Flatpak edition segfaults on loading sandbox

[JLIT0]

Also segfaults when the --nosandbox flag is added to the command.

However, the .deb for release 0.3 works fine.

Any chance of releasing a .deb as well?

@JLIT0 Hmm ... @plfiorini might know details about the flatpak issue. Try if exporting QTWEBENGINE_DISABLE_SANDBOX=1 does the trick.

Any chance of releasing a .deb as well?

What if you try out our new snap packages as replacement for a deb? It's as easy as snap install --edge liri-browser :)

Never experienced this problem, I will try again but it could be hardware related. There is a QtWebEngine bug with nouveau that is fixed in the upcoming Qt 5.10.0.

@JLIT0 are you using nouveau?

If it's the nouveau bug, try exporting QT_XCB_FORCE_SOFTWARE_OPENGL=1 to force software rendering.

Hi there! Many apologies, I didn't see this before. Yes, I'm using the Noveau drivers so I guess that's the reason for the segfault. I'll try the NVIDIA Xorg drivers and see what happens with them.

As for the snap, it lead to a different set of issues as quoted below:

X@X-laptop:~/Downloads$ sudo snap install --edge liri-browser
liri-browser (edge) 0+git.e4f36a2 from 'liri' installed
X@X-laptop:~/Downloads$ liri-browser
You need to connect this snap to the Liri Platform snap.
You can do this with those commands:
snap install liri-platform-0-9
snap connect liri-browser:platform liri-platform-0-9:platform
X@X-laptop:~/Downloads$ sudo snap install liri-platform-0-9
snap install liri-platform-0-9
error: snap "liri-platform-0-9" not found
X@X-laptop:~/Downloads$ sudo snap install liri-platform-0-9
error: snap "liri-platform-0-9" not found
X@X-laptop:~/Downloads$ sudo snap connect liri-browser:platform liri-platform-0-9:platform
error: snap "liri-platform-0-9" has no slot named "platform"

Hey @JLIT0, yeah, it should work with the proprietary drivers or when forcing software rendering.
Regarding the snap issues: Sorry, I should've mentioned it, you need to install the platform snap from the edge channel as well:

sudo snap install --edge liri-browser
sudo snap install --edge liri-platform-0-9
sudo snap connect liri-browser:platform liri-platform-0-9:platform
snap run liri-browser

Hi there,

Thanks for the advice! I was able to get the browser running by using the snap as described and by switching to the NVIDIA drivers.

I can reproduce the segfault with the Flatpak package on Ubuntu 17.10 (Intel integrated graphics):
