i am running kubuntu 18.04 in virtualbox and currently working in a proxy environment. when i am trying to setup the proxy through
system settings ->network settings -> proxy .
then i see no changes and unable to browse. no system wide changes are observed ,ie proxy on system environment is not afftected after this . but as i am running
env variable is changes and able to use the internet connectivity.
please provide solution for this , to setup proxy system wide through setting ,not by export_proxy ( i don't want to unset the proxy each time as i shift to non-proxy environment.)
