I came to know that I have an AlaDelta theme sitting/hiding somewhere on the system. I tried the following approaches -

$ apt-file search aladelta

with variations of aladelta in some caps, all caps but no avail.

$ aptitude search aladelta 

Also tried various theme packages which I have installed to see if one of them might have this theme but it's a long slog.

[$] dpkg -l | grep -i theme

Any ideas how to figure out where this theme might be holed up ?


is empty.

[~/.config/gtk-3.0] - [10106]
└─[$] cat settings.ini                                                                                                                
gtk-font-name=Sans 12

This has become an issue as the theme is supposed to be a fork of adwaita and is obsolete by many years. I came to know about it as it started giving gtk warnings as just have upgraded to gtk-3.20 .

  • You should post the content of the gtk warnings. I'm guessing you'll find a path in there and then you can use dpkg -S <somefile> to tell you the package that owns the file. – Peter Jun 1 '16 at 12:22
  • Actually while I can share the content of gtk warnings, I don't think that will help in this case .

    Looks like it's a Mate theme according to git.mate-desktop.org/mate-themes/diff/…. You really need to clean up /usr/share/themes :) GTK-3.20 is well known for breaking older themes! Even the Arch guys are complaining. Unless you find a theme that's expressly written for GTK-3.20, you're going to face issues. If locate or mlocate doesn't find it, why do you think it's still around? – DK Bose Jun 1 '16 at 15:26

The AlaDelta theme does not appear to be in any standard Debian package.

If you installed it from a non-standard package, you could find out the package name with:

grep -il aladelta /var/lib/dpkg/info/*.list

Alternatively, if that results in an error message about "argument list too long" or similar:

find /var/lib/dpkg/info -name '*.list' -exec grep -il aladelta {} +

The package name will be the filename without the .list suffix.

If that doesn't find it, it's a local (i.e. non-package) install, perhaps somewhere under /usr/local/. If you have mlocate installed, you can find out where the theme is on disk by running mlocate -i aladelta. You should then be able to delete the theme's files.
