[Bug 1512219] Re: apt appears to be confused when installing a backport that version depends on other backports

2016-04-27 Thread Stéphane Graber
"apt-get -t trusty-backports install lxd" would have been significantly
easier and less error prone.

But yes, the apt bug itself hasn't been fixed as can be seen by this bug
still being open.

I don't think apt resolving is fixed yet in trusty apt=1.0.1ubuntu2.13
(27.4.2016)

To get lxd installed, this is what I used:
apt-get install lxd/trusty-backports lxc/trusty-backports 
liblxc1/trusty-backports python3-lxc/trusty-backports

Thanks for your bugreport.

I looked into this issue and it seems like its indeed a bug in apt that
it will not properly do a version check when switching the candidate
version to trusty-backports.

Attached is a patch that adds some debug code and also a potential fix
for the problem, it breaks one of the existing tests, I need to inspect
if the test is incorrect though. So its probably not the final diff but
it highlights the prolem area.

For it to fully work you need to adjust the python3-lxc dependency in lxc too, 
please add something like:
  Depends: python3, python3-lxc (>= 1.1.4-0ubuntu1.1~ubuntu14.04.1)
(i.e. ensure that apt knows it needs to pick a reasonable high version). This 
is useful regardless of the diff.

** Patch added: "apt diff"

Hi Michael, I have uploaded an updated lxc to the trusty-backports
queue. Will ping someone on the backports team to get it in, thanks.
