Could someone help me, and my internet connection is good too but I can't update!

Answer 1

Do not update your Ubuntu operating system, Ubuntu updates cause huge problems. Linux does not require you to do so.

Upgrade you browser only.



When a new version of ubuntu comes out just backup your files and re install. I recomend reinstall of ubuntu every 4 years. If your present ubuntu works then "dont try to fix it".

Answer 2

edit your /etc/apt/sources.list file to remove or comment out all the references to cdrom devices.

Answer 3

Open up the terminal and sort sudo dpkg --configure -a it could not look such as you're typing on your password, yet you're. that's a secure practices characteristic so on lookers isn't waiting to work out the scale of your password.
