Re: Cliqz Snap

Hi Chris,

You may find the tips at https://github.com/snapcore/snapd/wiki/Security.
You may use the command like:

$ scmp_sys_resolver 983045
set_tls

to find out the security violation.

Best regards,
XiaoGuo

Cliqz Snap

[Chris]

Has anyone gotten this snap to run? The install went fine AFAICT but
when executed nothing happens. Syslog shows

Nov 12 17:00:55 localhost /usr/lib/snapd/snapd[844]: daemon.go:174:

Re: configure hook

[Boris Rybalkin]

Still struggling with hooks, they are not executed on install.

snap$ snap run --hook=configure syncloud-platform
cannot snap-exec: cannot find hook "configure" in "syncloud-platform"
and even 'snap run --hook=configure mysnap' silently returns.

I am using:
Ubuntu 16.04
snapd 2.16ubuntu3

Does it have hook support?

According to this test they should even fail install if broken:
https://github.com/snapcore/snapd/blob/203591b28670ef5c4106c8fc43051500bd6c3fda/tests/main/snap-set/task.yaml

As suggested I am copying meta/hooks to prime dir after running snapcraft
prime  and then running snapcraft snap.

This bug says it is probably not yet available in edge, how do I switch
channel?

Thank you.
