if you get such a problem, you should do other things before the second setp as follows:
(1) add other source at /etc/apt/source.list 's end:
## Regular repositories
deb
http://http.kali.org/kali kali main non-free contrib
deb
http://security.kali.org/kali-security kali/updates main contrib non-free
## Source repositories
deb-src
http://http.kali.org/kali kali main non-free contrib
deb-src
http://security.kali.org/kali-security kali/updates main contrib non-free
then you input command :
apt-get update
apt-get install -f
you should begin to install libappindicator1 and update
(2) By the way, I add one more point.
on the fifth step, if useing gksu -u xxx, I find that the chrome will happen some problem, other input method is not working as usually. As a result, you should use command " /usr/bin/google-chrome-stable --no-sandbox"
before doing this, you should edit file such as follow:
leafpad /opt/google/chrome/google-chrome or google-chrome-stable
add "–user-data-dir" at end.
good lucky!
