我正在嘗試在Docker ubuntu：trusty容器中安裝supervisor。這是一個小例子Dockerfile演示我的問題：當我嘗試建立從這個Dockerfile圖像無法在Docker容器上安裝Supervisor ubuntu：trusty

# Get supervisor:
RUN apt-get update && apt-get install -y supervisor

Package supervisor 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 'supervisor' has no installation candidate
The command '/bin/sh -c apt-get update && apt-get install -y supervisor' returned a non-zero code: 100
輸出不同可能是由於Docker的緩存功能。
我以爲在Docker容器上安裝的東西應該可以在Ubuntu中使用：trusty。我在這裏錯過了什麼？
你有沒有嘗試https://github.com/edgester/docker-gerrit/blob/master/Dockerfile＃L15-L19？ – VonC
@VonC：謝謝你的回覆。我嘗試過，但我仍然得到某種身份驗證錯誤。這是我得到的錯誤行：W：GPG錯誤：http://archive.ubuntu.com trusty發佈：由於公鑰不可用，因此無法驗證以下簽名：NO_PUBKEY 16126D3A3E5C1192。我想知道問題出在我的機器上，而不是容器本身。 – real
如果我將第一行更改爲「FROM ubuntu：wily」（Ubuntu 15.10），則一切正常。我希望與ubuntu 14.04一起工作，因爲它是一個長期的支持版本，但如果我沒有選擇，它就是這樣。 – real
