Have you tried rebooting to see if the error persists?

LDprg commented 7 months ago

I don't think those errors are too much of a concern. Seems just like the error says duplicated names in the service files, which is more of a warning than an error.

You might open one of the service files and look if there are actually duplicated names inside.

@peterhoeg maybe you know what's going on? It seems weird to me since there is no obvious reason why the error appears.

LDprg commented 7 months ago

Also maybe this is related https://github.com/bus1/dbus-broker/issues/339

Another thing is that this issue seems to existed when using dbus demon too, just it doesn't check for duplicates so no one noticed.

kreutzi commented 7 months ago

Its weird doesn't happen on a fresh install though

kreutzi commented 7 months ago

@LDprg i investigated more into this and i keep finding weird errors this is a portion of the output for journalctl -u dbus-broker having invalid username for pulse and no entry for nm-openconnect and invalid configs

@kreutzi did you only experience the errors or are there any other problems (like package not working as intended)?

haven't used this system for that long only 2 days but everything is working i will keep you updated

kreutzi commented 7 months ago

@LDprg @Aleksanaa got some graphical bugs with kde randomly invalidating program executables then i investigated some more but pinpointed at kde

found out two dbus services with the same exec but different names

org.kde.kwalletd5 [D-BUS Service] Name=org.kde.kwalletd5 Exec=/nix/store/18n78qdjgylsz65jv8dp250y6hjcvbp6-kwallet-6.0.0/bin/kwalletd6

org.kde.kwalletd6 [D-BUS Service] Name=org.kde.kwalletd6 Exec=/nix/store/18n78qdjgylsz65jv8dp250y6hjcvbp6-kwallet-6.0.0/bin/kwalletd6

i would guess there are similar examples to this but should this cause the errors i am seeing ?

Aleksanaa commented 7 months ago

I think the reason for this is that the kde6 modules are not handled correctly, and some packages from kde5 are mixed in it

kreutzi commented 7 months ago

Yeah i switched desktops to test and the errors lessened to about 30 errors only about some remaining org.freedesktop packages

LDprg commented 7 months ago

@K900 can you take a look at this seems like an error with kde 6 packages. Likely some old kde 5 packages get included along with the kde 6 ones.

@kreutzi The freedesktop ones are very likely just stuff like multiple file explorers that are installed on the system.

BillHuang2001 commented 6 months ago

I have been using the dbus-broker for around half a year, with both gnome and kde plasma. Although I consistently encounter this error message on every boot, my experience suggests that it's more like a warning. Nevertheless, having this warning message mixed with the log output is quite annoying.

SuperSandro2000 commented 3 months ago

Yeah, those are just warnings. The old dbus just silently ignored it. Has anyone ask idea how we can work around this?

peterhoeg commented 3 months ago

This issue predates the inclusion of plasma6. It's a warning as others have pointed out but it really should be fixed.

kreutzi commented 3 months ago

I came to the same conclusion dbus-broker seems more verbose than the old dbus-daemon.

As @peterhoeg mentioned:

This issue predates the inclusion of plasma6

This is beyond my expertise, even after extensive debugging. Perhaps we could involve some KDE developers?

kreutzi commented 3 months ago

This is an explanation for said errors

Subject: Invalid service file ░░ Defined-By: dbus-broker ░░ Support: https://groups.google.com/forum/#!forum/bus1-devel ░░ ░░ A service file is a ini-type configuration file. ░░ ░░ It has one required section ░░ named [D-BUS Service]. The section contains the required key 'Name', which ░░ must be a valid D-Bus name that is unique across all service files. It also ░░ contains at least one of the two optional keys 'SystemdService' and 'Exec', ░░ as well as optionally the key 'User'. Exec must be a valid shell command and ░░ User must be a valid user on the system. ░░ ░░ A service file should be named after the D-Bus name it configures. That is ░░ a file containing Name=org.foo.bar1 should be named org.foo.bar1.service. ░░ For backwards compatibility, we only warn when files do not follow this ░░ convention when run as a user bus. The system bus considers this an error ░░ and ignores the service file.
