@arubislander So, I can't use apt to install packages in libertine-container? Is there no way I can use apt anyway in ubuntu touch?

@Keneda bash provides us fake sudo privileges, so we need not write sudo, and by entering su it requests a password which I have never set, and thereby it returns su: Authentication failure

When I used dpkg to install the .deb file in the libertine container, I faced this error while using apt-get. I can't use sudo in the bash of the container
dpkg: error: requested operation requires superuser privilege
