Bug Description

[This was also sent to <email address hidden>.]

Hi,

I followed the steps in the "Launch Snappy locally with KVM on Linux"
section on http://www.ubuntu.com/cloud/tools/snappy. Then I ran the
steps in the "A snappy tour of Ubuntu Core!" section on
http://www.ubuntu.com/cloud/tools/snappy. Sorry, I don't see a way to
link directly to these sections. I ran into a few problems. Please see
below.

kvm is running just fine, no errors.

This is on a 64-bit version of 14.10. I am running with LUKS encrypted
root partition and an ecryptfs encrypted home directory, if that's
relevant.

Thanks.

-Tom

I had a few folks try to reproduce by installing, uninstalling docker to no success. Could you try reproducing from a clean image download and give us step by step instructions?

tried myself:

1. start with fresh image
2. snappy install docker
3. snappy uninstall docker
4. snappy install docker
5. snappy install owncloud
6. snappy uninstall docker
7. snappy install docker

-> all success

guess:

InterruptedError: [Errno 4] Interrupted system call

is what caused you get in such state... would be great to get repro instructions and the log that barry asked for in comment #2

I suspect the problem is SIGWINCH. I can reproduce this problem if I resize or maximize the terminal window while snappy installs docker. However once things fail they seem to continue to fail no matter what.
