Software Updates is capable of checking for updates and installing them without asking for a password except for kernel updates.

The same is not true for apt-get in a terminal. If you try to apt-get update without sudo you get an error: Could not open lock file /var/lib/dpkg/lock - open (13: Permission denied).

Is there a command you could run in terminal which permits updating without using sudo?

Software Updates uses aptdaemon to do all the work. You can do that from the command line using aptdcon:

Check for updates:

aptdcon --refresh

Install updates:

aptdcon --safe-upgrade
