Post-installation issues

[ghost]

I have a few issues with the current version of cnchi, something that I've never seen in the past (I've tried several times for a few days and I always see these same error messages).

After cnchi executes grub-mkconfig I see:

2019-03-23 11:11:26 [WARNING] Error running ['/bin/pidof', 'grub-mount']: b'' (grub2.py:265)

and after a few minutes of delay:

then, somehow it thinks the connection is not working anymore (but at this point all packages are correctly installed):

(...long list of "download failed" removed...)

After rebooting, everything works fine.
