ネットワーク衝突してますエラー

借り物のVagrantfileで設定されていたBridged Network Address(config.vm.network "private_network", ip: "192.168.10.10")と自分のPCのネットワークが衝突していた。Vagrantfile側を192.168.20.10というように変えた。

The specified host network collides with a non-hostonly network!                                                                     

This will cause your specified IP to be inaccessible. Please change                                                                  

the IP or name of your host only network so that it no longer matches that of                                                        

a bridged or non-hostonly network.                                

Bridged Network Address: '192.168.10.0'                           

Host-only Network 'enp2s0': '192.168.10.0'   

Shared folderがないですよというエラー

借り物のVagrantfileで設定されていたのが合っていなかったのでその部分コメントアウト した。

 Vagrant was unable to mount VirtualBox shared folders. This is usually                                                               

because the filesystem "vboxsf" is not available. This filesystem is                                                                 

made available via the VirtualBox Guest Additions and kernel module.                                                                 

Please verify that these guest additions are properly installed in the                                                               

guest. This is not a bug in Vagrant and is usually caused by a faulty                                                                

Vagrant box. For context, the command attempted was:
