I have installed Google chrome v 77.0.3865.10 (Official Build) dev (64-bit) in Debian buster.
It's not chromium. If that is still OK I did as follows:
Go here and download the dev channel version of chrome:
You should see a file like this in your download directory:
google-chrome-unstable_current_amd64.deb
then install gdebi.
Now run
gdebi google-chrome-unstable_current_amd64.deb
You will get a res
Do you want to install the software package? [y/N]:y
/usr/bin/gdebi:113: FutureWarning: Possible nested set at position 1
c = findall("[[(](\S+)/\S+[])]", msg)[0].lower()
dpkg: warning: 'ldconfig' not found in PATH or not executable
dpkg: warning: 'start-stop-daemon' not found in PATH or not executable
dpkg: error: 2 expected programs not found in PATH or not executable
Note: root's PATH should usually contain /usr/local/sbin, /usr/sbin and /sbin
Then run
echo $PATH
Then run
export PATH="$PATH:/sbin"
Then run
gdebi google-chrome-unstable_current_amd64.deb
This will cure the pesky dpkg PATH errors
then run
/usr/bin/google-chrome-unstable as user
and it should start up OK.
Cheers
