Ubuntu is currently unresponsive because of an update in progress from 22.04 Jammy to 24.04 noble.  This is taking longer than expected largely owing to the huge number of packages installed and automatic backups of the host server taking place simultaneously.

In the meantime, please consider using debian, mint, mxlinux, popos, or zorin as alternatives.  All of these are derived from the same base and will operate similarly.
