Thanks for the issue @ggwpez. This issue should not(™) happen and was fixed already.
I will check again if something changed and triggers this issue again.

Could you please add the output of srtool --version so I test like your system ? (it may be time to add an issue template for that :)).

I think nonetheless that the issue is inside the image.

$ srtool --version
srtool-cli 0.11.0

We are experiencing the same issue using the latest image paritytech/srtool:1.73.0-0.12.0. Any update @chevdor?
