Debian
當 apt-get dist-upgrade 什麼都不做時，如何安裝所有軟體包？
在我的 Debian 系統（Raspian Raspberry Pi）上，一些軟體包被保留了下來。我試過
sudo apt-get dist-upgrade了，但這並沒有導致升級。$ sudo apt-get upgrade -y Reading package lists... Done Building dependency tree Reading state information... Done Calculating upgrade...

$ dpkg --get-selections | grep hold是什麼導致這些軟體包受阻，我該如何升級它們？
根據 jordanm 的評論，它可能在測試儲存庫中缺少依賴項（基於 perl）。幾天后我再次嘗試，它似乎工作。
