Cannot run flatpaks anymore

English Applications

Yesterday I’ve been using EasySSH extensively. Today I cannot start it:

~> LANG=C flatpak run com.github.muriloventuroso.easyssh
Gtk-Message: 11:49:12.132: Failed to load module "unity-gtk-module"
Invalid MIT-MAGIC-COOKIE-1 keyUnable to init server: Could not connect: Connection refused

(com.github.muriloventuroso.easyssh:2): Gtk-WARNING **: 11:49:12.145: cannot open display: :99.0

All my other flatpaks refuse to start, too:

~> flatpak run io.gitlab.Goodvibes
Gtk-Message: 11:54:32.369: Failed to load module "unity-gtk-module"
Gtk-Message: 11:54:32.369: Failed to load module "canberra-gtk-module"

This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

Available platform plugins are: eglfs, minimal, minimalegl, offscreen, vnc, wayland-egl, wayland, wayland-xcomposite-egl, wayland-xcomposite-glx, xcb.

I updated everything with “flatpak update” but still I cannot run any flatpak.
Any hints?

Thank you in advance

Maybe you should consider a bug report.

Submitting Bug Reports

(that link seems to be misbehaving, but it usually works).

Very similar errors shown in this Dec 2018 bug report…

Flatpak deosn't start app anymore. How to troubleshoot?

If you are having invalid MIT-MAGIC-COOKIE-1 issues then:

(a) logout.
(b) Use CTRL-ALT-F1 to get to a command line, and login there (as yourself).
(c) rm .Xauthority
(d) Use CTRL-ALT-F7 to get back to the GUI login screen.

And then login again, and see if that helped.
