How to setup fastest mirror in Dnf

by

Dnf by default does not choose the fastest mirror, but this can be changed by editing the dnf.conf file.

The dnf.conf file is in /etc/dnf/dnf.conf.

Edit the file

sudo nano /etc/dnf/dnf.conf

Once the file opens the content should look something like this.

[main]
gpgcheck=1
installonly_limit=3
clean_requirements_on_remove=True
best=False
skip_if_unavailable=TrueCode language: PHP (php)

Let’s add fastmirror to the config and enable it.

Add below the line skip_if_unavaiable=True the following.

fastestmirror=1

The dnf.conf should look like this.

[main]
gpgcheck=1
installonly_limit=3
clean_requirements_on_remove=True
best=False
skip_if_unavailable=True
fastestmirror=1Code language: PHP (php)

Save the file.

Run the following command.

sudo dnf clean all

Now fastmirror is enabled you can download anything, for this example I will download Zeal an offline document browser.

sudo dnf install zeal

There is the output.
