[EverlastingBugstopper]

Hi @rmarku - sorry that you've encountered this issue. This seems to be a problem with parsing your system's DNS resolv.conf configuration file. This panic occurs in an upstream dependency called resolv-conf. You might try inspecting that file and removing the offending entry. I'm going to close this issue as a duplicate of #1471.
