"Little" Problem....

Now i have lerned tu use the Upgrade Tool.

After a long update to jessie and kernel update, the tool give me six files where the installed version is newer then version in the repository.

sudo apt-get -s upgrade:

Terminal

Use 'apt-get autoremove' to remove them.

The following packages will be DOWNGRADED:
