This question already has an answer here:
When I try to launch google-chrome, I get the following message:
Failed to create a ProcessSingleton for your profile directory. This means that running multiple instances would start multiple browser processes rather than opening a new window in the existing process. Aborting now to avoid profile corruption.
I tried to uninstall and reinstall Chrome following the advice here How to install Chrome browser properly via command line?, which did not solve my problem.
How should I proceed?
