Package: network-manager Version: 1.14.6-2+deb10u1 NetworkManager removes manually added addresses from interfaces. E.g. if I attach a USB ethernet dongle and run "ip a a 192.0.2.1/24 dev eth0", some time later (it varies. A minute… sometimes an hour) the NetworkManager deletes that address, aborting my huge file transfer mid way.
I have verified with netlink that it's indeed the NetworkManager process that removes the address.
