Google Chrome: Error 11 after setting Automatic Updates
Just found this How To Fix Chrome Update Error 11 On A Mac


  
  Open Finder. In the top menu, select Go > Go to Folder
  Enter either of the locations below. If the first location doesn’t come up, try the other:
  /Library/Google/GoogleSoftwareUpdate/GoogleSoftwareUpdate.bundle/Contents/Resources/
  ~/Library/Google/GoogleSoftwareUpdate/GoogleSoftwareUpdate.bundle/Contents/Resources/
  Double click the file called CheckForUpdatesNow.command – the Mac Terminal window will open and execute the command
  Wait until you see the message “[Process completed]”
  Close the Terminal window
  Refresh your Chrome ‘About’ page – the update should complete without showing the error
  


And it really worked for me
