Daedalus is displaying a red screen message related to your machine time being out of sync.
The time on your computer is not in sync with the network. If the time on your computer is off by more than 1 seconds from Network Time (used by Daedalus wallet), Daedalus wallet will not be able to connect to the network.
Note that the 'Cannot Connect to Network' message can be caused by a number of problems. See 'Cannot Connect to Network' message article for more information.
Note that Linux Ubuntu does not use NPT time by default. NPT time is used by Daedalus.
To fix this issue, you will need to synchronize the time on your computer with a Network Time Protocol (NTP) server. To do this you will need to update the settings of your operating system.
