A soulution for not being able to install or update anything using Muon Software/Updates Manger " in Kubuntu 12.10
The following problems faced me and i wanted to post it to help others if they suffer from it .
- Downloading updates through Muon updates manger was too slow than normal ( about 2Kb/s )
- Can not install any applicaion unless from Terminal
What i did was
1- Downloading updates from the terminal - the download speed was normal - by typing
sudo apt-get upgrade
3-- installing any application through terminal by typing for example
sudo apt-get install kwordquiz
an error appeared and asked me to type
sudo dpkg --configure -a
so i did .
* Thats what i did , and all went well
Notes : after the second step i opened Muon update manger and i found that
linux-headers-generic and linux-image-generic were not downloaded , and when i tried to this message appeared
" Another application seems to be using the package system at this time. You must close all other package managers before you will be able to install or remove any packages. "
although Muon update manger was the first program i opened .
And the same message appeared every time i tried to install any application using Muon Software Center .
But installing applications through went well then .
