I don't agree with this : you install the package but you don't check depedencies...
I think it would be better if you do that :
1) Open a terminal and go in the folder containing the .deb with cd command (if you want to know more about it, type man cd )
2) Type sudo dpkg -i the_downloaded_file.deb (install the .deb package)
3) type sudo apt-get -f install (install dependencies)
Then it will be ok
I hate Chrome but love chromium. My goto browser would be Firefox for sheer number of customisations available in the app store. If your PC has enough horsepower use Kubuntu or else Xubuntu or Lubuntu which are fairly lightweight. One thing I like about Linux Distros is, if you don't like one, you can try several different distros which perhaps suits you.
As a Windows user I managed to sandbox Chromium with Firejail and AppArmor on top of its own Sandbox in Xubuntu
I decided for Solus with budgie desktop, because most Ubuntu based distro's could not handle an AMD GPU (A4 5300) which was used by an older relative.
On Solus FireJail is also available (with its GUI frontend), but I choose for Chromium (in stead of Firefox + Firejail) because Chromium launches a lot faster (Chromium with its build in sandbox lanches < 1 second, while Firefox with firejail takes > 3 seconds).
