Comment 37 for bug 1754671

dwmw2, the systemd fix was mainly meant for people with standard configuration where this fix is actually needed and solve the problem.

You are writing that adding "dns-priority=-1;dns-search=~." solves the problem for you. Where/to which file did you add this? Do you need this already with the original network-manager version of Bionic (1.10.6) or do you only need ot after the update (1.10.14)?
