I copied and pasted line 1 to terminal
I entered my password before entering line 2:
wget -q -O - https://dl-ssl.google.com/linux/linux_signing_key.pub | sudo apt-key add -
Terminal indicated the download done.
sudo apt-get update
I rebooted, and discovered updates available, including google-chrome-stable
Clicking on install began the download (after entering my password).
No problems occurred.
I'm just wondering....
.... does ubuntu clean up its old files (made redundant thru updates)?
This has been quite a big download at 95Mb...... and we get updates every week.
Should I be doing some housekeeping?
