I am new in the Ubuntu community and started some months ago. Everything was fine till now. I changed the Software Sources, running apt-get and aptitude with -f and -u --fix-missing, tried the Synaptic Package Manager - no success. Always it failed to fetch some archives. What has to be done to make the system going? <TABLE CELLSPACING="0" CELLPADDING="0" WIDTH="100%"> <TR> <TD> </TD> </TR> </TABLE> user:~$ sudo apt-get upgrade -u --fix-missing [sudo] password for user: Reading package lists...
