试图安装freerdp sudo apt-get install freerdp-x11
我搞错了
libfreerdp-codec1.1 :依赖: libjpeg8 (>= 8c),但它不能安装
我试着安装libjpeg8 sudo apt-get install libjpeg8-dev
E:'libjpeg8-dev‘包没有安装候选程序。

在Debian 9和更高版本中,经典的libjpeg8已经被libjpeg-turbo取代,它包括SIMD指令支持,以获得更好的性能(2-6x)和兼容的处理器。
项目主页:https://www.libjpeg-turbo.org/
因此,如果一个旧包请求libjpeg8,但它在Debian或任何与Debian相关的发行版中都不可用,您可以尝试安装libjpeg62-turbo (或更高版本)。虽然它最初是从遗留的libjpeg v6b代码库(解释版本号)中分叉出来的,但它也包括libjpeg v7和v8的ABI,因此应该是兼容的。
这不是很明显,所以我想把这个答案加到一个老问题上。

在Kali上,它被打包为freerdp2-x11名称。它可以通过以下方式安装:
sudo apt install freerdp2-x11或者sudo apt isntall freerdp2,freerdp2-x11将作为依赖项请参阅freerdp2 2安装。
但是,在安装包之前,您应该删除所有第三方存储库:
sudo rm /etc/apt/sources.list.d/*
echo "deb http://http.kali.org/kali kali-rolling main non-free contrib" | sudo tee /etc/apt/sources.list
sudo apt update && sudo apt upgrade发布于 2022-11-04 08:15:00
要安装libjpeg8-dev,请使用以下命令:
sudo apt install aptitude
sudo aptitude install libjpeg-dev然后,您可能需要选择“否”、“是”、“是”。请参阅我的详细说明:如何安装/升级到Poppler/的最新版本pdftoppm(撰写本文时版本22.11.0 )在Linux Ubuntu上
