Description Xavier Matz 2016-03-02 21:55:58 CET

Description of problem:
trying to start claudia fails with error "dbus.exceptions.DBusException: org.freedesktop.DBus.Error.ServiceUnknown: The name org.ladish was not provided by any .service files"
Indeed, ladish is not a dependency of the claudia rpm package - which is weird, since claudia is precisely a gui for ladish session management. 
Actually, ladish seems to be missing in mageia altogether (i can't find any ladish package), whereas there was a ladish package in mandriva and there is one in fedora. as can be seen here:
http://fr2.rpmfind.net/linux/rpm2html/search.php?query=ladis&submit=Search
Apart from that fact (that there's no ladish rpm in mageia), the fact that the claudia rpm package is missing a dependency to ladish may come from the fact that it is generated by a common rpm of the whole cadence suite - most other parts of which do work without ladish.

Hi,
Yes, this is known and on a long waiting TODO.
If you look in cadence.spec, I added "#TODO: package ladish and add it to Requires here" when I wrote this spec.

I don't remember exactly what stopped me from adding ladish, I think that it needed again other new dependencies. I have to check again, but I'm away from home for 2 weeks and can't spend much time to package those for now.

Comment 2 Timothée Giet 2016-03-29 14:56:01 CEST

Just to let you know, I started looking at packaging ladish to fix this bug.
However ladish has 2 BR that also needs to be packaged first:
-laditools
-flowcanvas

for laditools, I have a (locally) working spec, but for flowcanvas I'm stuck with some build errors. 
If someone can help me packaging flowcanvas, that would help a lot.

Comment 3 Timothée Giet 2017-05-19 10:45:07 CEST

Added ladish in the repository and updated claudia to require it.

Status: ASSIGNED => RESOLVED
Resolution: (none) => FIXED

Comment 4 Conrad Vielson 2020-05-31 19:03:40 CEST

Just encountered that same problem on a current cauldron: 

dbus.exceptions.DBusException: org.freedesktop.DBus.Error.NameHasNoOwner: Could not get owner of name 'org.ladish': no such name

and just as in the original bug report, there is no ladish package as a dependency of claudia and in fact ladish apparently isn't even available as a package in cauldron

Resolution: FIXED => (none)
Status: RESOLVED => UNCONFIRMED

Comment 5 Timothée Giet 2020-05-31 20:04:26 CEST

I guess ladish was removed as part of the removal of python 2...

However, I saw yesterday that falkTX (the maintainer of KXStudio) fixed his ladish package "to work on systems without python2", so the same should be doable in cauldron...

The sources of his .deb package can be found in the list here:
https://launchpad.net/~kxstudio-debian/+archive/ubuntu/apps/+packages

Also, official homepage for reference:
http://ladish.org/

So if someone could bring back ladish in cauldron before the freeze for mga8, it would be highly appreciated as claudia is a tool I use in mga7 (and I'm a bit over-busy these days to look at it).

Thanks Timothée for the work you did. Shlomi has kindly just picked this up, so re-assigning to him for the moment.

It looks as if ladish is now re-instated in Cauldron. And it is a bit early to worry about "the freeze for mga8"!
