如何在Alpine Linux 3.8上安装Chromium masked软件包？

我正在使用Vagrant和VirtualBox，并且正在运行 高山3.8 内：

$ vagrant up
Bringing machine 'default' up with 'virtualbox' provider...
==> default: Importing base box 'generic/alpine38'...
==> default: Matching MAC address for NAT networking...
==> default: Checking if box 'generic/alpine38' is up to date...
==> default: Setting the name of the VM: ep2018-workshop_default_1532787155941_48660
==> default: Clearing any previously set network interfaces...
==> default: Preparing network interfaces based on configuration...
    default: Adapter 1: nat
==> default: Forwarding ports...
    default: 22 (guest) => 2222 (host) (adapter 1)
==> default: Running 'pre-boot' VM customizations...
==> default: Booting VM...
==> default: Waiting for machine to boot. This may take a few minutes...
    default: SSH address: 127.0.0.1:2222
    default: SSH username: vagrant
    default: SSH auth method: private key
    default:
    default: Vagrant insecure key detected. Vagrant will automatically replace
    default: this with a newly generated keypair for better security.
    default:
    default: Inserting generated public key within guest...
    default: Removing insecure key from the guest if it's present...
    default: Key inserted! Disconnecting and reconnecting using new SSH key...
==> default: Machine booted and ready!

在尝试安装时 chromium，我收到有关社区存储库中屏蔽的缺失依赖项的错误消息：

$ vagrant ssh
localhost:~$ sudo apk add --update chromium

你知道如何解决这个问题吗？

apk add --update chromium@community

或删除 @community 来自 /etc/apk/repositories。官方社区回购固定是非常不寻常的配置。
