Brave (browser) snap on Ubuntu 14.04 won't launch

#1

I was testing a few snaps on 14.04 today and had some quirky behaviour I’d not seen before.

I installed brave on 14.04 under VirtualBox 5.2 with snap install brave --beta. On first launch it fell over with a bizarre chromium error I sadly didn’t capture. I thought I’d update everything (virtualbox extensions, apt updates etc) and try again. When I rebooted, brave was now ‘broken’ such that I got “internal error, please report” that brave snap was not found. Never seen that before and didn’t know where it came from.

Snap info show the snap is indeed broken.

alan@alan-VirtualBox:~$ snap info brave

I refreshed to try and ‘fix’ it. (surely it shouldn’t get in this state?)

Still broken.

So I reinstalled.

alan@alan-VirtualBox:~$ snap remove brave
brave removed
alan@alan-VirtualBox:~$ snap install brave --beta
brave (beta) v0.19.66dev from 'brave' installed
alan@alan-VirtualBox:~$ snap changes

Now it’s installed, but I get a new and interesting error.

alan@alan-VirtualBox:~$ brave
cannot perform operation: mount --rbind /dev /tmp/snap.rootfs_JHMoLN//dev: No such file or directory

Wat.


Node-red snap won't launch on 14.04
#2

Can you please add snap version?


#3
alan@alan-VirtualBox:~$ snap version
snap    2.28.5~14.04
snapd   2.28.5~14.04
series  16
ubuntu  14.04
kernel  4.4.0-98-generic

#4

This is curious. I will look at it.


#5

Same issue on Solus, Arch and never versions of Ubuntu :disappointed: Also please update to 0.19.88 that is the latest version :wink:


#6

FWIW snap debug log from running brave successfully on Arch is right here: https://paste.ubuntu.com/25952347/


#7

I did some more digging and I found that Arch starts on my Thinkpad W510 running Ubuntu 17.10 (natively) and so does when virtualized in gnome-boxes (qemu+qxl) on Fedora 26, Arch and Debian 9 (Debian Sid is not working because apparmor was recently enabled by default there and we need to adjust a few things, see this thread: Snapd 2.27.6-2 in Debian sid blocked on apparmor in kernel 4.13.0-1)

On Ubuntu 14.04 I don’t have much luck though. I’m investigating what (may) be going on there.
On Ubuntu 16.04 it works OK, since it is a a strictly confined snap whatever is causing the issue is interesting, to say the least.

I also saw some reporters say the application failed with invalid opcode, perhaps it was compiled for newer instruction set and those running with a recent-enough CPU just don’t see this?

I’m not sure what the issue is TBH. I cannot work on this now as there are some high-priority issues I need to address first.
