apt - Yakketey Yak problem - Ask Ubuntu


i having problem yakketey yak. ubuntu user long time ago, 16.10 version new me. can me?

image 1 translation - repository informations download failed  image 2 translation -   e: obtaining failed cdrom://ubuntu 16.10 _yakkety yak_ - release amd64 (20161012.2)/dists/yakkety/main/binary-i386/packages  por favor utilize o apt-cdrom apt recognizes cd. apt-get update can't used add new cds e: obtaining failed http://ppa.launchpad.net/pinta-maintainers/pinta-stable/ubuntu/dists/yakkety/main/binary-amd64/packages  404  not found e: obtaining failed http://ppa.launchpad.net/pipelight/stable/ubuntu/dists/yakkety/main/binary-i386/packages  404  not found e: index files download failed. they're ignored or last ones replaced them.

if want console, it's pretty simple. need drop root shell , disable offending sources:

sudo add-apt-repository -r ppa:pinta-maintainers/pinta-stable sudo add-apt-repository -r ppa:pipelight/stable

finally, disable cd-rom source:

sudo nano /etc/apt/sources.list

find line begins deb:cdrom (should @ top) , place # @ beginning of line.

once you're done, reload apt cache:

sudo apt update

this problem happened because ubuntu looking non-existent software sources, unable find them, , therefore unable learn packages (or aren't in case). happens after installs.
