Monero installation error.

E: /tmp/apt-dpkg-install-eQz7GH/9-monero_0.17.2.0+~0+20200826-1_amd64.deb: trying to overwrite ‘/usr/bin/monero-blockchain-ancestry’, which is also in package monero-gui

I just installed Monero on Debian with no problems.
However, I did not understand how to run it.

Monero is installed on Debian but does not work.

I was able to run Monero in a different way.

1 issue = 1 forum thread please. Installation issues are different from issues starting/using.

As for installation of Monero in Whonix, no need. It’s installed by default.
