In Ubuntu 16.04, I tried to open the software & updates
. But didn't open. If I click to software & updates icon,It will show on launcher pad and blinking around 15sec. And automatically closing.
The instructions offered were GREAT! But, it took a while to understand EXACTLY The suggested steps. Therefore, I'm restating them for newbees like me.
- Open the terminal using Ctrl + Alt + t.
- type
sudo apt update
and press Enter. - type
sudo apt upgrade
and press Enter. - you will answer the question by typing or selecting
Y
and press Enter. - now, please wait a long time while a process goes on. A bar shows slow progress up to 100%.
- restart the computer.
The results were GREAT. It solved my Ubuntu software problem, the SW update problem, continuous "system error" messages, AND a failed network that I had painfully constructed. Remember, I'm a NEWBEE and wish I knew more about Unix.
Ctrl + Alt + t
then typesudo apt update && sudo apt upgrade -y
and pressEnter
after that try to open it and see if it stays opensoftware-properties-gtk
in the Terminal and press Enter. This will probably also fail to open Software & Updates but the output may be helpful. Select all text in the Terminal from the beginning of the line on which you typed the first command to the end of the output fromsoftware-properties-gtk
, copy it to the clipboard, and edit your question to add it.
