I have installed
Open_Source_Complete_Linux_Installer_28072013.apk on my jolla but when I choose img ubuntu file
I have this error:

Unable to find terminal APP.

Because there is no android terminal on my jolla.

How can I resolve this error?

EDIT:

I have installed:

Terminal Emulator_1.0.52.apk on my jolla.

Now it works.

But I need to have the su password?

My error:

cd /home/nemo/ubuntu 12.04
/system/bin/sh: cd: bad substitution
$ su
Password: ??????
