在 ubuntu 20.04 上安装 git 时发生错误

Question

当我尝试在 Ubuntu 20.04 上安装 git 时，出现错误。我使用了以下命令：

sudo apt-get install git

它产生了一个错误：

dpkg: warning: old mysql-server-8.0 package pre-removal script subprocess returned error exit status 1
dpkg: trying script from the new package instead ...
debconf: DbDriver "config": /var/cache/debconf/config.dat is locked by another process: Resource temporarily unavailable
dpkg: error processing archive /var/cache/apt/archives/mysql-server-8.0_8.0.27-0ubuntu0.20.04.1_amd64.deb (--unpack):
 new mysql-server-8.0 package pre-removal script subprocess returned error exit status 1
debconf: DbDriver "config": /var/cache/debconf/config.dat is locked by another process: Resource temporarily unavailable
dpkg: error while cleaning up:

Errors were encountered while processing:
 /var/cache/apt/archives/mysql-server-8.0_8.0.27-0ubuntu0.20.04.1_amd64.deb
E: Sub-process /usr/bin/dpkg returned an error code (1)

Answer 1

As shown here，表示 config.dat 文件被另一个进程使用，你需要杀死它。

sudo fuser -v -k /var/cache/debconf/config.dat

那会直接杀死所说的其他进程。

然后你可以再试一次你的安装命令。
