解决办法:

自动安装存储库

wget -O - http://rpms.litespeedtech.com/debian/enable_lst_debian_repo.sh | bash

手动修复

grep -Ri litespeedtech /etc/apt/*

安装 GPG 密钥和源

wget -qO - https://rpms.litespeedtech.com/debian/lst_repo.gpg | sudo apt-key add -
sudo echo "deb http://rpms.litespeedtech.com/debian/ focal main" > /etc/apt/sources.list.d/openlitespeed.list

然后运行apt-get update,它应该消失了
