Following a crash disk , I rebuild my pc with backup of sources & packets plus /home.
Unfortunately, the restore of my packets didn't works. If 1,2 Gb were downloaded, none of my favorite free softwares are installed !
Here is the procedure,I've followed :
* backup of /home
* backup of /etc/apt/sources.list,
* dpkg --get-selections "*" > MyPackets.txt
* copy of my /home
* add lines of sources not created by the system in sources.list
* sudo dpkg --set-selections < MyPackets.txt && sudo apt-get dselect-upgrade
* sudo apt-get update
an idea ?
