I have downloaded the latest version (13) of Teamvier directly from the website and now have my .deb file. When I double click this file and click the "Install Package" option, it asks for my sudo password, but I then get an error of -
Please check your installation medium and make sure your apt-cache is up to date
I opened terminal and ran
sudo apt-get update
Then attempted to install again, but I received the same error. What must I do in order to succesfully install this program?
