Description of issue

brew upgrade proton-pass is failing with

Error: Download failed on Cask 'proton-pass' with message: Download failed: https://proton.me/download/PassDesktop/darwin/universal/ProtonPass_1.35.0.dmg

The reason I submit is that a) a bunch of other casks successfully upgraded and b) I am able to download the dmg using my browser no problem, only homebrew is failing to download it.

Command that failed

brew upgrade proton-pass

Output of command with --verbose --debug

Proton Drive will likewise fail.

Downloading protonvpn work but not proton-mail and proton-drive for me too right now!

[martinheidegger]

The URL changed, the new URL seems to be: https://proton.me/download/pass/macos/ProtonPass_1.35.0.dmg

As mentioned in #253579 (review), this seems like an upstream issue (i.e., an issue with the proton.me servers). I initially received error responses when testing proton-drive, so I tried adding a referer and then also switched the user agent and it continued to error. The download URL worked in my browser but making a request with the exact same headers using curl failed (installing or updating a cask uses curl for network requests).

It wasn't until I switched my IP address a few times that the requests started working reliably and without any modifications to the casks. This issue affected both the dmg file and the livecheck block URL and both worked for me afterward. However, I can't be sure whether it was an IP address issue or a coincidence of timing. Either way, I opened a PR to update proton-drive to the latest version and bring the asset URL up to date in the process: #253696

I've merged a PR to update the proton-pass URLs (#253579) but that will take a little time before it's included in our JSON API data. Similar to the proton-drive issue, the existing URLs and the updated URLs both work for me when I tested them, so these changes may not have a material impact on this issue.

I checked the protonvpn cask and didn't see anything that should be changed. Similarly, the proton-mail-bridge cask downloads from GitHub (not proton.me), so that should be fine.

After the proton-drive PR is merged, I think that's all that we can do on our end. Things seem to be working at the moment (at least for me) but there's no guarantee that will continue to be the case. If the issues continue in the coming days, then that's something you should discuss with Proton, as we've done what we can and we don't have any control over upstream server behavior.

For proton-drive they have added a new update channel which could be causing issues. I think the stable channel will need to be updated in the cask.

See https://proton.me/download/drive/macos/appcast.xml

I see what you mean. The cask was recently updated to the gradual-rollout release, 2.11.1, as that was the newest version in the appcast. I'll update the livecheck block to use the stable channel and downgrade the cask to the latest stable version (2.10.3), as that's what the upstream download page serves users (#253924). Thanks for the heads up.

No worries. Happy to help!
