答案1
那些要自动删除的包是什么？
man apt-get
autoremove
autoremove is used to remove packages that were automatically
installed to satisfy dependencies for other packages and are now no
longer needed.
因此，删除这些未使用的包是完全安全的。
运行以下命令：
sudo apt-get autoremove
sudo apt-get clean
sudo apt-get update
然后尝试升级（如果可用）：
sudo apt-get dist-upgrade
