如果我跑
sudo apt update
我收到一条以以下内容结尾的消息
Reading package lists... Done
Building dependency tree
Reading state information... Done
1 package can be upgraded. Run 'apt list --upgradable' to see it.
如果我然后运行
apt list --upgradable
我明白了

N: There are 15 additional versions. Please use the '-a' switch to see them.
但是，我不知道如何进行升级。如果我这样做
sudo apt upgrade
sudo apt-get dist-upgrade
然后重新启动，然后
apt list --upgradable
仍然显示

我该如何升级这个包？
