Upgrading the Ubuntu Server Kernel
If you run an Ubuntu-based server (as most of the world does) you should know that keeping the server up-to-date is important for security and stability. Occasionally certain kernel updates will come through that won’t get installed. Instead, you’ll see this message:
The following packages have been kept back: linux-generic linux-headers-generic linux-image-generic
Here’s how to install these updates safely.
Get Emailed When an Ubuntu Server Needs a Reboot
When your Ubuntu server needs to be rebooted, say after a kernel update, the file

Here’s how you can get an email when a reboot is needed saving you the time of manually checking.

Dell XPS 13 Developer Edition Firmware Update Fix
I’m running Ubuntu 18.04 on a Dell XPS 13 Developer Edition, model 9350 (though people have had this issue with 9370 as well). Every couple days Ubuntu Software Center opens up telling me that there is a firmware update. Specifically it says, “Thunderbolt NVM for XPS 9350”.
Clicking the “update” button to the right does nothing. Clicking the “update all” button at the top fails as well. Here’s how I got my firmware update for my XPS 13 to successfully install. Hint, it’s the command-line to the rescue as usual.
Configure Static Networking on an Ubuntu 18.04 Linode Server
Ubuntu 18.04 now uses
netplan together with
systemd to manage networking.
No longer do we edit the
/etc/network/interfaces file in order to configure static networking.
At the time of this writing (September 10th, 2018), Linode has static networking instructions for Ubuntu 17.10, which is EOL’d, but not Ubuntu 18.04 specifically.
More importantly, while the 17.10 instructions do work, it’s not the recommended way according to Ubuntu and most websites I’ve visited around the Internet.
Here’s how I configured my Ubuntu 18.04 server on Linode.
