Hi, I just tried that with development version of Zentyal and it works for me. Well, there are some caveats, see below. On Fri, 4 Aug 2017 09:31:22 -0400 Wesley Stewart <wstewart3@gmail.com> wrote:

Could you be more specific? What was the problem? Was it problem with python-apt per-se or with ovirt-guest-agent using python-apt?

Hi all,

I have this problem: I'm tring to install the guest tools following this guide: https://www.ovirt.org/documentation/how-to/guest- agent/install-the-guest-agent-in-ubuntu/#for-ubuntu-1604

I've noticed that the ovirt-guest-agent package available in the repository mentioned on the oVirt site is missing dependency on qemu-guest-agent. You have to install it additionally for oVirt to work properly. If you, however, instal the ovirt-guest-agent from official Ubuntu repository there is different issue. There is this unresolved bug: https://bugs.launchpad.net/ubuntu/+source/ovirt-guest-agent/+bug/1609130 You have to fix permissions on /var/log/ovirt-guest-agent as mentioned in the bug report.

But when I try to install, I have this error:

root@vmdczen01:~# apt-get install ovirt-guest-agent Reading package lists... Done Building dependency tree Reading state information... Done Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming. The following information may help to resolve the situation:

I've found that python-apt is in "main" repo:

https://packages.ubuntu.com/xenial/amd64/python-apt/download

So, what's the problem?

Did you run 'apt-get update' to synchronize the repository content? Tomas

Can you help me? Thank you

In the past with Zentyal 5 Dev Edition I had the same error: Added suggested repository that want install "python-apt" and remove "apt-get" (because conflicts)

You have to fix permissions on /var/log/ovirt-guest-agent as mentioned in the bug report.

The problem is the same, if you remove the extra repisotory and then try to use the "main" repository, you have the problem with python-apt

Extra tests:

I have tried to install "python-apt" directly and I can reproduce the problem mentioned by Stewart:

Now, try to install "python-apt":

This is the problem! I looked at the packages for conflict and figured the issue is in gnpug. Zentyal repository contains gnupg version 2.1.15-1ubuntu6 which breaks python-apt <= 1.1.0~beta4.

.

And this is a BIG problem ... Can I open a bug ? Where?

Agreed. Open a bug with Zentyal. They broke the packages from Ubuntu and should fix it themselves. They have to backport newer version of python-apt. The one from yakkety (1.1.0~beta5) should be good enough to fix the problem. In the bug report note that the ovirt-guest-agent from Ubuntu repository cannot be installed. It is not only related to the package from the private repo. Tomas

Did you run 'apt-get update' to synchronize the repository content?

Yes (see above)

Ok, Thank you!

Done: https://tracker.zentyal.org/issues/5279 Thank you Again

Better workaround is to download newer python-apt from here [1] and install it manually with dpkg. The guest agent seems to work OK with it. There's much less chance of breaking something else, also newer python-apt will be picked-up automatically on upgrades.
