brew cask Update or uninstall error: definition is invalid: invalid 'depends_on macos' value: ":lion"

I can't uninstall or upgrade some casks due to a definition error.

F.e. if I run update or upgrade:

brew cask upgrade the-unarchiver  
Error: Cask 'the-unarchiver' definition is invalid: invalid 'depends_on macos' value: ":lion"

brew cask uninstall the-unarchiver 
Error: Cask 'the-unarchiver' definition is invalid: invalid 'depends_on macos' value: ":lion"

I've tried to see if there's something I can edit in the formula but I didn't find anything related to this error.

cask 'the-unarchiver' do

Homebrew cask developers deleted pre-maverics dependencies support due to the high maintenance overhead and it looks like they introduced a bug.

The way to fix it is to run:

/usr/bin/find "$(brew --prefix)/Caskroom/"*'/.metadata' -type f -name '*.rb' -print0 | /usr/bin/xargs -0 /usr/bin/perl -i -0pe 's/depends_on macos: \[.*?\]//gsm;s/depends_on macos: .*//g'
