What’s going on here? Ubuntu claims it can’t update because it can’t connect to the Internet, but I can ping. A quick websearch tells me to clear out the “updates available” because of some issue I don’t care to research. Try it again! Nope! But throws a clue. Check the date! A-ha! Set the date. But wait, Raspberries don’t have RTC (realtime clock) batteries. I need ntp (network time protocol). I can install that with apt-get, but first, I gotta’ set the date. And before I set the date, I need to set the timezone!
Ubuntu Timezones
If you’re not sure of your timezone, you can list them with:
timedatectl list-timezones
I live on the East Coast of the US, so mine is America/New_York. Here’s the command:
timedatectl set-timezone America/New_York
Next, the date:
root@ubuntu:~# date Wed Apr 1 17:59:09 UTC 2020 root@ubuntu:~# date 10081320 Thu Oct 8 13:13:20 EDT 2020 root@ubuntu:~# apt update Reading package lists… Done E: Could not get lock /var/lib/apt/lists/lock. It is held by process 3274 (apt-get) N: Be aware that removing the lock file is not a solution and may break your system. E: Unable to lock directory /var/lib/apt/lists/
Automation!
Pretty cool. Once I set the date, Ubuntu took over figuring out what’s what by running apt update in the background! I’ll check in later.
Two Hours Later…
Look at what I get after log in:
51 updates can be installed immediately. 0 of these updates are security updates. To see these additional updates run: apt list --upgradable *** System restart required *** Last login: Wed Apr 1 14:33:54 2020 from 192.168.1.10 ubuntu@ubu1:~$
All right! Let’s do this!

Answer “Y” and let ‘er rip!
