Epoptes

Epoptes service not starting on KDE Neon (Ubuntu 16.04

Asked by Uclio Dinobi

Hi,

I'm not a Python guy, so I'm not sure if the Epoptes service is not starting due to some wrong/unexpected/missing dependency... at the end Neon is just an Ubuntu-based distribution. I tried on two different machines (same distribution) and both yield the same error.

$ (sudo) python /usr/lib/python2.7/dist-packages/twisted/plugins/epoptesd.py
Traceback (most recent call last):
  File "/usr/lib/python2.7/dist-packages/twisted/plugins/epoptesd.py", line 32, in <module>
    from twisted.application import internet, service
  File "/usr/lib/python2.7/dist-packages/twisted/application/internet.py", line 54, in <module>
    from automat import MethodicalMachine
  File "/usr/lib/python2.7/dist-packages/automat/__init__.py", line 2, in <module>
    from ._methodical import MethodicalMachine
  File "/usr/lib/python2.7/dist-packages/automat/_methodical.py", line 34, in <module>
    @attr.s(frozen=True)
TypeError: attributes() got an unexpected keyword argument 'frozen'

Of course I'm using last Epoptes packages (0.5.10-1), tried either the official ones and from the ppa repository.

Any idea about how can the matter be solved ?

Thanks

No answers so far :-(

Looks like I am the only one to experience this... did I miss anything already reported to the mailing list ? No beautiful soul who can give me a little help?

Further info (please let me know if you need something more) I forgot to give related to the packages which seems to be involved :

dpkg -l python-attr -> 15.2.0-1
dpkg -l python-twisted (-bin, -core) -> 17.9.0-1+16.04+xenial+build1
dpkg -l python-automat -> 0.6.0-1+16.04+xenial+build1

I directly tried the "python .../epoptesd.py" command because "/etc/init.d/epoptes start" yields "usr/bin/twistd: Unknown command: epoptes"

Thanks in advance to anyone who can help me.

I haven't seen the KDE Neon distribution.
If this happens in all installations of KDE Neon, then yeah it sounds like a missing dependency. Did you install epoptes with --install-recommends? (e.g. I know Linux Mint has --no-install-recommends by default, opposing the Debian policy).

You could also try coming to IRC, to see the problem live: www.epoptes.org => IRC link.

Hi Alkis,

At the end KDE Neon is just KDE Desktop on top of Ubuntu Xenial LTS.

Here is a complete installation session... hope you can get something out of these info :

$ sudo apt-get install --install-recommends epoptes epoptes-client

Could it be that in a Ubuntu distribution with GNOME (or derivatives) there is a Python package not present in Ubuntu with a different Desktop ? Did you ever try to install epoptes on Ubuntu Server ?

I will give it a try this evening and report about that.

A missing dependency is possible.
I haven't tried to install Epoptes on Ubuntu server.
In proper installations, running the command "twistd" should list Epoptes as a "Command":

# twistd
...
Commands:
    conch A Conch SSH service.
    dns A domain name server.
    epoptes Epoptes Daemon
...

Btw, also please use the Epoptes github issues instead of launchpad questions; since the development has moved to github, there's not much point in keeping the Answers here active.

https://github.com/Epoptes/epoptes/issues

I'll try to disable Answers completely...

Can you help with this problem?
