我尝试过

• 我检查了 sources.list 文件，找不到警告中的条目
• 我还检查了 sources.list.d 目录，该目录是空的

sudo apt-get install --reinstall ca-certificates
sudo apt-get update --fix-missing

sudo mv sources.list.d/ sources.list.d.backup/
sudo mv sources.list sources.list.backup

sudo apt-get clean all

sudo apt-get update --fix-missing
sudo apt-get install --reinstall ca-certificates

我还想指出的是，大约两个月前，我将我的操作系统从 ubuntu 20.04 升级到了 22.04。
