Bug Description

Yakkety, libertine trunk, python3-lxc 2.0.4.

To reproduce:

* Create a container
* Enable multiarch
* In the GUI, install "steam"
* Navigate to the PackageInfoView
* In the informational section, you are prompted to agree to TOS
* Type "1" to disagree or "2" to agree and hit Return

Nothing happens. The QProcess believes that it has sent the bytes to the process, but it seems that the container never gets it.

I'm fairly certain this is directly related to a bug I've filed with lxc where attach_wait permanently steals stdin from the python process (https://github.com/lxc/lxc/issues/1137).

After digging through the python-lxc code a bit, it's unclear to me why this might be happening. Also considering that the bug I filed has been completely ignored, I think we'll need to find a workaround instead of relying on a real fix upstream.

I'm going to investigate possibly pushing the attach_wait command into its own process, and then redirecting stdin/stdout as possible.

Lots more research later, I've found that this is only happening on yakkety. I created a xenial container and tried to install steam, and was able to complete the install just fine. I've also noted that there are some strange characters that show up in the yakkety install details. I do not know if this has to do with versions of apt, versions of the steam deb, or something else entirely. This could be caused by the fact that yakkety is not currently supported by steam.

Mystery solved - the issue actually stems from using the "readline" frontend in general. If we instead fallback to the "teletype" frontend, everything works fine.

¯\_(ツ)_/¯

Will push a fix and cli update shortly.
