我跟着itsfoss 上的指南在我的 dell optiplex 9020 上安装 mesa。原因是我想在 Jellyfin 中使用硬件加速，这显然需要 mesa。
我使用添加了 kisak reposudo add-apt-repository ppa:kisak/kisak-mesa
然后我使用sudo apt update
但是，当我使用sudo apt install mesa（如指南所建议的那样）时，我只收到一条unable to locate package mesa消息。
似乎已启用使用apt policykisak repo。我还启用了 multiverse、main、restricted 和 universe 存储库。
使用glxinfo | grep Mesa; lscpi -k; lspci -k | grep -Ei "video|vga|3d" -A2; apt-cache policy mesa-utils; dpkg -l | grep -i mesa给了我这个输出：

我只在通过 ssh 登录时看到命令。尝试在正常登录后在终端窗口中使用该
Error: unable to open display命令glxinfo您无法安装，
mesa因为没有名为该名称的包。您正在使用的“指南”无法按书面形式工作，因为没有名为的包
mesa。当您将其中一个 ppa 添加到系统时，系统上和 ppa 中存在的所有软件包都将被 ppa 版本替换。要实现这一点，请在添加 ppa 后
sudo apt update执行以下命令sudo apt upgrade。您不必专门安装软件包即可实现这一点。这是使用 ppa 的风险之一。我将
kisakppa 添加到运行 mesa 的虚拟机中。--
在添加它之前，glxinfo | grep Mesa报告OpenGL version string: 3.1 Mesa 21.0.1--添加它并执行更新和升级后，相同的命令报告
OpenGL version string: 3.1 Mesa 21.1.1 - kisak-mesa PPA我没有执行任何sudo apt install mesa命令。——以下软件包已更新和/或添加。
简而言之，您不需要“安装 mesa”即可从该 ppa 获取 Mesa 的升级版本。添加 ppa，执行更新和升级即可。
