Question [Q] Ubuntu Touch (r79) terminal dont work

I recognized yesterday that after a
phablet-flash ubuntu-system --channel devel --bootstrap
the terminal app is not working correct.

I can type a command but can not press Enter or delete it with Backspace.

Im on a manta (nexus 10) device here.
I also got trouble with my mako device (nexus 4) but i posted that seperately on this forum yesterday.

Any help would be nice.
