The login screen for the IOTR serves up the following message:
[ 9 updates to install: apt upgrade ]
However, executing either "apt upgrade" or "sudo apt ugrade" displays the following:
E: Could not open lock file /var/lib/dpkg/lock - open (13: Permission denied)
E: Unable to lock the administration directory (/var/lib/dpkg/), are you root?
Please explain what our options are for this process?
