How to remove proxy in Ubuntu 18.04 terminal?

How do I remove proxy settings from terminal?

hansm: you should not change host name.

that is what causes issues when network changes dtosms: what makes you think you need to? I would just reboot. I tried setting it to eth0, didn't help, then eth1, no difference. dtosms: you don't "need to". hansm: are you sure there is an IP on your router? is your subnet mask is for a /24? tomreyn thanks! That will do the trick. hansm: you probably just set your system to use the (newly configured) proxy by default rather than the old one. You could have set gsettings: org.gnome.SettingsDaemon disable-dns to 0
dtosms: you're welcome, though a reboot should solve other issues as well, too. I do believe I already rebooted the box and my other VM's are all up again. Let me try rebooting this machine what is the diffrence between sudo apt upgrade and upgrade

s10gopal: the difference is apt upgrades/installs all needed updates. Update only updates the packages list.
k1l, I'm not sure about the IP, but yes, I'm using a CIDR of a /24. k1l, here's an output from ifconfig -a. ok so, sudo apt update && sudo apt upgrade && sudo apt dist-upgrade is same

hansm: well, its an address on ips 1:23 but doesnt mean it gets ip 192.168.42.0
I dont understand ?
