Kubuntu Adept Installer not working!?

[darkrubysage]

Adept Installer says:

Could not obtain a write lock on the cache, falling back to read-only mode. You won't be able to install, remove or upgrade packages. However, you can still search in the package database and browse packages.
It appears that another process is running, which holds the write lock on the database. You first need to close that program and then restart Adept to gain write access.

What do I do?

Simply, another instance of Adept is already running.
Please check which applications are opened and you should find the first opened Adept.
