Debian - “警告：將安裝以下軟體包的不受信任版本！”
當我嘗試安裝或更新我得到的任何軟體包時：
Untrusted packages could compromise your system's security. You should only proceed with the installation if you are certain that this is what you want to do.我強烈懷疑這與我在更新時遇到的錯誤有關：

sudo aptitude reinstall debian-archive-keyring令人驚訝的是不會引起警告）。
請試試這個：
打開終端並執行以下命令：
sudo apt-get clean sudo rm -rf /var/lib/apt/lists/* sudo apt-get clean sudo apt-get update
閱讀APZ 的答案後，但想使用aptitude我成功執行了以下命令：
# clean the obsolete cache sudo aptitude clean # update the package information sudo aptitude update # install or upgrade the packages sudo aptitude install <list of packages to upgrade/install>該錯誤可能與過時的 apt 記憶體內容有關，但我得到的錯誤消息有點不同：
