php - Docker 镜像 : Unable to locate package php7. 2

Question

我有一个 bitbucket 管道设置，它已经完美地工作了一年，但几天前它停止工作了
这是我的 bitbucket 配置的开头

image: atlassian/default-image:2

options:
  max-time: 30
pipelines:
  default:
    - step:
        script:
          - echo "This script runs on all branches that don't have any specific pipeline assigned in 'branches'."
  branches:
    master:
      - step:
          caches:
            - composer
          name: cms
          deployment: production
          script:
            - apt-get update
            - apt-get install -y software-properties-common python-software-properties
            - add-apt-repository -y ppa:ondrej/php
            - apt-get update
            - apt-get install -y php7.2 php7.2-cli php7.2-common php7.2-mbstring
            - apt-get install -y php7.2-curl php7.2-xml
...
...

现在我不断收到以下错误(以前没有发生过):

+ apt-get install -y php7.2 php7.2-cli php7.2-common php7.2-mbstring
Reading package lists...
Building dependency tree...
Reading state information...
E: Unable to locate package php7.2

E: Couldn't find any package by regex 'php7.2-common'
E: Unable to locate package php7.2-mbstring
E: Couldn't find any package by regex 'php7.2-mbstring'

我在 docker 镜像端找不到任何更改，而且 ondrej 的 repo 似乎仍然包含这些包。可能是什么问题呢？

Answer 1

atlassian/default-image:2基于 ubuntu16.04(xenial)，但它的生命周期是 2021 年 4 月。
来自 ppa:ondrej/php我们接下来可以看到的主页:

Don't ask for end-of-life PHP versions or Ubuntu release, they won't be provided.

这意味着楼主已经取消了对ubuntu16.04的支持，这就是你无法在ubuntu16.04上安装php7.2的原因。
对于你，去 PPA 找到另一个 php7.2 ppa，例如 ppa:jason.grammenos.agility/php ，那么接下来可以解决您的问题:

$ add-apt-repository -y ppa:jason.grammenos.agility/php
$ apt-get update
$ apt-cache policy php7.2
php7.2:
  Installed: (none)
  Candidate: 7.2.15-1+ubuntu16.04.1+deb.sury.org+1
  Version table:
     7.2.15-1+ubuntu16.04.1+deb.sury.org+1 500
        500 http://ppa.launchpad.net/jason.grammenos.agility/php/ubuntu xenial/main amd64 Packages
$ apt-get install -y php7.2
