This quick guide explains the steps to change desktop language for both Ubuntu 18.04 and Trisquel 8.0 to German, Russian, Spanish, Indonesian, and revert back to English. Here I also give an example (Indonesian) in installing manually a Language Pack which by default is not installed so you will understand how to do the same for another languages (Arabic, Japanese, Chinese, etc.). Enjoy Ubuntu and Trisquel in your own language!

Continuing the printing tutorial, scanning is also pretty easy on both Ubuntu 18.04 and Trisquel 8.0. We use one preinstalled program called Simple Scan there. Again, with the same device Canon MP160 printer+scanner (100% compatible with GNU/Linux), this tutorial explains the steps to do. You don't need to install any additional driver on both system to scan with this scanner. Happy scanning!

You can easily re-associate between files and programs to open it on Ubuntu 18.04. Also, you can change the default web browser and mail client if you have the alternatives. For example, to open JPEG photo on Shotwell instead of Image Viewer. To do that: right-click on the file > Properties > Open With > select the program Shotwell available there > Set As Default. Now all JPEG photos will open on Shotwell.

Go to Open With > select the program

Then, if you have alternative browsers, let's take example between Mozilla Firefox and Epiphany Browser (GNOME Web), you can turn Epiphany Browser instead to be the default easily by going to main menu > Default Applications:

Changing default browser

Finally, if you also have alternative mail clients, for example between Mozilla Thunderbird and Claws Mail, you can turn Claws Mail to be the default one by the same menu:

This short tutorial shows how to install Iridium, the privacy and security powered browser, on Ubuntu 18.04. Remember that Iridium is only available for 64 bit, no official 32 bit available.

1) Add the repository key of Iridium:

$ wget -qO - https://downloads.iridiumbrowser.de/ubuntu/iridium-release-sign-01.pub | sudo apt-key add -

2) Add the repository into a new sources.list:

You can add only the first one below. However, the second one is the source code repository and you can add it (and remove the # to enable it) if you need it.

$ echo "deb [arch=amd64] https://downloads.iridiumbrowser.de/deb/ stable main" | sudo tee --append /etc/apt/sources.list.d/iridium-browser.list 

$ echo "#deb-src https://downloads.iridiumbrowser.de/deb/ stable main" | sudo tee --append /etc/apt/sources.list.d/iridium-browser.list

Edited 12 January  2018: thank you Vincent from comment section and Plop Plopesol from social media for correcting my mistake here. I am very grateful for you two!

3) Reload your repository index:

$ sudo apt-get update

4) Install Iridium Browser:
