以下是我在 Ubuntu 20.04 上作为管道任务运行的 shell 脚本。
echo "line1"
sudo apt-get update
echo "line2"
sudo apt install snapd
echo "line3"
#sudo apt-get install -y xpdf
sudo snap install okular
echo "line4"
sudo apt install mailutils
echo "line5"
sudo apt install mutt
但是，我遇到了失败，并且 mailutils 和 mutt 没有安装。我无法找到到底出了什么问题。
有人可以帮忙吗。
以下是日志。

答案1
根据您的日志，mailutils并且mutt安装正确，但是您的管道将标准错误的任何输出视为错误，并apt在那里写入警告：
警告：apt 没有稳定的 CLI 界面。在脚本中谨慎使用。
为了避免出现问题，请改用apt-get：
sudo apt-get update
sudo apt-get install -y snapd
#sudo apt-get install -y xpdf
sudo snap install okular
sudo apt-get install -y mailutils
sudo apt-get install -y mutt
