TITLE: Month-long Ubuntu commandline/sysadmin course starting
This course restarts the first Monday of next month. Based around Ubuntu 20.04 LTS, it's free, and daily lessons appear in the sub-reddit r/linuxupskillchallenge - which is also used for support/discussion.
Has been running successfully now every month since February 2020 - more detail at: https://LinuxUpskillChallenge.org
Any feedback very welcome.
