How to System Upgrades with DNF

System Upgrades with DNF

Upgrade to Fedora 23 with the native package manager dnf. The updates are performed in an offline environment that allows system packages to be safely replaced.

Upgrading with DNF

  1. This upgrade functionality comes from a dnf plugin. Install the package:
    # dnf install dnf-plugin-system-upgrade
  2. Update your system.
    # dnf update
  3. Some third party repos may not be available for the next version of Fedora. Check the status of your configured repositories:
    #dnf repolist –releasever 23If problems are reported with a repository, you may wish to disable it:
    # dnf config-manager –set-disabled repo-name
  4. Prepare the upgrade enviroment.
    #dnf system-upgrade download –releasever 23
  5. Reboot to perform the upgrade.
    # dnf system-upgrade reboot
  6. If an upgrade fails, clean up the download, resolve any issues, and try again.
    # dnf system-upgrade clean

Syncing package versions

By default, if a package is a newer version than the same package in the target Fedora release, it will not be replaced. Some common post-installation issues involving packages from mixed repositories can be resolved by performing a distribution synchronization, or distro-sync, which ensures that packages are replaced with those in the target repos, wherever possible.

You can perform this operation during the system upgrade with the –distro-sync.

How to set SELinux Domain in Permissive mode

When SELinux is running in permissive mode, SELinux does not deny access, but denials are logged for actions that would have been denied if running in enforcing mode. Permissive domains allow an administrator to configure a single process (domain) to run permissive, rather than making the whole system permissive. SELinux checks are still performed for permissive domains; however, the kernel allows access and reports an AVC denial for situations where SELinux would have denied access.

Making a Domain Permissive:

semanage permissive -a virt_t

View a list of domains you have made permissive:

semodule -l | grep permissive

Disabling Permissive Domain:

semanage permissive -d virt_t

Disabling All Permissive Domains:

semodule -d permissivedomains
