Segfault on launch #1

Closed ronnocnave closed 6 years ago

ronnocnave commented 7 years ago

Hello. Running this snap on KDE Neon (16.04 LTS), I get a segfault on exec. No other information is provided.

james@james-neon:~/Downloads$ minecraft-nsg Segmentation fault

nsg commented 7 years ago

@ronnocnave what type of graphics card are you using? We have a know problem reported here https://github.com/konstructs/client/issues/210. We have been able to reproduce the bug on Intel graphics and I hope to push a fix for that within a day.

@ronnocnave can you check /var/log/syslog if apparmor is blocking anything on your system?

Lines that look like this:

Hello again. Yes, that does appear to be the case. A log search turned up the following lines:

"james-neon kernel: [ 8482.945613] audit: type=1400 audit(1476992251.334:15): apparmor="DENIED" operation="file_mmap" profile="snap.minecraft-nsg.minecraft-nsg" name="/usr/lib/snapd/snap-exec" pid=4532 comm="snap-exec" requested_mask="m" denied_mask="m" fsuid=1000 ouid=0 Oct 20 15:37:58 james-neon /usr/lib/snapd/snapd[4404]: daemon.go:174: DEBUG: uid=1000;@ GET /v2/snaps 685.233µs 200 Oct 20 15:37:58 james-neon kernel: [ 8509.743315] audit: type=1400 audit(1476992278.132:16): apparmor="DENIED" operation="file_mmap" profile="snap.minecraft-nsg.minecraft-nsg" name="/usr/lib/snapd/snap-exec" pid=4556 comm="snap-exec" requested_mask="m" denied_mask="m" fsuid=1000 ouid=0"

So this appears to be a match to what you were suspecting. Hope that helps.

Hi. I am running an AMD R7 260x card with Radeon graphics. Let me know if I can help further.

Have you been able to execute other opengl snap's? I'm considering some problem with your graphic driver and snapd. For example, the snap ubuntu-calculator-app requires opengl, do that work for you?

Closing old issue. If you still have a problem, feel free to open it again.
