Brand new installation of Ubuntu 22.04
I go to https://www.dropbox.com/install-linux and click on Ubuntu 14.04 - 22.04 (.deb) 64-bit
The file dropbox_2020.03.04_amd64.deb appears in my download directory.
I click on it, expecting Dropbox to install as it does with other linux software
Instead I find archive manager open up offering to extract three files: debian-binary, data.tar.xz, and control.tar.gz
What am I supposed to do next?
