of Ubuntu 22.04 (even if the Ubuntu web page says otherwise):

# apt list imagemagick*

My understanding is that the theming app is no longer needed, as its features are now hardwired into Nextcloud. However, it was forgotten to remove the corresponding app in existing installations. Thus, the app remains orphaned in existing installations and can no longer be uninstalled in the App Store. Also, the attempt to remove this app on the command line fails with the note that this app is now a fixed component.

This leaves the app Theming as an abandoned relic of times gone by in Nextcloud and we can only wait patiently until someone from the developers notices and then removes it.

There is no app called Theming listed.

apps/theming is not an abandoned relic. The actual implementation is still there. It’s just not possible to disable the app anymore.
