Package: docker.io
Version: 26.1.5+dfsg1-9+b13
Severity: normal
Dear Maintainer,
* What led up to the situation?
I encountered on some systems duplicate mac addreses for docker
containers.
* What exactly did you do (or not do) that was effective (or
ineffective)?
Removing both containers (that are involved in the conflict) helps (workaround)
ENvironment where this occurs:
debian trixie, docker from debian (26.1.5)
docker compose from debian (2.26.1-4)
no static mac address or static ip address assignments in docker.
single host deployment / no docker swarm
containers are setup using multiple docker compose files; containers are
connected to eachother via
an external network definition.

I have not found a common method to reproduce this issue, but luckily I
did find the issue on a testing system so I am capturing some debug
logs that I can attach to this bug report later on.
I would be very curious to what the cause of the issue is and what would
be recommended to do to handle this issue
thanks again.
