Update ubuntu system clock (ntpdate)

Did you notice that the system clock on your Ubuntu server is wrong? On a production server this might not happen, but on a staging server (or on a WSL instance) the date/time can dift. Here’s how to fix it:

First, ask your server what time it is (so you can have a baseline)

$ date
Thu Mar  4 12:30:02 PST 2021  

If that seems wrong, you’ll want to run ntpdate…but first make sure it’s installed:

$ sudo apt install ntpdate

Next, run the command to update the time

$ sudo ntpdate time.nist.gov

# 5 Mar 10:58:20 ntpdate[11619]: step time server 132.163.97.3 offset 80783.696700 sec

Wow, I was off by over 80,000 seconds, which is 1,346 minutes or 22.4 hours!

Now that it’s been fixed, let’s check the date/time again:

$ date
Fri Mar  5 10:58:26 PST 2021

Perfect!

WSL2 – Adding distro not in store

What if you wanted to add an older linux distro to your WSL2 bullpen? Visiting https://docs.microsoft.com/en-us/windows/wsl/install-manual#installing-your-distro will show you a large number of options where you can download the appropriate .appx file.

This will cause the <distro>.appx packages to download to a folder of your choosing. Follow the installation instructions to install your downloaded distro(s).

If you’re using Windows 10 you can install your distro with PowerShell. Simply navigate to folder containing the distro downloaded from above, and in that directory run the following command where app_name is the name of your distro .appx file.PowershellCopy

Add-AppxPackage .\app_name.appx

If that doesn’t work as expected, you could try any of these links that will get the distro from the Microsoft Store

he following links will open the Microsoft store page for each distribution:
