This problem always seems to happen to me on a new install of Xubuntu on my machine.
I am running Xubuntu 16.04.3 and using GNOME Software version 3.20.5.
This is on a fresh install.
I just ran
sudo apt-get update && sudo apt-get dist-upgrade.
I downloaded the latest version of Google Chrome browser. Then I double click it and it opens in GNOME software. When I double-click install, it gives me a progress bar for a second or two, then resets the install button. I keep mashing install, but the same process repeats, and Google Chrome does not install.
What should I do?
