What is creating these bridges (as visible in the NetworkManager) upon start?

I have to delete them all every time in order for internet connectivity on a certain WiFi point to work, and as far as I see there are no adverse effects to removing them.

Using Ubuntu 18.04.

  • Quite possibly... and I haven't tried networking from a snap program, so I could be breaking it for them. – Vadim Peretokin May 27 at 11:50

    docker is creating these bridges. I have the same issue and the same workaround:-( – pLumo May 27 at 12:04

These bridges are being created by docker-compose. They run in a 172.x.x.x address space by default.

This can lead to issues with other networks having the same address space.

To get around this issue, edit docker-compose.yml and insert the following:

networks:
  default:
    ipam:
      driver: default
      config:
      -  subnet: 10.1.100.0/24

You might need to replace this subnet with one that does not conflict with your usual networks.

  • Would you know how to find out which docker-compose? I have no active containers running. – Vadim Peretokin May 29 at 18:26
