Synaptic Package Manager

[ralphy]

Hold on please! The beauty in Linux comes also from its packaging structure.

First, let's figure few things out since we do not have any logs from your system:

1- Is your system up-to-date?
2- Can you open Menu => type software & and open Software and Updates? (I think that's what you are looking for)



3- If Software and Updates window opens, then it may just be a problem with your synaptic installation. Perhaps reinstalling Synaptic is all you need:

Code:

sudo apt remove --purge synaptic -y
sudo apt autoclean -y && sudo apt autoremove -y
sudo apt update && sudo apt upgrade -y && sudo apt install synaptic -y

If Software and Updates doesn't pop up then the issue may be related to it and not to Synaptic. You can test whether it launches from Terminal also:

Code:

software-properties-gtk
