Chrome Extension will not install, no errors

[FossPrime]

I've looked in the console, is there any other place I should look? I have both Chrome Beta and Chrome stable installed and it won't install in either. I'm running Chrome 43 and 44 on Fedora 21. I also tried installing in another user profile, still won't install.

The only message I get is An Error Has Occurred: There was a problem adding the item to Chrome. Please refresh the page and try again.

The python part installed perfectly.

Update: It also won't install on my Fedora 22 workstation. Might be a linux compatibility regression.

Same problem encountered at Linux Mint 17.1 with Chrome 45.0.2454.101 (64-bit)

Duplicated over at #35 - an issue with the app/manifest.json only containing Windows and Mac toggle-tamper shortcuts:

"suggested_key": {
                "windows": "Ctrl+Shift+P",
                "mac": "Command+Shift+P"
            }

Looks like multiple pulls including #37 ready to fix, manual fix here: https://github.com/dutzi/tamper/issues/35#issuecomment-170875075

Adding the "linux": "{shortcut}" entry fixes the issue.

At least chrome store now displays a message about the error

There was a problem with the download. Please contact the developer or try again later.
