The more I dig into the problem, the more I think that these 2 issues are related. However, they are very likely my fault, therefore sorry for making a fuss. Two questions remain for me: 1) Is this AppArmor error actually a bug or something that is specific to my system as well? I'm not sure, but I don't mind if we assume that it is specific to my system. 2) Am I missing a dependency for domain name resolution? Is there a package that dnsmasq can functionally replace? If yes, should it be a dependency for other packages that connect to the internet?
