adept problem (on Kubuntu)
 

When I open adept on my Kubuntu Dapper Drake, there is an alert:
Another process is using it (or apt command).
And I can't open adept...
I restarted the OS, but there is the same problem...
How I can resolv it?

You could try the ps command to see if another process of apt or adept is running for some reason..or remove the pid file.

and you can scroll through the processes currently going on. If you find apt or adept or such process running (make sure you aren't running apt or adept yourself), kill it with

where xxx is the process number, or

where yyyy is the name of the process. And if no processes seem to run, then just locate and remove the pid file of apt/adept.

That's not the error message. - People, when you're encountering error messages, do listen to them - and when you're asking for help, please do post them, literally.

The original error message is,
So, just close that other software-install program.

In your own case, you did reboot already - so no conflicting apps should be open. Hence something else went wrong, which left the system in an inappropriate state.
Anyways, with that literal error message at hand, a quick Google search returns:
Thanks

it doesn't work....

It never does. As it never gets catched. Even noone knows what it is. ;)

- What's the output of

dpkg --configure -a

Thank you, riddler01. I had the same issue, and that fixed it.
