Ensure that you see no results. Change to the directory containing the Debian upgrade packages. Step 8 user@host:~/sca$ cd /opt/cisco/sln/install_upgrade/sca sudo dpkg -i * Install all Debian packages in the directory. Step 9 user@host:/opt/cisco/sln/install_upgrade/sca$ sudo dpkg -i * dpkg -l 'ciscosln*' user@host:~/sca$ dpkg -l 'ciscosln*' List all installed Debian packages that start with ciscosln.
