Due to some unknown error (supposedly after messing with update links), I was getting Temporary failure resolving 'packages.microsoft.com'
while using internet without proxy (no problem with proxy set up). So I came up with this solution, which I don't understand completely but it works like a charm. I am using Kubuntu-plasma.
In the solution of the link, it says:
If this fixes your temporary resolving messages then either wait for 24 hours to see if your ISP fixes the issue for you (or just contact your ISP) - or you can permanently add a DNS server to your system:
echo "nameserver 8.8.8.8" | sudo tee /etc/resolvconf/resolv.conf.d/base > /dev/null
to make the setting sustain after restart.
But on doing so, it says the file does not exist: tee: /etc/resolvconf/resolv.conf.d/base: No such file or directory
Do I need to create such file? Asking this before messing up with the system files to be on the safer side this time. I do not understand this very much and have no idea what to do? Would be very grateful if someone can help!
