Debian 11环境下clamav-daemon启动后未生成/var/run/clamav/clamd.ctl套接字的问题求助

我在Debian 11上安装了clamav-daemon，但是启动之后发现它并没有创建配置里指定的LocalSocket /var/run/clamav/clamd.ctl，现在卡在这里了，想请教大家有没有解决思路。

先说说我的配置情况：/etc/clamav/clamd.conf里的LocalSocket配置是这样的：

LocalSocket /var/run/clamav/clamd.ctl

用systemctl status clamav-daemon.service查看服务状态，看起来一切都是正常运行的：

● clamav-daemon.service - Clam AntiVirus userspace daemon

Loaded: loaded (/lib/systemd/system/clamav-daemon.service; enabled; vendor preset: enabled)

但是当我查看socket状态的时候，却提示找不到这个单元：

systemctl status clamav-daemon.socket
Unit clamav-daemon.socket could not be found.

再看日志，/var/log/clamav/clamav.log里启动时的内容是这样的：

Fri Feb 17 15:55:19 2023 -> +++ Started at Fri Feb 17 15:55:19 2023

而/var/log/clamav/clamav-milter.log里因为找不到套接字，一直报警告：

Fri Feb 17 16:27:05 2023 -> WARNING: No clamd server appears to be

available Fri Feb 17 16:28:05 2023 -> WARNING: No clamd server appears

我检查过权限，/var/run/的属主是clamav用户、属组是root，而且运行clamd进程的确实也是clamav用户，执行ps aux | grep clamav的输出如下：

clamav       500  0.0  0.0  58248   704 ?        Ss   14:22   0:00

/usr/bin/freshclam -d --foreground=true clamav     31064  0.0  0.0

我已经尝试过这些方法，但都没用：
