깨진 PHP 업데이트

저는 php7.4-fpm을 사용하여 Ubuntu 서버 20.04에서 LAMP를 실행하고 있습니다.

방금 최신 업데이트/업그레이드를 수행했고 모든 것이 제대로 작동하는지 확인했습니다.

● 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"

     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

그리고 몇 분 후... Nextcloud 설치가 갑자기 동기화를 중단하여 php-fpm 상태를 다시 확인했고 다음과 같은 결과를 얻었습니다.

● php7.4-fpm.service
     Loaded: masked (Reason: Unit php7.4-fpm.service is masked.)

그리고 말 그대로 /lib/systemd/system/php7.4-fpm.service더 이상 존재하지 않습니다.

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

타임스탬프를 기준으로 서비스를 차단하면 어떤 일이 발생하는지 확인했습니다 syslog. 로그에는 무슨 일이 일어나고 있는지 설명할 내용이 없습니다.

이 문제를 해결하기 위해 시도한 것:

php7.4-fpm을 사용하여 암호를 해독하려고 하면 systemctl unmask php7.4-fpm두 가지 일이 발생합니다.

1. /etc/systemd/system/php7.4-fpm.service제거됨. /etc/systemd/system/php7.4-fpm.service/dev/null에 대한 심볼릭 링크입니다.

2. php7.4-fpm.service가 사용되기 시작합니다.init.d

apt-get install --reinstall php7.4-fpm다음을 사용하여 php7.4fpm을 다시 설치하려고 하면

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

위의 모든 단계는 다음 문서를 기반으로 합니다. https://askubuntu.com/questions/804946/systemctl-how-to-unmask

현재 손상된 패키지로 인해 갇혀 있습니다.

예, 시도해 보았습니다.
apt install -f
dpkg --configure -a

도움이 되지 않습니다. PHP를 다시 설치하는 방법을 아는 사람이 있습니까?
