How do I obtain the newest stable Debian package files?
sudo dpkg -i ~/Downloads/libgoocanvas3_1.0.0-1_amd64.deb
sudo dpkg -i ~/Downloads/libgoocanvas-common_1.0.0-1_all.deb
sudo apt-get -f install
When I have to install Debian packages (see above) I first have to download them. Let me paste the entire links to these two packages:
libgoocanvas3
https://launchpad.net/ubuntu/+archive/primary/+files/libgoocanvas3_1.0.0-1_amd64.deb
libgoocanvas-common
https://launchpad.net/ubuntu/+archive/primary/+files/libgoocanvas-common_1.0.0-1_all.deb
As can be seen the two respective files are libgoocanvas3_1.0.0-1_amd64.deb and libgoocanvas-common_1.0.0-1_all.deb.
and now the questions
Do I need to use different Debian package versions dependent on my Ubuntu version?
How do I know these are the newest stable versions of each file (related to above)?
Where do I get the "official" latest and greatest files?
