Fix ubuntu apt-get and release upgrade errors

Fix fetching updates:

When you get “Unable to fetch some archives, maybe run apt-get update or try with –fix-missing?” error do this:

cd /etc/apt
mv sources.list sources.list.old
lsb_release -a
sudo cat sources.list.old |grep RELEASECODENAME |grep -v "#" |sed 's|us.archive.|old-releases.|g' >> sources.list

(del and retype >> in console if error occures)
