bicep install/upgrade on aarch64 using wrong binary (linux-x64 instead of linux-arm64)

[ulfandersson]

Describe the bug

Host machine: Apple silicon (ARM, M1-M3) Mac

Inside debian based dev container (mcr.microsoft.com/devcontainers/javascript-node:0-20-bullseye):

$ az bicep install --debug
...
cli.azure.cli.command_modules.resource._bicep: Generated download URL https://downloads.bicep.azure.com/v0.29.45/bicep-linux-x64. from system Linux, machine aarch64, release tag v0.29.45 and target platform None.

Actual result: linux-x64 is used

Expected result: linux-arm64 should be used.

Proposed fix, add or machine == "aarch64" to the if statement here:

azure-cli/src/azure-cli/azure/cli/command_modules/resource/_bicep.py

Line 290 in 7df71d6

elif system == "Linux" and machine == "arm64":

Workaround
$ az bicep uninstall
$ az bicep install --target-platform linux-arm64

partly related issue: #28756 (however, once installed with correct target-platform I have no issue running bicep)

Related command

az bicep install

Errors

cli.azure.cli.command_modules.resource._bicep: Generated download URL https://downloads.bicep.azure.com/v0.29.45/bicep-linux-x64. from system Linux, machine aarch64, release tag v0.29.45 and target platform None.

Thank you for opening this issue, we will look into it.

[stewartadam]

@yonzhan any updates on this? It breaks using Az CLI + Bicep in devcontainers on any Apple-silicon Mac.

[ulfandersson]

@yonzhan Still no update?

[ulfandersson]

@yonzhan Any update on this?

[MShekow]

I'm puzzled why not more people have problems with this...

We are also affected.

@shenglol Could you please help take a look at the Bicep related question?
