Ubuntu server 18.04 LTS is a rather popular linux OS for servers.
Unfortunately, it doesn’t come without its problems. For example, the current version of stunnel – an SSL tunnel – is woefully outdated.
It seems that although Canonical is aware of the problem, they have no intention of fixing it!
Fortunately, there’s an easy workaround that’s much simpler than you might think…
ImageMagick is great. It allows your web app to process, resize, filter, and do all kinds of other nifty things with images.
Not so long ago, ImageMagick 7 was released. One of the big new features was full support for WEBP images, the new image format from Google.
Now, you might think it’s easy to just upgrade to ImageMagick 7. If you’re using a linux OS like Ubuntu, you just apt install and you’re done, right?
If you use Ubuntu Desktop, using a USB stick is a piece of cake. You just plug it in, read/write files, and yank it out again.
But what about Ubuntu Server?
Try the same thing, and you end up with a USB stick that can only be accessed by root. Well, that’s probably not what you want!
There are several ways to solve this problem, but by far the easiest – believe it or not – is to add a touch of Windows…
If you’re running Ubuntu or another linux shell in Windows 10 via WSL (Windows Subsystem for Linux), you’ve probably wondered about using cron.
Cron is super-handy for doing things, like, running a backup.
You see, as useful as WSL is, it stores all the linuxy files in a way that is not exactly easily backup-able by File History or anything else… as far as I can tell.
Worse yet, even when you try to set up a cron job to run a backup, it doesn’t work!
What to do, what to do?
In the olden days, there was only “Bash on Ubuntu on Windows 10”. This little gem gave you something like reverse WINE.
You got an Ubuntu linux install that’s running on top of the Windows kernel – with full file system access, the ability to install and run all kinds of linux command-prompty stuff like git, and even graphical linux apps like gitk.
Fast forward a few years, and things have changed…
What if you’re still running Bash on Ubuntu on Windows (Ubuntu 14.04) and you want to upgrade to the latest Ubuntu 16.04 without reinstalling everything?
Or, what if you want a different flavor of linux?
You may have heard about “Bash on Ubuntu on Windows”. If not, you can check out my post on Bash for Windows 10.
First, you’ll need to make sure you have the Windows 10 Anniversary Update, which you’ve probably received automagically by now.
Then, you’ll need to manually install Bash on Ubuntu on Windows to get your bash prompt.
When you’re done, you’ll probably listen to Microsoft when they say “no GUI stuff!” on bash… But actually, you can set yourself up with a lovely development environment including git – and even gitk – right in Windows.
And it’s much easier than you might think…
This summer, Windows 10 will be 1 year old. Microsoft recently announced that they’ll be releasing another “major” update for their latest OS around this time.
Most of the new features are nothing terribly earth-shattering. Probably the most impactful change to most users will be a slight modification to the Start Menu.
For power users, however, they’ve got something rather big planned: Windows 10 will soon include the Ubuntu Linux Bash shell (probably as an optional app/download).
What in tarnation is going on here?!
If you have a dual-boot setup on your computer involving some flavor of linux, at some point you will most likely encounter a problem with GRUB, the linux bootloader.
For example, maybe you used a tool like Paragon Hard Disk Manager Suite to resize your OS partitions. Then you tried to reboot, and you got a GRUB error message followed by the GRUB rescue prompt.
There are several ways to reinitialize GRUB, and most of them involve live CDs and mounting partitions and all kinds of other tricks that will probably make you crazy unless you’re a command-line commando in linux.
Well, I don’t mind the command line, but I also have better things to do.
Fortunately, there is a MUCH easier way to save the day: Boot-Repair!
If you’re using Ubuntu Server 10.10 and you get the upgrade notice for 11.04 “Natty Narwhal”, you might want to hold off a bit before taking the plunge and typing “do-release-upgrade”.
It seems there is a rather severe problem with GRUB 2. If you have a RAID setup – and even if you don’t – GRUB may not load at all upon reboot, leaving you with a bricked server.
There doesn’t seem to be a fix for it. In fact, I do believe the name of the release should be changed to “Nasty Narwhal”.
Here’s the scoop.

I’m going to assume that you know how to do some basic stuff in Linux. In other words, if you don’t know what a command line is, or how to traverse directories, this might not help you much.
I should also note that my preferred flavor of Linux is Ubuntu. These commands will work on Ubuntu, but I can’t make any guarantees for other distributions. Best to just try them out and see what happens!
Without further ado, here are some more of the top linux tips and tricks that I have gathered over the years…
