$ sudo apt-get install libjpeg-dev $ sage --pip install --no-cache-dir -I pillow
Then restart Sage and try running your code again.

To install Avro Phonetic on Ubuntu 16.04 (32/64-bit), copy and paste the following commands into your gnome terminal(Ctrl+Alt+T):
wget "https://github.com/maateen/avro/releases/download/v2.0/avro_2.0-1_all.deb" sudo dpkg -i avro_2.0-1_all.deb
If you get any dependency errors, then also run the following command:
sudo apt-get install -f
I hope, all is well now and the installation has been finished. Go to System Settings -> Language Support from Unity Launcher Look at the Keyboard input method system Select IBus and close the window.
After this a “reboot” is required. Now go to System Settings -> Keyboard -> Text Entry. Search and add Avro Phonetic as input source. That’s all.
If you are experiencing the “low-graphics mode” error when trying to login, follow the instruction below :
Issues with Nvidia or AMD/ATI graphics
This happens when a driver has a problem installing correctly (Most cases). For this do the following:
- Boot PC leaving SHIFT pressed to make the GRUB Menu show.
- Select Recovery Mode which will continue booting correctly until the Recovery Menu appeares.
- Select from the recovery menu failsafeX.
- In some cases failsafeX will load fine (You lucky dog), for others (Me) it will give an error along the lines of “The system is running in low-graphics mode” and will stay there forever. When this happens, press CTRL+ALT+F1 to go to the terminal. Type in your Username and Password.
- Reinstall the drivers depending on your case:
sudo apt-get install nvidia-current – More stable/tested version
sudo apt-get install nvidia-current-updates – More up-to-date version
The simple way is to
sudo apt-get install fglrx. If this does not work keep reading.
Go to AMDs support site and download the driver you need. (If you have a newer card, you may want to download be the latest beta driver instead of the stable one. You would need to compare release dates and read through release notes to find out which driver version supports which chips.) Put the downloaded driver in some folder and rename it to “amd-gpu.run” to simplify name. Go to the folder where you downloaded the file and type
chmod +x amd-gpu.run to give it Executable Permission. Now just simply run
./sh amd-gpu.run and follow the onscreen steps.
After rebooting all problems should be solved. If you test ‘Additional Drivers’ with a problem like this it will finish downloading the package but then it will give an error. It also gives the same error if you use ‘Software Center’ and ‘Synaptic’. The only way was to go to the
failsafeX option and do the workaround about changing to the
tty1terminal and doing it via command line.
Note that if the problem occured after installing an unsupported driver from the amd site then you may have to first delete the driver you had installed. For this, run in the tty session (i.e) in the terminal screen you get after pressing CTRL+ALT+F1 :
sudo aticonfig --uninstall
(If this command didnt work then check this site . Look under the “Uninstalling the AMD Catalyst™ Proprietary Driver” heading.) After doing this, you may reboot with the command :
sudo shutdown -r now
Now you must get back access to the Unity desktop(Of course with the AMD driver uninstalled). Then you can get to this site which clearly helps in choosing the right AMD driver for your System specifications. Also read the release notes for the latest driver for your graphic card(Especially check if your system satisfies all the system requirements). Then after downloading your driver installer(the .zip file) get to this site and follow the instructions to install your driver. Your driver must be installed and it should work successfully.
I also need to add that I do not recommend downloading the Drivers from the Nvidia site since they:
* Might create additional problems with Ubuntu * Are not updated automatically * Are not tested thoroughly in Ubuntu
Always use the
nvidia-current package or the
nvidia-current-updates one. These are tested and approved already for the Ubuntu version you are using and will give less errors and incompatibility bugs.
Issues with Intel graphics
For Intel it is recommended to do the following after doing all the steps mentioned above but before installing anything (When you are in the Terminal). You can choose Xorg-Edgers which is a PPA that brings many improvements, latest video drivers and more:
Warning: This PPA is very unstable for some things. So do it with that in mind.
sudo add-apt-repository ppa:xorg-edgers/ppa -y
sudo apt-get update and you should receive several updates. X-Swat currently does not have Intel drivers in the latest versions of Ubuntu.
