This is the recommended command-line upgrade method.<\/p>\n

About dnf upgrade<\/font><\/h2>\n
Aliases: up<\/font>
\nDeprecated aliases: update<\/font>, upgrade-to<\/font>, update-to<\/font>, localupdate<\/font>

Clean-up packages<\/h2>\n
You can safely remove packages no longer in use with:<\/p>\n
sudo dnf autoremove<\/code><\/pre>\n
 
\nYou can see duplicate packages (packages with multiple versions installed) with:<\/p>\n
sudo dnf repoquery --duplicates<\/code><\/pre>\n
 
\nSome packages that are still on your system may no longer be in the repositories. To see a list of these packages do:<\/p>\n
sudo dnf list extras<\/code><\/pre>\n
 
\nIf you see a package you do not need, or use, you can remove it with:<\/p>\n
sudo dnf remove package<\/code><\/pre>\n
 
\nOld kernels remain even after dnf autoremove<\/font>.
\n 
\nThe script below works whenever Fedora updates a kernel, and does not depend upon a system upgrade.<\/p>\n
#!\/usr\/bin\/env bash\n\nold_kernels=($(dnf repoquery --installonly --latest-limit=-1 -q))\nif [ "${#old_kernels[@]}" -eq 0 ]; then\n    echo "No old kernels found"\n    exit 0\nfi\n\nif ! dnf remove "${old_kernels[@]}"; then\n    echo "Failed to remove old kernels"\n    exit 1\nfi\n\necho "Removed old kernels"\nexit 0<\/code><\/pre>\n
Clean-up old symlinks<\/h2>\n
There may be some dangling symlinks in the filesystem after an upgrade. You can clean the dangling links by installing the symlinks utility and deleteing the old links.<\/p>\n
sudo dnf install symlinks<\/code><\/pre>\n
 
\nOnce the utility is installed you can audit for broken symlinks like shown below. -r means recursive.<\/p>\n
sudo symlinks -r \/usr | grep dangling<\/code><\/pre>\n
 
\nAfter you verify the list of broken symlinks you can delete them like shown below. -d means delete.<\/p>\n
sudo symlinks -r -d \/usr<\/code><\/pre>\n
