We have the same with "az stack sub create ...", tried to uninstall and install and it still fails. Using ubuntu 24.04 shared agents.

We have the exact same problem when running "az deployment group create" using "Ubunut-latest"

ERROR: [Errno 2] No such file or directory: '/home/vsts/work/_temp/.azclitask/bin/bicep'

Looks like a duplicate of #31189. See the workaround.

@benoutram thanks the workaround provided worked

This seems to also happen on Github action runners that before ran fine, ubuntu-latest, even when running az bicep install and az bicep update: FileNotFoundError: [Errno 2] No such file or directory: '/home/runner/.azure/bin/bicep'

We have similar issue for az bicep restore --file , using Microsoft hosted agent

I've tried uninstalling and reinstall bicep, along with the binary path=false command, still no luck.
