[opensuse-buildservice] extend signkey of project

Hi all, I need help with the extending of the validity of a project's signkey. As far as I know the signkeys will be automatically extended, when they reach their expiry time. I now have several projects, where the repo will not get published. I checked deeper and found the signkey of the project expired. osc signkey --extend terminates with Server returned an error: HTTP Error 400: Bad Request /usr/bin/sign: 256 a closer look in src_server.log shows an additional line self-sig is not made with sha1 Now my call for help: How do I extend the key's validity? I run OBS 2.6.10. Thank you for your input, Stefan -- Stefan Botter zu Hause Bremen
