Podman: snactor discovery and run issues

[bocekm]

CCing @vinzenz.

[Honza0297]

I am experiencing the same issue.
Not only with snactor discovery, but also with snactor run actors/(does not matter)/actor.py

System info

• fedora silverblue 30 + toolbox with f30 image
• snactor version 0.8.1
• leapp-repository commit https://github.com/oamg/leapp-repository/commit/e355543ae334c1ee886692f019983d7245e9325d

[bocekm]

I've just tried snactor discover after installing the latest snactor build from Fedora Copr (0.8.1-1.201908200828Z.8bbf9d3.master.el7) on my F30. It worked fine. Where did you get the 0.8.1 version from? Paste your traceback here please.

[bocekm]

By the way, the traceback shows that python 2.7 version of leapp has been installed. I have it installed for python 3.7.
@landgraf, @Honza0297, could you please try installing current version of snactor from the Fedora Copr and see if it's installed for python 3? It definitely shouldn't be installed for python 2 on Fedora. Thanks.

[Honza0297]

@bocekm When i was installing leapp according to the tutorial (link), there was a problem with leapp-repository dependency, which is needed in version 0.8.1, but the only available version from Copr repository is 0.3.1, so I had to install it in some twisted way (which I do not remember, unfortunately) - this could be the main reason why it is not working for me.

[bocekm]

@Honza0297, unfortunately we are unable to build leapp-repository in the Fedora Copr at the moment. You can build the rpm locally with the following script: https://0bin.net/paste/J30FLCXiLit10Xgq#OjBkwlGdScLjKgMUxDZkKQXkbRVvS6jsQLSS9wbx4QU
Or ping me or anybody on #leapp IRC and we'll send you a link to the internal Copr with the latest leapp-repository packages.
We're working on a better solution.

[Honza0297]

@bocekm Unfortunately, the script does not work either - rpmbuild fails on %build section.

I have also tried to install snactor again in new f30 container to check if it requires Python 2 or 3 by typing:
sudo dnf config-manager --add-repo https://copr.fedorainfracloud.org/coprs/g/leapp/leapp-devel/repo/epel-7/group_leapp-leapp-devel-epel-7.repo sudo dnf install snactor
and Python 2 is required.

[bocekm]

@Honza0297, you're right, I'm also getting this on f30:

Installing:
 snactor                             noarch                       0.8.1-1.201909041507Z.d251200.master.el7                        copr:copr.fedorainfracloud.org:group_leapp:leapp-devel                       8.7 k
Installing dependencies:
 python2-leapp                       noarch                       0.8.1-1.201909041507Z.d251200.master.el7                        copr:copr.fedorainfracloud.org:group_leapp:leapp-devel                       176 k

It should be requiring python3-leapp.

[bocekm]

Actually it should be requiring python2-leapp because that's snactor for CentOS/RHEL7. I was blindly copy pasting your command and didn't catch that the repo you used is not for F30. Use this instead and python3-leapp will be installed:
sudo dnf config-manager --add-repo https://copr.fedorainfracloud.org/coprs/g/leapp/leapp-devel/repo/fedora-30/group_leapp-leapp-devel-fedora-30.repo

[Honza0297]

@bocekm Great, thanks!
By the way, it would be useful to update the tutorial to reflect these differences. As a newcomer to leapp, I just did what the tutorial told me without knowing there is also f30 repo.

[bocekm]

@Honza0297, good point, thanks.

[Honza0297]

@bocekm After I used the f30 repo and installed snactor from it, there is no change and snactor still throws the same error as before.

[bocekm]

@Honza0297, please paste the error here.

[Honza0297]

@bocekm Would be possible to make a direct conversation (on IRC for example) if you have time?

[bocekm]

@Honza0297, sure, mbocek nick on #leapp. Or stop by at 2D383 in TPB-C.

[bocekm]

The issue may be podman related - @Honza0297 runs a F30 pod.
There seems to be also an issue, maybe related, with socket.getfqdn() as it takes around 10 seconds.

With 0.8.1-100.201909061315Z.723e780.master.el7 snactor installed:

$ snactor

[vinzenz]

Actually I wonder where snactor repo scan was run from.
Also it would be a good idea to run snactor repo healthcheck

[Honza0297]

snactor repo health-check has no output here. And after run it, snactor discover still fails.

Path where we run snactor commands is:

$ pwd 
/home/jaberan/Documents/projects/rhel_upgrade_script/leapp-repository/repos/system_upgrade/el7toel8

[vinzenz]

You need to run

$ snactor repo find --path /home/jaberan/Documents/projects/rhel_upgrade_script/leapp-repository/repos

The common repo is not registered which is in leapp-repository/repos/common

That should solve that problem with the discovery for you.

[Honza0297]

Good news: error with missing repo is fixed! Thanks!
However, another problem occurred. When I run snactor run --debug (actor) where (actor) is any actor, I get no output. It should write at least some logs like here in tutorial (bottom of the page), shouldn't it?

[bocekm]

Since this is highly probably specific only to podman, I'd say it's niche problem, and I would kindly ask you to use either our devel vagrant box or any RHEL VM.
I'll leave the issue open for somebody like @vinzenz or @fernflower to look at that if they find a time.

[pirat89]

@Honza0297 Do you mean, that you expect an output from the actor to see on stdout?
--print-output
Is it what are you looking for?

[Honza0297]

@bocekm OK, that is probably the best solution.
@pirat89 Unfortunately not. I expect to see some debug info and/or status messages. And --print-output does not work either.

[pirat89]

@Honza0297 Ok, in that case there is really bug hidden inside I guess.
