@ Tv stick;
I need an external SD card with more space. Will get it soon.
What is your internal memory?
Something like 750 mb
Hmm, to small. Could you sent a link with specifications of which exactly TV stick are you going to use?
I have an idea. My samsung phone has an external SD card. I will use that and see how it goes.
I have a Tronsmart MK908.
The wifi sucks a little bit though. I see that the MK908 II has an external Wifi receiver. That would be much better.
You have 8GB NAND FLASH ROM. The same I have and it acts as sd card, but internal. I didn't use any external SD card, all goes from internal.
Alright, let's try it your way xD
I'm wondering how this would succeed though;
" I used small 13.10 image, because I installed it in internal sdcard. Extracted it takes 2GB"
I will let you know
EDIT: The extraction of the file has been completed. You we're right. I didn't need an external SD card.

UPDATE; @Launch Ubuntu; The image set in this profile does not exist! Please use the menu button and change the image name.
But I already have changed the image name like the Youtube video said.
UPDATE 2; When I click at 'Add' at Settings. I can choose the image file myself. But whenever I want to go to the Ubuntu folder. It says; Can not acces SDcard0.
Strange. Try to restart stick. After restart you should wait for around 3-5 min and then try to start ubuntu. Did you installed terminal, vnc viewer and busy box also, which comes with the "simple ubuntu installer" package?
EDIT: Yes, Superuser should be done.
