I have tried to update all the packages in my ubuntu 14.04 system with the following commands:
- apt-get update
- apt-get install
- apt-get upgrade
It took some time, downloaded and completed the process. When I checked I could see that my system still uses the old versions (simply I checked the Firefox and Chrome versions). So I have checked the package updates through 'software updater' and it showed update is available. I was able to update to the latest versions after updating through it. So my doubt is why the commands didn't work without showing any errors and how come this GUI method worked?
