SHA2 mismatch on gdal-framework install

[nsonnad]

Hello. I'm attempting to install QGIS. brew cask install qgis tells me I need gdal-framework

And I get the following error.

❯ brew cask install gdal-framework                                                                                                                                               <<<

Running brew update does not fix the issue. I am on Mavericks, 10.9.2. Thanks.

Thanks for reporting the mismatch. It was fixed in #6335.

Checksum changed again:

They seem to be updating the distribution at the same URL for patch versions. We will change the cask accordingly, but it will still be prone to breaking.

And sure enough it's changed again.

@ndr-qef Given that the SHA has changed again, can I submit a PR to fix it? Or did you have another strategy in mind for this cask?

[tapeinosyne]

Thanks, @lukehorvat, but updating the sha256 value will be unnecessary. We have reintroduced the option to skip checksums even in versioned Casks, which is a better solution for gdal-framework.
