Package: docker.io Version: 26.1.5+dfsg1 / 26.1.5+dfsg1-4+b1 Hi all, this is related to https://github.com/moby/moby/issues/49197 - "Cannot connect container to custom bridge network: cannot program address in sandbox interface because it conflicts with existing route".
The upstream moby 26.1.5 uses Go package "github.com/vishvananda/netlink v1.2.1-beta.2". The Trixie-packaged version seems to be using an updated version, "1.3.0" perhaps. But, the "vishvananda/netlink" project didn't follow the "semver" rules in this case - its 1.2.1 release included breaking changes. The cause of the specific issue reported in the moby ticket above is described at https://github.com/moby/moby/pull/48368#issuecomment-2307593543 - and was addressed in that PR (to ship in moby 28.0). Another issue with changes in the netlink package was addressed by https://github.com/moby/moby/pull/48407.
