@stephane-monnot looks like only vendor.conf got changes, but there are no vendor dependencies updates for ovh. You should run trash (https://github.com/rancher/trash) to pull them in. And on our side, the Drone build should be fixed to catch this type of thing in CI

[stephane-monnot]

Done. I am used to ignore vendor folder in my projects.

@stephane-monnot could you exclude trash.lock from the commit? Otherwise LGTM

[stephane-monnot]

Done. I tried to rebase with master, but I got some errors with the package dnssimple. It seems to be missing.
In vendor.conf, I can see github.com/weppos/go-dnsimple/dnsimple but in the dnssimple provider, the use of github.com/dnsimple/dnsimple-go/dnsimple

@stephane-monnot thanks! I've reverted dns-simple changes, and asked the person to resubmit the PR
