Rebuild Synaptic Database
Problem : Synaptic has seemed to quit working.
Synaptic loads up but doesn't load the list and the menu's are grayed out.
Reason - It could be that the Synaptic database is corrupted. Solution - Open a terminal and enter these commands:
[<you>@localhost ~]$ su <Then press enter>
Password: <Enter the root password>
Remove the corrupt database:
[root@localhost <you>]# rm -f /var/lib/rpm/__db.*
<Then press enter>
Rebuild the database:
[root@localhost <you>]# rpm -vv --rebuilddb
<Then press enter>
You'll see a lot of text scroll by, this may take sometime to complete. Let it finish!
Check for duplicate installed packages:
[root@localhost ~]# dupeclean
<Then press enter>
Clean out apt:
[root@localhost ~]# apt-get clean
<Then press enter>
[root@localhost ~]# apt-get autoclean
<Then press enter>
Close the terminal and try Synaptic again.
