sudo freshclam 不工作：错误：无法在追加模式下打开 /var/log/clamav/freshclam.log（检查权限！）

Question

如果我/etc/clamav/freshclam.conf像这样注释掉 UpdateLogFile 行...

\#UpdateLogFile /var/log/clamav/freshclam.log

...然后我可以运行 sudo freshclam 没问题：

/etc/clamav$ sudo freshclam ClamAV update process started at Mon Feb 
6 00:17:07 2017 main.cvd is up to date (version: 57, sigs: 4218790,
f-level: 60, builder: amishhammer) daily.cld is up to date (version:
23009, sigs: 1509149, f-level: 63, builder: neo) bytecode.cld is up to
date (version: 290, sigs: 55, f-level: 63, builder: neo)

但是，如果我取消注释 freshclam.conf 中的 UpdateLogFile 行并运行 sudo freshclam，我会得到：

/etc/clamav$ sudo freshclam 
ERROR: Can't open /var/log/clamav/freshclam.log in append mode (check permissions!).
ERROR: Problem with internal logger (UpdateLogFile = /var/log/clamav/freshclam.log).

以下是权限/var/log：

drwxrwxrwx  1 root root     9 Feb  3  2016 log

以下是权限/var/log/clamav：

drwxr-xr-x  2 clamav    clamav    4096 Feb  5 22:18 clamav

以下是权限/var/log/clamav/freshclam.log：

-rw-r-----  1 clamav adm       0 Feb  5 22:18 freshclam.log

我花了一整天的时间尝试各种论坛中提到的解决方案，但没有运气。

这是我正在运行的 Ubuntu 服务器版本：

Description:    Ubuntu 14.04.5 LTS

和 clamav 的引擎版本：

Engine version: 0.99.2

有人可以帮助我吗？

停止 clamav-daemon 没有帮助：

/var/log$ sudo /etc/init.d/clamav-daemon stop 

* Stopping ClamAV daemon clamd        
[ OK ]  /var/log$ sudo freshclam
ERROR: Can't open /var/log/clamav/freshclam.log in append mode (check
permissions!). ERROR: Problem with internal logger (UpdateLogFile =
/var/log/clamav/freshclam.log).

的输出sudo lsof | grep clam是什么：

/var/log$ sudo lsof | grep clam
/var/log$

似乎什么都没有锁定 /var/log/clamav/freshclam.log

这是 的输出sudo service --status-all | grep clamav，不包括带有问号且与 clamav 无关的行：

$ sudo service --status-all | grep clamav 
[ - ] clamav-daemon
[ - ] clamav-freshclam
$

Can't open /var/log/clamav/freshclam.log in append mode (check permissions!)当我尝试运行 clamav-daemon 时出现同样的错误：

$ sudo service clamav-daemon start
 * Starting ClamAV daemon clamd
ERROR: Can't open /var/log/clamav/clamav.log in append mode (check permissions!).
ERROR: Can't initialize the internal logger
$

更新：清除并重新安装clamav，clamav-freshclam并clamav-daemon没有解决问题。我仍然收到相同的错误：

$ sudo freshclam
ERROR: Can't open /var/log/clamav/freshclam.log in append mode (check permissions!).
ERROR: Problem with internal logger (UpdateLogFile = /var/log/clamav/freshclam.log).
$

更新2：我做了一个sudo reboot，停止了clamav-freshclam，确保sudo lsof | grep clam没有返回任何东西，并且输出sudo service --status-all | grep clamav仍然只有减号clamav和旁边的符号clamav-daemon。冉sudo freshclam再次，和相同的错误如上述（再次）。

sudo freshclam 命令用于更新您的防病毒数据库，当另一个实例（自动更新）正在运行时无法运行该数据库。

停止自动更新过程： sudo /etc/init.d/clamav-freshclam stop

运行手动更新： sudo freshclam

重新启动自动更新过程： sudo /etc/init.d/clamav-freshclam start
