I was installing redis and came across php8.3-fpm installation error. This are the relevant installation messages:

needrestart is being skipped since dpkg has failed
E: Sub-process /usr/bin/dpkg returned an error code (1)
Systemctl and yournalctl messages are not particularly descriptive - just saying php8.3-fpm failed to start with result 'timeout'.
The error seem to be with dpkg processing php8.3-fpm : installed php8.3-fpm package post-installation script subprocess returned error exit status 1

exit 0
Not familiar with how dpkg functions, but exit 1 occurs in 2 locations. First one occurs when reading apache conf files. I have removed apache2 so this one cannot not trigger anymore. The second one just signals that start/restart failed.
Any tips on what could be the problem? This seems to be above my skill level.

Additionaly, manually starting the service with /usr/sbin/php-fpm8.3 --nodaemonize --fpm-config /etc/php/8.3/fpm/php-fpm.conf returns
NOTICE: fpm is running, pid 334206
NOTICE: ready to handle connections

... no more messages
indicating that fpm was started successfully, but perhaps systemd has an issue? Am I dealing with mismatched PID numbers?
