我有 Ubuntu 21.04。它附带 SNAP。似乎已经落后了，以及 flatpak 上的工作原理。
我安装了某个版本的 Handbrake，但可能比较旧，所以我想更新它。我查看了 SNAP，它没有显示已安装，我更愿意直接更新，以防 SNAP 跟不上最新版本。
因此我深入研究了“如何安装 flatpak”。
看这里： https://flatpak.org/setup/Ubuntu
然后：
sudo add-apt-repository ppa:flatpak/stable
sudo apt update
sudo apt install flatpak
但是我在执行此操作时发现了错误。
全部 3 个命令。
但错误马上就开始了。
me@me-desktop:~/Downloads$ sudo add-apt-repository ppa:flatpak/stable
Repository: 'deb http://ppa.launchpad.net/flatpak/stable/ubuntu/ hirsute main'

所以这是行不通的。
