I guess what you mean by “sudo update” is “sudo apt-get update”. When you use “sudo apt-get update”, it will not actually install new versions of applications or software. “apt-get update” downloads the lists of packages from the repositories and then updates them to retrieve the information on the latest versions of packages including their dependencies.
It re-syncs the package index files from their sources. The indexes of the available packages are obtained from the location indicated in “/etc/apt/sources.list(5)”. If you want to upgrade, it is always necessary to do an update first using “apt-get update”. Once your package lists have been updated, you can now do an upgrade.
To upgrade, use “apt-get upgrade”. It will retrieve new versions of all the packages that exist on the computer.
