Package: docker.io
Version: 20.10.5+dfsg1-1+deb11u2
Severity: important
Dear Maintainer,
Installing docker.io rendered my server inoperable. Solely as a result of
"apt-get install docker.io", it installed iptables rules which corrupted
the network configuration rendering the network unusable.
Stopping docker with "systemctl docker stop" did not restore the network
state to operability.
Uninstalling docker with "dpkg --purge docker.io" did not restore the
network state to operability.
Manually removing the iptables rules docker installed did not restore the
network state to operability.
It was a server running lots of vms, so it was a pain to reboot -- the
solution which finally restored the network function.
The problem was successfully worked around by adding a line to
/etc/default/docker:
DOCKER_OPTS=--iptables=false
Merely installing a software package SHOULD NOT render the network unusable.
Suggested correction:
Either add iptables=false as default, or do not immediately start docker
upon installation so that merely installing docker does not change the
network configuration on the machine.
