我嘗試使用此處的 ubuntu 安裝程式腳本安裝網頁測試代理https://github.com/WPO-Foundation/wptagent-install
在新的 Azure Ubuntu 18.04 LTS 映像上，它可以正常運作。
但是，我需要將其安裝在新的 VPSCity Ubuntu 18.04 LTS 映像（位於紐西蘭）上。當在此運行安裝程式時，它會失敗並顯示：
$ sudo apt-get install ttf-mscorefonts-installer
Reading package lists... Done
Building dependency tree
Reading state information... Done
Package ttf-mscorefonts-installer is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
E: Package 'ttf-mscorefonts-installer' has no installation candidate
在此之前我已經做了以下工作：
sudo apt-get update
sudo apt-get upgrade -y
貓 /etc/apt/sources.list
給出
deb http://archive.ubuntu.com/ubuntu bionic main restricted universe
deb http://archive.ubuntu.com/ubuntu bionic-updates main restricted universe
deb http://security.ubuntu.com/ubuntu bionic-security main restricted universe multiverse
deb http://archive.canonical.com/ubuntu bionic partner
我看到一些帖子說我需要啟用多元宇宙。如何透過 SSH 命令列會話執行此操作？
兩個不同的 Ubuntu 18.04 LTS 伺服器差異如此之大，這正常嗎？
我也在20.04上嘗試過，同樣的問題。
答案1
如果您在以下位置搜尋該包軟體包.ubuntu.com你會注意到包裹在多重宇宙 儲存庫，您的sources.list中缺少它。
您只需將其新增至您的sources.list 檔案中的行：
deb http://archive.ubuntu.com/ubuntu bionic main restricted universe multiverse
deb http://archive.ubuntu.com/ubuntu bionic-updates main restricted universe multiverse

我找到了解決方案。
我從 Azure 虛擬機器中取得了正在工作的sources.list，並將其新增至現有虛擬機器的末尾，因此我更新後的sources.list 如下：

deb http://archive.ubuntu.com/ubuntu bionic-updates main restricted universe
deb http://security.ubuntu.com/ubuntu bionic-security main restricted universe multiverse
deb http://archive.canonical.com/ubuntu bionic partner

deb http://azure.archive.ubuntu.com/ubuntu/ bionic-updates main restricted
deb http://azure.archive.ubuntu.com/ubuntu/ bionic universe
deb http://azure.archive.ubuntu.com/ubuntu/ bionic-updates universe
