Special thanks to stoppy98. i managed to successfully install vivaldi.
this is what i did.
followed the steps as below
mkdir ~/Documents/elive_repos
mv /etc/apt/sources.list.d/* ~/Documents /elive_repos/
nano /etc/apt/sources.list
add these lines to the file:
deb http://ftp.it.debian.org/debian/ jessie main contrib non-free
deb-src http://ftp.it.debian.org/debian/ jessie main contrib non-free
Moveout of X11, so open a terminal (ctrl+alt+f1) and kill lightdm (or whatever your desktop manager is)
/etc/init.d/lightdm stop
then update apt and install the needed library updates:
apt-get update
apt-get install libc6 libc6-dev libc6-dbg
then installed vivaldi as i had downloaded the recent deb package earlier
dpkg -i [downloaded vivaldi package.deb]
then bring elive to status quo…
rm /etc/apt/sources.list
mv ~/Documents/elive_repos/* /etc/apt/sources.list.d/
rmdir ~/Documents/elive_repos
apt-get update
Thanks a lot and i am now posting this from vivaldi.
