You are about to add the following PPA to your system:
 Stable Channel of Chromium for Ubuntu, matching the Google Chrome Stable Channel for Linux

IMPORTANT: if you are using the other chromium-daily PPA and are willing to switch to this one, you have to *remove/replace* the other one and *downgrade* chromium as the other one always contains newer versions.

FAQ:
* To have a localized build (for non en-US users), please install chromium-browser-l10n
* To pass flags to Chromium, please don't tweak the launcher, but edit /etc/chromium-browser/default instead
* if the browser crashes, you can get a proper backtrace from gdb by installing the -dbg package. See https://wiki.ubuntu.com/Chromium/Debugging for further instructions.
