答案1

我会做什么：

$ sudo -s
# junk=$(grep -l opensuse /etc/apt/source.list /etc/apt/source.list.d/*)
# mv "$junk" "${junk}.bak"
# apt update
# apt upgrade

答案2

正如其他人提到的，一个 openSUSE 存储库不存在。但这仅适用于http://download.opensuse.org/repositories/home:/strycore/Debian第二个存储库：http://download.opensuse.org/repositories/home:/strycore/

因此，您可能需要检查并修复列表文件/etc/apt/source.list，并/etc/apt/source.list.d/*.list更加小心，而不是遵循建议的锤击方法 ;)。此 repo 是否对您有用是另一个问题。

但还有另一个问题：

Err:3 http://deb.debian.org/debian-security buster/updates InRelease                                               
  The following signatures couldn't be verified because the public key is not available: NO_PUBKEY AA8E81B4331F7F50 NO_PUBKEY 112695A0E562B32A

这可能意味着您没有将公共 Debian 存储库密钥/密钥环添加到您信任的存储库密钥中。最简单的方法可能是手动安装/更新官方密钥环包：

cd /tmp
wget https://deb.debian.org/debian/pool/main/d/debian-archive-keyring/debian-archive-keyring_2019.1_all.deb
dpkg -i debian-archive-keyring_2019.1_all.deb
rm debian-archive-keyring_2019.1_all.deb

这是存储库本身的一部分，因此在应用时将保持最新apt-get upgrade。对于未来的读者，如果上述软件包不再存在，或者您使用不同的 Debian 版本，请查看以下内容以了解适合您的 Debian 版本的当前密钥环包：https://packages.debian.org/debian-archive-keyring
