2016-04-21 Thread Philipp

Did a fresh install, could it possibly be that the unity8-lxc package vanished 
from xenial?
Because I don't know how to create the lxc container by hand.

2016-04-20 Thread Philipp

Yes.

The ppa updated following packages:

lxc1 amd64 2.0.0+master~20160415-1123-0ubuntu1~xenial
python3-lxc amd64 2.0.0+master~20160415-1123-0ubuntu1~xenial
liblxc1 amd64 2.0.0+master~20160415-1123-0ubuntu1~xenial
lxc-common amd64 2.0.0+master~20160415-1123-0ubuntu1~xenial
lxc-templates amd64 2.0.0+master~20160415-1123-0ubuntu1~xenial

Still I cannot start the session nor update it.

I will upgrade my laptop to Xenial as well soon and try it again with a
fresh install on other hardware.

No that should actually be ok, it's ../Zulu not ./Zulu.

Could you show the contents of

/var/lib/lxc/unity-lxc/config
/var/lib/lxc/unity-lxc/fstab

(I'll also be asking for contents of any files listed in lxc.include
lines)

[Touch-packages] [Bug 1567037] Re: lxc-attach crashed with SIGSEGV in get_pty_on_host()

2016-04-11 Thread Serge Hallyn

To be precise, the container name should be unity8-lxc.  Please also
show it's configuration file, and try

lxc-ls -f
lxc-start -n unity-lxc
and if that fails, then
lxc-start -n unity-lxc -F -l trace -o output

and attach the file 'output'

[Touch-packages] [Bug 1567037] Re: lxc-attach crashed with SIGSEGV in get_pty_on_host()

2016-04-10 Thread Philipp

I did a fresh install of the latest daily build and still I am unable to log 
into the lxc session in from unity-greeter (same behaviour as before).
But now there is no more popup if I want to report a bug.


If I try 'sudo unity8-lxc-session' this happens:

lxc-attach: attach.c: lxc_attach: 730 failed to get the init pid
/usr/bin/unity8-lxc-session: 30: /usr/bin/unity8-lxc-session: cannot create 
/proc//root/etc/passwd: Directory nonexistent

2016-04-06 Thread Serge Hallyn

Thanks for reporting this bug.  I haven't reproduced it, but marked it
confirmed bc I see how it could happen.

A simple fix would be to not dereference ts without checking for it to
be NULL.  The question is whether we should be doing more at
console_create to not honor lxc.console during attach.
