在Debian buster/sid中找不到libmysql++-dev包。

Question

我试图在我的Debian服务器上安装libmysql++-dev，但是我得到了下面的错误“无法找到包”。

root@rs-dal-karthik-test:~# apt-cache search libmysql++-dev
root@rs-dal-karthik-test:~# apt-get install libmysql++-dev
Reading package lists... Done
Building dependency tree       
Reading state information... Done
E: Unable to locate package libmysql++-dev
E: Couldn't find any package by regex 'libmysql++-dev'

我更新了我的/etc/apt/sources.list如下：

root@rs-dal-karthik-test:~# cat /etc/apt/sources.list
deb http://mirror.rackspace.com/debian buster main contrib non-free
deb-src http://mirror.rackspace.com/debian buster main contrib non-free

deb http://mirror.rackspace.com/debian-security/ buster/updates main contrib non-free
deb-src http://mirror.rackspace.com/debian-security/ buster/updates main contrib non-free
root@rs-dal-karthik-test:~# 

在更新了apt-get upgrade文件之后，我运行了sources.list，但是似乎没有什么效果。

官方的Debian /sid链接有包信息https://packages.debian.org/sid/libmysql++-dev。

以下是操作系统的详细信息：

root@rs-dal-karthik-test:~# cat /etc/os-release 
PRETTY_NAME="Debian GNU/Linux buster/sid"
NAME="Debian GNU/Linux"
ID=debian
HOME_URL="https://www.debian.org/"
SUPPORT_URL="https://www.debian.org/support"
BUG_REPORT_URL="https://bugs.debian.org/"
root@rs-dal-karthik-test:~# 

我不知道如何在我的服务器上安装这个软件包。

如下面的注释所述，在修改sources.list后更新输出集

您的存储库只引用Buster，而且mysql++包集不是Buster的一部分，因为打包是错误的(参见#871302和#919377)。

测试用户的最佳实践建议同时配置测试(Buster当前)和不稳定存储库，以便在不进行测试时可以从不稳定的包中安装包。这确实创造了安装be软件的可能性，就像这里的情况一样。

我不建议在服务器上运行测试，尤其是现在--为了准备Debian的下一个版本，测试被冻结了，所以更新(包括安全修复)可能需要比通常更长的时间才能在那里获得。
