My initial problem came when I tried to install:
sudo snap install juju --classic
During the Canonical Operators Day training session, which Repeatedly Returned an error for exceeding time…
I rechecked my system (Linux Ubuntu installed on Windows through Oracle VirtualBox) allocations.
I noticed my CPU allotment was only one (1) so I increased CPU to three (3) CPU’s (and removed boot from floppy disk) and used
sudo snap install --classic juju
Juju 2.8.6 from Canonical✅Installed
