Error installing cask anaconda: Cask 'anaconda' definition is invalid: invalid 'sha256' value: nil

[dvyakumar]

Verification

• I understand that if I ignore these instructions, my issue may be closed without review.
• I have retried my command with --force.
• I ran brew update-reset && brew update and retried my command.
• I ran brew doctor, fixed as many issues as possible and retried my command.
• I have checked the instructions for reporting bugs.
• I made doubly sure this is not a checksum does not match / SHA256 mismatch error (do not open an issue before trying to open a PR to fix first).

Description of issue

the command was run on Manjaro OS, x86 arch

Command that failed

brew install --cask anaconda

Output of command with --verbose --debug

I got the same problem with with the google-cloud-sdk cask.

My brew install --cask google-cloud-sdk --verbose --debug output shows a similar stacktrace so I suspect a general problem.

Also discussed in https://github.com/orgs/Homebrew/discussions/6008.

[elephantum]

Is there a workaround to install cask on linux without checking for sha?

[SMillerDev]

If you see this error it means there is no Linux support. I (or others) just haven't had time to fix the blocking. You could add Linux support to the cask with checksums, that would also solve your problem.
