Linux ubuntu apt get install all fiald？rsyslog出现一些错误

这就是我遇到的错误。 首先，我只想重新安装mysql。 当我重新启动mysql服务时， ubuntu给我一个

unkonw实例

错误。

所以，我重新安装它，然后，我不能再安装它。似乎apt get安装未工作。

首先停止rsyslog

The user `syslog' is already a member of `adm'.

然后尝试：

 sudo service rsyslog stop
 sudo systemctl stop rsyslog.service
 sudo systemctl disable rsyslog.service

尝试运行

sudo-apt-get-clean和sudo-apt-get-update

，然后安装软件包。它将清除并重建现有列表。

sudo-apt-get-clean和sudo-apt-get-update

此cammond不返回任何内容。。您可以检查

/var/log/apt/term.log

apt日志文件。日志文件可以帮助您解决问题。此外，如果存在某些依赖项问题，请先运行此命令

apt get install-f

。

 sudo apt-get -f install
