If I run with the current version 4 d/watch with the uscan `--debug` option, I see this in the output:

$ uscan --verbose --download-current-version --debug
...
uscan info: File debian/watch converted into << ==EOF==
Version: 5

Source: https://gitlab.obspm.fr/api/v4/projects/imcce_calceph%2Fcalceph/repository/tags

==EOF==

If you just use this, it works fine.

Regarding:

$ uscan --download-version 4.0.5

Is wrong, as there is no 4.0.5 version upstream, it is 4_0_5. That doesn't work on your current v4 d/watch either.

Lastly:

I am not super sure about the --download-current-version failing with the d/watch you pasted above, and did not dig
much into the code or the manpage. If you are unable to figure out, then this could potentially be a bug in uscan
and you should file a bug report against devscripts.

For now, your problem should be fixed. HTH.
