Failed to open uri while redirectAndSignIn

[pshenmic]

Hello. I have issue on my environment (Ubuntu 18.04) when blockstackjs library trying to detect protocol and handle redirection. Earlier, I tried to set up local blockstack browser which seems to messed up my environment and led to the error above.

Actually, I don't really need local browser feature, I want all my users to authenticate via browser.blockstack.org. I tried to put this url as second argument, but this does not work.

@pshenmic Thanks for logging this issue. @shreyasthiagaraj or @larrysalibra any suggestions for what to do.

@pshenmic You can use the makeAuthRequest method to generate an the auth request token string and then redirect the user to by appending the string to http://browser.blockstack.org/auth?authRequest= and then redirecting users to the result.

As to how to uninstall the protocol handler on Ubuntu, @kantai should be able to help you out!

I've assigned this to @zone117x since he's actively working on protocol handling and can incorporate Ubuntu into his considerations per @pshenmic's report.

@pshenmic were you able to use the makeAuthRequest method per @larrysalibra's suggestion to direct users to the hosted browser successfully?

@zone117x I've also experienced the same "Failed to open URI" having installed then uninstalled the local browser. Do your protocol handling changes (#591) address this case?

[zone117x]

Yes it should fix that situation because it will now always perform an https redirect unless the local browser is actually opened to notify the web app that it's working.

And I believe the iframe method for opening the protocol prevents these type of popups - although that needs testing.

To remove the Ubuntu protocol handler, you should:

1. Remove the entry from your mimeapps.list -- edit the file ~/.local/share/applications/mimeapps.list and remove the x-scheme-handler/blockstack entry.
2. Rename the blockstack protocol handler .desktop file:

mv ~/.local/share/applications/blockstack.desktop ~/.local/share/applications/blockstack.desktop.old 

This will remove any protocol association the OS has with blockstack: URLs.

@kantai This instruction did not help me. I don't have anything related to the blockstack in mimeapps.list and blockstack.desktop does not exist in such path.

@larrysalibra But you said it does not work that way on the blockstack forum. https://forum.blockstack.org/t/callback-is-not-fired-with-blockstack-auth/6857/5

The same happened on different environment (Debian), where I havent even installed blockstack browser any time.
