Ubuntu (32/64-bit)
1. Please run these commands from the terminal. Never forget to be in relevant directory.
sudo apt install gjs gir1.2-ibus-1.0 libibus-1.0-5 libibus-1.0-dev ibus-gtk ibus-gtk3 ibus-clutter ibus-qt4
wget "https://github.com/maateen/avro/releases/download/v2.1/avro_2.1-3_all.deb"
sudo dpkg -i avro_2.1-3_all.deb
I hope, all is well now and the installation has been finished.
2. Go to System Settings -> Language Support from Unity Launcher
3. Look at the Keyboard input method system
4. Select IBus and close the window.
5. I believe that you need to restart IBus to make everything work fine. Try the following command:
ibus restart
6. Now go to System Settings -> Keyboard -> Text Entry
7. Search and add Avro Phonetic as input source.
8. If you still can't use Avro, please reboot your PC and try from 2 again. That's all.
