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
export_proxy http_proxy=http://'proxy:port'

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.)

  • Are you using Firefox ? It has its own proxy settings and ignore system-wide settings (as of writing). Mar 5 '19 at 11:00
  • @JohnChristopher yes I was using Firefox, but this issue also exists for chrome Mar 5 '19 at 14:37

can you precise the string format you use to setup proxy system wide trough system settings -> network settings -> proxy

http://proxy_host:port or proxy_host:port

i open a bug against firefox and ask a similar question to ubuntu:

i suppose (it works for me) if you type http://proxy_host:port it works for firefox (but not for evolution or pidgin)

IMHO it's wrong to say : FF has its own proxy settings and ignore system-wide settings and in my case : chrome uses proxy settings and i can browse with both values : http://proxy_host:port or proxy_host:port

  • thanks for solution, right now i have no access to the system to check this one, but yes your solution is right and one can set the proxy this way also. Sep 26 '19 at 6:58
