Cannot install click packages on the unity 8 desktop session

Hey David,

I have no experience trying to install clicks. neither on a regular host nor a unity8-lxc.

Are you able to install a click on your host via command line, ie, not in the LXC?

Also, I'm not sure what you mean by:
"When trying to install from the unity8 session: I get a "Failed to obtain authentication" error."
Are you trying to install a package via the Store? If so, this is not supported.

Thanks!

Sorry, I wasn't clear: when I said "on the host", I meant actually
installing it in the container, but from the host's unity7 session via
lxc-console. When I said "on the unity8 session", I meant having logged
into the unity8 session, having started the terminal app and ran the 'pkcon
install-local' command from there.

I guess you mean from the host's unity 7 session. I had never tried it,
assuming you needed a unity8-based system to do it. But I gave it a go and
here's the result:

No, I didn't use the store, I used the terminal ^, as I was aware of bug
#1466009

Thanks for the help!

Had a chat about it on #ubuntu-app-devel:

<sergiusens> dpm: ogra_ nik90 i'm just guessing, but you may not have a click database initialized
<sergiusens> dpm: pkcon install won't work unless you have the right security polkit bits setup
<popey> sergiusens: That's what we're missing - and no idea how to set that up
<sergiusens> popey: dpm https://click.readthedocs.org/en/latest/databases.html
<sergiusens> popey: dpm you would need to setup the polkit rules, check the phone, under /etc/polkit something
 popey: dpm and I think the right bits for polkit are in lxc-android-config
<dpm> sergiusens, does this look like what would be needed to have installed? http://pastebin.ubuntu.com/11736592/
 doesn't seem to list any polkit rules, though
 the polkit-1 package seems to have http://pastebin.ubuntu.com/11736591/

In summary, from what I could gather it seems that to be able to install click packages from the command line:

1) A click database needs to be registered
2) A set of polkit rules need to be installed

Hi David,

After reading your last few comments, I'm not sure who is supposed to install the needed bits in order to make this work. I'm pretty sure it's not unity8-lxc though:)

Thanks for digging deeper into this.

Also, once installation of click packages works on the non LXC desktop, then we'll see if it works in unity8-lxc. If not, then that would be in my court.

Status changed to 'Confirmed' because the bug affects multiple users.

I am able to install click packages with pkcon from Ubuntu 15.04 but have the same issue as stated here.

I got it to work. Basically only running apparmor under lxc is a problem now and everything else is working.

I got it to work by adding the following to /var/lib/lxc/unity8-lxc/config:

    lxc.aa_profile = unconfined
    lxc.cgroup.devices.allow = a
    lxc.cap.drop =

This makes the lxc container insecure, but usable.

Also see bug 1396611 for the (non-LXC) unity8 session counterpart.
