[Bug]: snap GUI applications not working on Ubuntu WSL2 win 11 #27

Open tomasz-gac opened 2 years ago

tomasz-gac commented 2 years ago

Describe the bug

I cannot run GUI apps installed via snap. Installing and running snap-store yields:

update.go:85: cannot change mount namespace according to change mount (/var/lib/snapd/hostfs/tmp/.X11-unix /tmp/.X11-unix none bind,ro 0 0): cannot use "/var/lib/snapd/hostfs/tmp/.X11-unix" as bind-mount source: not a directory
mkdir: cannot create directory ‘/run/user/1000’: Permission denied
Unable to init server: Could not connect: Connection refused
22:17:06:0160 Gtk cannot open display: :0

The same final Gtk error exists for Chromium

Steps to reproduce

  1. Install Ubuntu from Microsoft app store on Windows 11
  2. Install distrod, option 2 on already installed distro
  3. sudo snap install snap-store
  4. snap-store

Expected behavior

Snap store GUI opens

Windows version

11

Linux kernel version

Linux DESKTOP-HUAWEI 5.10.60.1-microsoft-standard-WSL2 #1 SMP Wed Aug 25 23:20:18 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux

Distro

Ubuntu 20.04

How did you install that distro?

Enabled distrod in an existing WSL2 distro

I made a symbolic link from $XDG_RUNTIME_DIR to /run/user/1000 and it works

tomasz-gac commented 2 years ago

@dingdang66686 just attempted this, now the error is: update.go:85: cannot change mount namespace according to change mount (/var/lib/snapd/hostfs/tmp/.X11-unix /tmp/.X11-unix none bind,ro 0 0): cannot use "/var/lib/snapd/hostfs/tmp/.X11-unix" as bind-mount source: not a directory error: access denied ERROR: not connected to the gnome-3-28-1804 content interface.

Wayland application works in this way.

For x11 apps, you should delete /tmp/.X11-unix and make a bind mount to wslg's .X11 dir.
