I've tried brew update and deleting the temp file+retrying, same thing

I just made a cask pull request to try to fix this.

Hi, I'm one of the maintainers of Homebrew Cask.

Please run
brew update && brew upgrade brew-cask && brew cleanup && brew cask cleanup
and then
brew update && brew cask uninstall qlmarkdown --force && brew cask cleanup && brew cask install qlmarkdown

If this doesn't fix things, please open up an issue at https://github.com/caskroom/homebrew-cask

@moomoohk This is fixed for me now. Please let me know if it is working for you.

Hey, I've been too busy to follow up on this but I just tried what @adityadalal924 suggested and it looks like everything's working properly.

Thanks everyone

Hi, I do not know terminal much but I Really need to install YakYak, a desktop client for Google Hangouts on Mac. I wish they had made a DMG file, but considering it is only installable via Homebrew, help me with this error please.

@NOTSOGEEKY Don't resurrect old threads. This is a shasum error for yakyak, follow the reporting bugs guide, the solution is there (likely an outdated Cask)

And by guide, I mean https://github.com/caskroom/homebrew-cask/blob/master/README.md

This isn't related to qlmarkdown at all

@jeevabaski
This is a shasum error for devcenter, follow the reporting bugs guide, the solution is there (likely an outdated Cask) - we have step by step directions.
