On my Ubuntu 20.04 install, the theme I was using was working fine with my gtk2 application (which follows our docs) but then I switched to the Yaru theme and the gtk2 app has the old default styling. Wondering if this was local to my snap, I then tried gtk2-demo and found it was also affected by this issue. This is easily replicated with:
$ sudo snap install gtk2-demo
$ gtk2-demo
Change the ‘Applications’ theme via gnome-tweak to Adwaita or Ambiance (for example) and gtk2-demo (and my application) is correctly themed. Change it to Yaru and it is not.
$ snap list gtk2-demo gtk-common-themes gtk2-common-themes

I think you this fixes it:
environment:
GTK_PATH: $SNAP/lib/gtk-2.0
Either that or this does:
environment:
GTK_DATA_PREFIX: $SNAP
I have both of those set in audacity and I believe it is styled correctly…
In my snap, I have both of these:
environment:
...
GTK_DATA_PREFIX: $SNAP
GTK_PATH: $SNAP/lib/gtk-2.0
...
So does gtk2-demo:
environment:
GTK_DATA_PREFIX: $SNAP
GTK_PATH: $SNAP/lib/gtk-2.0
...
audacity is not styled correctly for me in an up-to-date focal install using yaru

The leafpad snap is properly themed, which is what I use as my test case.
For reference: https://github.com/kenvandine/leafpad-snap/blob/master/snapcraft.yaml
gtk2-demo is also working for me. I have gtk-common-themes and gtk2-common-themes from the candidate channel
OK, gtk-common-themes from edge is broken. Use either candidate or stable. I think the edge build comes from Yaru’s CI. I’ll check in with them to see what’s going on with that.

try again
(I had only released it to beta. it’s now in stable)
I confirmed that using either stable or candidate works great. Thanks!

@clobrano I think Yaru is publishing gtk-common-themes to edge from CI. The version being published in CI is missing quite a few fixes including the gtk2 variant of Yaru that’s built as part of the snap build.
This might be due to an error I made in a test PR. Is there any other way to trigger a new gtk-common-theme build?
I could just publish our latest build to edge to replace what’s there?
Do you not have an automated build that publishes?

There’s a CI, but only when pushing to bionic branch
Excellent - thanks @lucyllewy
I could try now to push some update to bionic, and see if this trigger the correct rebuild of edge for both
EDIT: or, I could be a little smarter and trigger again the CI on bionic branch ![:roll_eyes: :roll_eyes:](https://forum.snapcraft.io/images/emoji/twitter/roll_eyes.png?v=12)
I rebuilt gtk-common-themes
with the content from the proper branch.
