Allesandro, I have uploaded this for you with the following changes:

- I adjusted the version number to 2:0.8-1ubuntu1
- I included LP: #2070025 in debian/changelog to automatically close this bug when the package migrates from oracular-proposed to oracular
- I ran `update-maintainer` from ubuntu-dev-tools to update the Maintainer field in debian/control for a Ubuntu-specific upload
- I added the Forwarded field to the patch as a basic implementation of https://dep-team.pages.debian.net/deps/dep3/

Could you follow up by proposing your work here to the Debian maintainer?

Thank you for helping to make Ubuntu better.

I have unsubscribed ubuntu-sponsors. Feel free to resubscribe if you have something else that needs to be sponsored.

BTW you linked bug #2070025 rather than this bug #2070057
