vagrant-cachier not working with DNF package manager of Fedora

[LalatenduMohanty]

While trying to use Fedora Vagrant boxes (https://atlas.hashicorp.com/fedora/) with libvirt provider

$ vagrant init fedora/23-cloud-base
$ vagrant up

I got below error because :

• The config file of DNF has changed from /etc/yum.conf to /etc/dnf/dnf.conf
• The cache directory is now at /var/cache/dnf
• The option to enable caching for DNF is sudo bash -c "echo 'keepcache=true' >> /etc/dnf/dnf.conf"

The following SSH command responded with a non-zero exit status.
Vagrant assumes that this means the command failed!

sed -i 's/keepcache=0/keepcache=1/g' /etc/yum.conf

Stdout from the command:



Stderr from the command:

sed: can't read /etc/yum.conf: No such file or directory

DNF is the default package manager for currently supported (from Fedora Project) Fedora releases i.e. Fedora 22 and 23 (21 's support is ending on Dec 4th 2015). However DNF is introduced from Fedora 18.

I hit this issue as well. I got around it with

$ vagrant ssh
$ sudo ln -s /etc/dnf/dnf.conf /etc/yum.conf 
$ exit
$ vagrant reload

Not the best, but appears to suffice.

As a workaround, I've tried the following that might be working (not fully sure, since I'm a newbee wrt dnf), in the Vagrantfile:

config.vm.provision "shell", inline: <<-SHELL
    sudo echo "keepcache=True" >> /etc/dnf/dnf.conf
    sudo rm -fr /var/cache/dnf
    sudo ln -s /tmp/vagrant-cache/dnf /var/cache/dnf
  SHELL

  if Vagrant.has_plugin?("vagrant-cachier")
    config.cache.scope = :box
    config.cache.auto_detect = false
  end

Missed this patch here. I wrote my own DNF plugin in #180. It also fixes the DNF/Yum problem by checking if DNF or Yum is installed on the machine.

Fixed in #180
