我最近在最新的 Ubuntu 版本上安装了 PeerGuardian，并收到以下错误消息：
不知道为什么会出现这个消息。我尝试在线搜索错误，但没有找到遇到同样问题的人。
更新：卸载并尝试重新安装 PeerGuardian 后，我收到以下错误消息：
pgld will soon be started ...
If any blocklists are missing, they will be downloaded. This may take several
minutes. Please be patient and don't abort. If you want to follow the update
process, then do in another terminal a
tail -f /var/log/pgl/pglcmd.log
The lists are saved to /var/spool/pgl/.
The installation of pglcmd will fail, if starting pgld fails. So if
downloading the blocklists fails temporarily, the installation will fail. In
this case you may turn the automatic starting off by setting in
/etc/pgl/pglcmd.conf:
INIT="0"
Then complete the installation and turn the automatic start on again:
sudo dpkg-reconfigure --force pglcmd
Please be patient ...

Package pglcmd is not configured yet.
