Hmm, was https://www.nixhub.io/packages/opencode recently changed? 🤔
Version 2 is not available anymore. Or was it never available? This would explain why the package was built manually.
I just tried updating on another system, and there I am getting

Found the root cause — this is not a devbox code bug, but devbox's package catalog currently points
opencode 2.2.5at a nixpkgs rev that contains a packaging regression.devbox updateresolves foropencode@2(viahttps://www.nixsearch.com/v2/resolve?name=opencode&version=2, per-systemrev: 9d3b8db48266c17be0b5f9c6360c3ecfbac3d1f5,last_updated 2026-11-03T19:55:20Z) packages theopencode-node_modules-2.2.5fixed-output derivation with a singleoutputHash=sha256-xfOVcw1+waLVNhFDwzOtzxrUSQEogvn88YomydOlhwc=.--frozen-lockfile)bun installproducessha256-prx9dX7kUvs/E3zopkaPk5LXh3xJAy5sZeum/W8L7cA=, hence the mismatch on every Linux machine.

Hi @mikeland73, sorry for tagging but you seem to be the most active dev here. 😺
Any chance to get this merged? Upstream fixed this five days ago, so I guess that you just need to poll it.
I couldn't find any public nixsearch/nixhub catalog repo, otherwise I would have created a PR to get this fixed. Thanks for your help!

This should be fixed now. devbox resolved opencode 2.2.5 to nixpkgs
9a6cbf47, which still had the broken node_modules hash. The upstream fix (NixOS/nixpkgs@c399e1b7) kept the version at 2.2.5, and the search index picked it up on Nov 6:opencode@2.2.5now resolves to4fe25e12, which has the corrected hash. Please re-rundevbox global update opencodeand let us know if it still fails.The index is open source at https://github.com/mikeland73/devbox-search if you want to file issues or PRs there.

Thanks @mikeland73, this worked! And great that there is a public
devbox-searchrepo, I had missed it. Thank you for the hint!What needs to be done to get V2 published/listed on https://www.nixhub.io/packages/opencode?

devbox is no longer using the nixhub back end (which is closed source). You can use https://www.nixsearch.com/search?q=opencode which shares the same search as devbox (that site uses the source code from the devbox-search repo)
