Fail to start Julia in Juno. `execvp(3) failed`

Samesies. On Linux Mint 19. Did get an error during installation:
Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-install-8yo3kxsm/functools32/
from which the installation continued fine.

Executing Juno, I get the following note:

jacob@Plato:~/julia/JuliaPro-0.6.3.1$ ./Juno
bash: cannot set terminal process group (-1): Inappropriate ioctl for device
bash: no job control in this shell

That said, Atom loads fine for general editing. and IJulia works fine from jupyter notebook. Edit: the REPL works fine from terminal. It works even better now that I added the folder to PATH and made it executable. Still no joy inside the Juno REPL.
