解决方案

您可以手动安装 gpg 密钥：

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys D51DB14E9FFECCF3

您还需要编辑thopiekar-ubuntu-sierrabreeze-focal.list文件。

sudo nano /etc/apt/sources.list.d/thopiekar-ubuntu-sierrabreeze-focal.list

更改focal为bionic：

deb http://ppa.launchpad.net/thopiekar/sierrabreeze/ubuntu bionic main

运行：

sudo apt update
sudo apt install sierrabreeze
