Ubuntu mate not upgrading

Hi, the upgrade manager tell me there are some upgrades to do but when i press on “install now” it will tell me that there is no Internet connection please help.

Open a terminal and enter:

sudo apt update

Get any errors? If no errors, run:

sudo apt full-upgrade

Thanks now all the software are updated!
A little question
I will need to run that command any time i want to upgrade?

If the GUI doesn’t work yes. I recommended you to run the following:

sudo apt update && sudo apt full-upgrade && sudo apt autoremove && sudo apt autoclean

You must know that those are 4 consecutive commands without the need to enter then after finishing the others but if any of them give you errors the next ones won’t be executed.

Thanks i Will make an .sh to do that for me!

Update-Manager was probably hung up and should now work normally. Though there is nothing wrong with doing it in terminal like @malwaredpc has posted.

I prefer Synaptic Package Manager over UpdateManager and have disabled it.

Yes. Also disabling UM will make the system to boot up faster.
