`bazelisk completion` is using buildbuddy version to fetch completions

Following https://github.com/bazelbuild/bazelisk#command-line-completion breaks on bb:

$ cat .bazelversion
buildbuddy-io/5.0.373
9.1.0
$ bazelisk completion fish

2026/06/09 08:21:30 could not handle completion command: could not get completion script: could not download completion script: failed to download installer: failed to download installer: HTTP GET https://github.com/bazelbuild/bazel/releases/download/buildbuddy-io/5.0.373/bazel-buildbuddy-io/5.0.373-installer-linux-x86_64.sh failed with error 404

Workaround: remove buildbuddy version to install completions:

$ cat .bazelversion
9.1.0
$ bazelisk completion fish > ~/.config/fish/completions/bazel.fish

hi @nicdumz - which bazelisk version are you using? is this linux or macos?

[nicdumz]

That was 1.27.0. On 1.28.1:

2026/06/11 19:09:05 The `completion` command is not supported on Linux amd64

Which is funny because this is a Linux x86 box:

uname -a
