Any update process requires exclusive access to the update resources and will 'lock' them until finished to prevent other update process being started.
In this case 'apt' has locked the update resources and is preventing another update process starting.
Manual updates, background update checks, package managers are examples which need to lock the resource.
Background checks may be running at any time but commonly run just after boot.
Before running a manual update, any package managers need to be closed to avoid a clash.
Depending on the speed of the connection and the size of the updates, the resource may be locked for significant time.

This condition should self clear once the process completes so sometimes all that is needed is to wait.
If the problem does not self-resolve it is possible that something (like an interrupted update) may have broken the mechanism and more investigation will be required to clear the lock.
