Vagrant up ignorando provisionamento do mysql

Boa tarde,

estou tentando subir uma VM conforme a aula 4, entretanto não está sendo possível pois o mysql não é instalado.

Meu código:

$script_mysql = <<-SCRIPT
    apt-get update && \
    apt-get install -y mysql-server-5.7 && \
    mysql -e "create user 'phpuser'@'%' identified by 'pass';"
SCRIPT

Vagrant.configure("2") do |config|
    config.vm.box = "ubuntu/bionic64"
    config.vm.network "forwarded_port", guest: 80, host: 8087
    config.vm.network "public_network"

    config.vm.provision "shell", 
        inline: "cat / configs/id_bionic.pub >> .ssh/authorized_keys"

    config.vm.provision "shell", inline: $script_mysql

    config.vm.synced_folder "./configs/", "/configs"
    config.vm.synced_folder ".", "/vagrant", disable:true
end

Alternativamente tentei assim:

Vagrant.configure("2") do |config|

    config.vm.box = "ubuntu/bionic64"
    config.vm.network "forwarded_port", guest: 80, host: 8087
    config.vm.network "public_network"

    config.vm.provision "shell", 
        inline: "cat / configs/id_bionic.pub >> .ssh/authorized_keys"

    config.vm.provision "shell", inline: "apt-get update"
    config.vm.provision "shell", inline: "apt-get install -y mysql-server-5.7"
    config.vm.provision "shell", inline: "mysql -e create user 'phpuser'@'%' identified by 'pass';"

    config.vm.synced_folder "./configs/", "/configs"
    config.vm.synced_folder ".", "/vagrant", disable:true
end

O log que recebo é o seguinte:

The SSH command responded with a non-zero exit status. Vagrant
assumes that this means the command failed. The output for this command
should be in the log above. Please read the output to determine what
went wrong.

Onde estou errando?
