17.04 some icons are missing from system settings and cant disable touchpad

[caneraydinbey]

i opened gnome-control-center then disabled but it was not disabled. Also tried from command line.

Also when i open unity-control-center or system settimgs, i only see a few images. https://askubuntu.com/questions/925671/icons-in-system-settings-are-missing-ubuntu-server-17-04 like those


i already did those

udo apt-get install dconf-tools
DISPLAY=:0 dconf reset -f /org/compiz/
unity --reset-icons
setsid unity

but it only resetted my settings of ui. The icons did not come back.

also i have unity tweatk tool and when i open, i can see some settings there. Like power settings or icon size. so i hace those settimgs.

i am 17.04 . i installed ubuntu 17.04

and also when i click software update, it searcvhes for updates for seconds. then it says "failed to download repository information. please check your internet connecvtion".

and
when i click ok, it says no update is available. T his is my sourceslist
