FTBFS since lxc has different version numbers in Debian and Ubuntu

[Hans Joachim Desserud]

The lua-lxc [1] package currently fails to build since it cannot satisfy the build dependency: lxc-dev (>= 1:3.0.2-1~exp+1).

Looks like this is caused by different version numbers in Debian and Ubuntu. The latest version in Debian unstable is 1:3.1.0+really3.0.3-8 while Ubuntu eoan has 3.0.3-0ubuntu1. I believe the 1: epoch (?) is causing this issue.

Presumably lua-lxc needs to be patched to allow the Ubuntu package to fulfill the build requirements.

I'm uploading lua-lxc with an adjustment to the versioned build-dependency, since this has been stuck in -proposed for 250 days already. But ultimately it would be better if Ubuntu followed Debian on the epoch of lxc-dev. I see no reason not to.

[Gianfranco Costamagna (costamagnagianfranco)]

@vorlon, I did followup on your upload, by also dropping epoch on the runtime liblxc1 dependency, to avoid it being stuck again in queue...
it should finally migrate now.

I asked a while ago to Ubuntu lxc developers to bump epoch, and they were happy with that... not sure why they forgot, but I'm going to open a bug now.

So I think I'll be doing the epoch bump with 4.0 which should help somewhat.
There will still be the issue of not having the binary packages themselves lined up (different names) but that should be a step forward.

This bug was fixed in the package lxc - 1:4.0.0-0ubuntu2

The epoch was added to lxc.
lxc-lua seems to have built successfully.
And since then the delta was dropped when a new version of lxc-lua was synced from Debian (https://bugs.launchpad.net/ubuntu/+source/lua-lxc/1:3.0.2-2)
