Problems running snapcraft, uname crashing?

willfaris · March 22, 2018, 4:56pm

snap/bin/snapcraft --version
snapcraft, version 2.39.2

snap list
Name       Version    Rev   Developer  Notes
core       16-2.31.2  4206  canonical  core
snapcraft  2.39.2     1177  canonical  classic

when running snapcraft I get this error and it looks like uname -srvmpio is the problem?, when I run uname manually on the host machine with those flags it works OK.

Do you mind trying snapcraft from edge?

Using

/snap/bin/snapcraft --version
snapcraft, version 2.39.2+git53.e7b9d74
snap list
Name       Version               Rev   Developer  Notes
core       16-2.31.2             4206  canonical  core
snapcraft  2.39.2+git53.e7b9d74  1322  canonical  classic

uname -srvmpio from the host OS shows

Linux 4.4.0-83-generic #106~14.04.1-Ubuntu SMP Mon Jun 26 18:10:19 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux

I am getting the same error, truncated stack trace below, maybe this is not a problem with snapcraft but something wrong with the underlying machine, is the uname command run under some special context when snapcraft runs it that maybe I can mimic and see what might be going on?

Is this classic and non xenial? I thought I added the warning already about building with this combination. I will check again.

The snap being built is classic, and snapcraft is not running on xenial.

willfaris · March 29, 2018, 2:16pm

Is there any supported path to build a classic snap using snapcraft on trusty? I was able to build the snap using docker https://github.com/snapcore/snapcraft/tree/master/docker on trusty but while the created snap installs locally there are problems publishing it to the store.
