Practice labs for three more guides:

Using Linux Terminal: 12 chapters
Ubuntu Desktop: 15 chapters
Ubuntu Server: 11 chapters

Each one passes on Ubuntu 24.04 with ufw off and with ufw on: untouched 0%, solved 100% after a reboot, and 0% after reset and start again.

Also:

New sshd_restart helper in lib/lab.sh. On Ubuntu, restarting both ssh.socket and ssh.service, or doing it too often, trips the service's start limit and leaves nothing on port 22. The helper clears the counter, restarts only the socket, and checks that port 22 answers. LFCS 2.4, LFCA 4.1 and LPIC-3 332.1 now use it, and they pass on all four test systems.
The labs for Terminal 2.2 and 3.1, Desktop 2.1 and Server 2.2 now match fixes made to those guides.
