When after an update of Google Chrome the program doesn't start anymore, as in you can click the icon, but nothing appears, you can try the following:
from the terminal:
google-chrome-stable %U --password-store=basic
Now log in to your Google account and close the program. Now try it again to open it the usual way.
Switch to basic for the password store
basic is chrome's builtin password storage, but it stores password's in plain text.
This is why chrome defaults to using the Ubuntu keyring. They store password encrypted.
To set it to default to use basic try this
copy the google-chrome.desktop file from /usr/share/applications into your home folder applications folder:
cp /usr/share/applications/google-chrome.desktop ~/.local/share/applications
then open gedit (you can open it dircly with the following command:
in gedit Find each of the lines that begin with Exec and add --password-store=basic like so
Exec=/usr/bin/google-chrome-stable --password-store=basic %U
then save and now when you launch chrome you should never be asked for your keyring.
