PHP 更新损坏

我在 Ubuntu 服务器 20.04 上，使用 php7.4-fpm 运行 LAMP。

我刚刚执行了最新的更新/升级并确认一切正常：

● php7.4-fpm.service - The PHP 7.4 FastCGI Process Manager
     Loaded: loaded (/lib/systemd/system/php7.4-fpm.service; enabled; vendor preset: enabled)
     Active: active (running) since Fri 2022-08-26 00:50:45 CST; 7min ago
       Docs: man:php-fpm7.4(8)
   Main PID: 120871 (php-fpm7.4)
     Status: "Processes active: 0, idle: 2, Requests: 24, slow: 0, Traffic: 0.1req/sec"
      Tasks: 3 (limit: 4380)
     Memory: 80.8M
     CGroup: /system.slice/php7.4-fpm.service
             ├─120871 php-fpm: master process (/etc/php/7.4/fpm/php-fpm.conf)
             ├─120892 php-fpm: pool www
             └─120893 php-fpm: pool www

然后几分钟后......我的 Nextcloud 安装突然停止同步，所以我重新检查 php-fpm 的状态，我得到：

● php7.4-fpm.service
     Loaded: masked (Reason: Unit php7.4-fpm.service is masked.)
     Active: inactive (dead) since Fri 2022-08-26 01:07:14 CST; 5min ago
   Main PID: 120871 (code=exited, status=0/SUCCESS)
     Status: "Processes active: 0, idle: 2, Requests: 44, slow: 0, Traffic: 0req/sec"

Aug 26 01:07:14 admin.example.com systemd[1]: Stopped The PHP 7.4 FastCGI Process Manager.
Warning: journal has been rotated since unit was started, output may be incomplete.`

而且，毫不夸张地说，/lib/systemd/system/php7.4-fpm.service不再存在

# stat /lib/systemd/system/php7.4-fpm.service
stat: cannot stat '/lib/systemd/system/php7.4-fpm.service': No such file or directory

我检查了syslog根据时间戳屏蔽服务时发生的情况...日志中根本没有任何内容可以解释发生的情况：

Aug 26 01:07:14 admin systemd[1]: Stopped The PHP 7.4 FastCGI Process Manager.
Aug 26 01:07:14 admin systemd[1]: php7.4-fpm.service: Succeeded.

我尝试解决这个问题的事情：

当我尝试使用 解密 php7.4-fpm 时systemctl unmask php7.4-fpm，会发生两件事：

  1. /etc/systemd/system/php7.4-fpm.service已移除。/etc/systemd/system/php7.4-fpm.service是 /dev/null 的符号链接

  2. php7.4-fpm.service 启动使用init.d

● php7.4-fpm.service - LSB: starts php7.4-fpm
     Loaded: loaded (/etc/init.d/php7.4-fpm; generated)
     Active: active (exited) since Fri 2022-08-26 09:09:10 CST; 6min ago
       Docs: man:systemd-sysv-generator(8)
      Tasks: 0 (limit: 4380)
     Memory: 0B
     CGroup: /system.slice/php7.4-fpm.service

如果我尝试使用重新安装 php7.4fpmapt-get install --reinstall php7.4-fpm我得到：

root@admin:~# apt-get install --reinstall php7.4-fpm

Some packages could not be installed. This may mean that you have

distribution that some required packages have not yet been created

The following information may help to resolve the situation:

The following packages have unmet dependencies:
 php7.4-fpm : Depends: php7.4-common (= 7.4.3-4ubuntu2.12) but 7.4.3-4ubuntu2.13 is to be installed
E: Unable to correct problems, you have held broken packages.

以上所有步骤均基于这篇文章： https://askubuntu.com/questions/804946/systemctl-how-to-unmask

我目前被破损的包裹困住了

是的，我已经尝试过：
apt install -f
dpkg --configure -a

没有任何帮助..有人知道如何重新安装 PHP 吗？

答案1

这个问题从根本上来说似乎是上游 ubuntu 存储库的打包问题，维护者可能需要一些时间来解决。

The following packages have unmet dependencies:
 php7.4-fpm : Depends: php7.4-common (= 7.4.3-4ubuntu2.12) but 7.4.3-4ubuntu2.13 is to be installed
E: Unable to correct problems, you have held broken packages.

与此同时，解决这个问题的唯一方法似乎是-前-您执行最新的 php 更新...确保您的计算机上安装了此存储库：

sudo add-apt-repository ppa:ondrej/php

如果在更新之前安装此存储库，您可以避免上面的噩梦。
