I can reproduce the error msg if I do a shallow clone with no history

$ cd qemu
$ git describe --match v[0-9]*
v6.1.0-171-g5e8c1a0c90

$ cd ..
$ git clone --depth 1 https://gitlab.com/qemu-project/qemu/ qemu.new
$ cd qemu.new/
$ git describe --match v[0-9]*
fatal: No names found, cannot describe anything.

but the odd thing is that I think we should have been hitting the
problem frequently if it was related to git depth. This job passes
fine in current CI pipelines and my own fork.

Regards,
Daniel
