Learn how to update and upgrade your Linux kernel in Ubuntu.
What is difference between update and upgrade in Linux?
The update command only retrieves details about the most recent packages that are accessible on your system. No packages are downloaded or installed by it (just gets the package list). The actual download and update of the package to the new version is handled by the apt upgrade command.
Update the package list
sudo apt-get update
Get list of packages that will be upgraded (downloaded and installed)
apt list –upgradable
Don’t upgrade “libfwupd2” package
sudo apt-mark hold libfwupd2
Upgrade “libfwupd2” package
sudo apt-mark unhold libfwupd2
Upgrade packages
sudo apt-get upgrade
ls /var/lib/apt/lists/*
Run both update and upgrade package
sudo apt-get update && sudo apt-get upgrade -y
My favorite way to running update and upgrade (clean downloaded packages)
sudo apt-get update && sudo apt-get upgrade -y && rm -rf /var/lib/apt/lists/*
#linux #ubuntu #redhat #bash
