Hello,

I'm running kde on debian stable and daily updates and one of the last updates caused some misbehaviour of kmail.
As I use kmail for many years without major issues, I did not care much about configuration/updates ...

Now it happens, that 3 out of 4 reboots kmail is blocked by a shaded rectangle telling me, that akonadi does not work.
I really don't know much about kde, kmail and its internals - I'm just a kde user.
So I tried a fresh installation of the whole system, but after mounting my (existing) home directory, its behaviour is as before.
If kmail would fail on every reboot, I would state, that my system is broken. But if it fails only 3 out of 4 reboots ...
... there may be some timing issues, I don't know, how to get rid of.

Looking at the log of kmail, test 10 is the first that fails:

Code: Select all

Test 10:  ERROR
--------

Akonadi control process not registered at D-Bus.
Details: The Akonadi control process is not registered at D-Bus which typically means it was not started or encountered a fatal error during startup.

Test 14 may be interesting too (don't know, whether they are related):

Code: Select all

No resource agents found.
Details: No resource agents have been found, Akonadi is not usable without at least one. This usually means that no resource agents are installed or that there is a setup problem. The following paths have been searched: '/usr/share/akonadi/agents'. The XDG_DATA_DIRS environment variable is set to '/usr/share:/usr/share:/usr/local/share'; make sure this includes all paths where Akonadi agents are installed.


Checking akonadi as a root user results in these outputs:

Code: Select all

Doing the same as desktop user:

Code: Select all

akonadictl status
Akonadi Control: stopped
Akonadi Server: stopped
Akonadi Server Search Support: not available


It says - akonadi server is stopped.
... so I tried to start it:

Make sure your system is set up correctly!


Running qdbus as root fails like akonadictl:

My kde desktop is configured to restore a saved session, which consists of 4 virtual screens and kmail is an opened app on one of these screens. Furthermore the saved session starts krusader and about 15 konsoles

I don't know, how to get rid of the problem.
So if anybody could shine me a light ...

best regards

Reinhard

You can't use akonadictl as root because it needs a local DBus session, which is initiated by your user. When you see these errors in KMail, try, as regular user, to issue "akonadictl restart" in the terminal and report here any output (if too long, use a pastebin service).

Hello einar,

thanks for your attention!

When I powered on my box, it came up with kmail locked.
So I followed your advice ...

Code: Select all

$ akonadictl restart
Akonadi is not running.

followed by a

Code: Select all

$ akonadictl start

Make sure your system is set up correctly!

So I did, what seems to work - sometimes:

Code: Select all

sudo /etc/init.d/kdm stop

and then login on console as root and issue a

Code: Select all

/etc/init.d/kdm start

After login to kdm, kmail works fine

best regards
