Installing site as Progressive Web App does not create launcher icon

[Patrick Herring]

Using Epiphany snap version 3.38.6-2-gc27a8180e1 (latest stable) on Ubuntu 20.04.3 (GNOME 3.36.8).

Navigating to a page and selecting "Install site as Web Application..." does not result in the expected behaviour of creating a launcher icon in GNOME. The web page does show in the list at Epiphany's own Application Manager, and can be removed using the GUI. However there is no way to open the web application or use it as intended.

I have also tested the behaviour using the DEB version of Epiphany, and the bug is not present.

Hi there, this issue has come up for me on all packaged versions of epiphany - except no record of app in application manager either. Gnome has closed the issue as it isn't them. Please see thread: https://gitlab.gnome.org/GNOME/epiphany/-/issues/2357

Gnome believe this to be an Ubuntu issue.

Thanks all.

Status changed to 'Confirmed' because the bug affects multiple users.

Hi. I have the same problem, also with all packaged versions of Epiphany, and using Ubuntu 24.04 (WebKitGTK 2.44.1, GStreamer 1.22.11).

I am posting here the possible issue that was suggested when it was reported in Gnome, in case it helps:

The icon validator is broken when --sandbox flag is used. Apparently, RTM_NEWADDR is required for bubblewrap to create a new network namespace.

It would be failing here:

Thank you.
