I have Ubuntu 12.04 LTS and I tried to upgrade to Ubuntu 12.10. When I clicked in the Update Manager Upgrade a message box apeared:

Cannot run the upgrade. This usually is caused by a system where /tmp is mounted noexec. Please remount without noexec and run the upgrade again.

I tried to make /tmp executable in Terminal with the following command:

mount -o remount,exec /tmp /var/tmp

I pressed Enter and I got the following message from Terminal:

mount: only root can do that

What should I do now to make /tmp executable and upgrade the OS?

You need to have root privileges. For this, put sudo in front of the command:

sudo mount -o remount,exec /tmp

When you are asked for a password, just enter your usual user password.
