Ubuntu 16.04LTS

I will freely admit that I’ve been putting off upgrading my Ubuntu 14.04LTS boxes to 16.04LTS. In a previous post, I wrote about my battle with getting the Ubuntu desktop to be usable in the way I wanted it. Having tried this out on 16.04LTS, I realised that I’d have to change the way I work.

I am two weeks in to running the new upgraded system and I wish I’d gone through the pain earlier. Making the Unity Launcher smaller, getting used to the menu bar in the top row of windows, and the close, minimise and maximise buttons landing in the top left of the screen when maximised – none of those took particularly long to get past.

On previous installs, I’ve wanted shortcuts to the common applications at the top of the screen by the clock, but I’ve locked these in to the Unity Launcher – and there’s more space for them.

The only irritation that’s still there is resizing terminal windows. It takes a while to re-learn that I don’t have to be precise with the cursor positioning to change the window size. And that’s it.

Ubuntu 16.04LTS, you are forgiven – I thought you were going to be a nightmare, but you’re lovely. And when I unplug one of my monitors from the graphics card, you put everything back on the screen still plugged in. That’s awesome!

Citrix Receiver and CA support

On installing an Ubuntu 16.04 desktop from scratch and putting Citrix Receiver on it, I found I couldn’t connect to one of the servers that I need to for work. The strange error suggested that the Citrix client doesn’t trust the VeriSign Class 3 Public Primary Certification Authority – G5.

This seemed confusing at first – I have the CA certificate in /usr/share/ca-certificates/mozilla. A quick look at where Citrix Receiver installed itself quickly found what was going on.

Citrix Receiver only has a handful of CA certificates installed in /opt/Citrix/ICAClient/keystore/cacerts, so if you’re connecting to a server with an SSL certificate other than the dozen or so in here, simply copy the .crt or .pem file and you’re sorted.
