为什么 apt-mark showhold 显示两个最新的软件包

在具有以下规格的 Ubuntu 服务器上：

user@server:~$ uname -mor
5.4.0-139-generic x86_64 GNU/Linux

user@server:~$  cat /etc/os-release 
NAME="Ubuntu"
VERSION="18.04.6 LTS (Bionic Beaver)"
ID=ubuntu
ID_LIKE=debian
PRETTY_NAME="Ubuntu 18.04.6 LTS"
VERSION_ID="18.04"
HOME_URL="https://www.ubuntu.com/"
SUPPORT_URL="https://help.ubuntu.com/"
BUG_REPORT_URL="https://bugs.launchpad.net/ubuntu/"
PRIVACY_POLICY_URL="https://www.ubuntu.com/legal/terms-and-policies/privacy-policy"
VERSION_CODENAME=bionic
UBUNTU_CODENAME=bionic

一切都是最新的：

user@server:~$ sudo apt update

但 apt 显示有两个暂停的软件包：

user@server:~$ sudo apt-mark showhold
docker-ce
docker-ce-cli

它们两个看起来都是最新的：

user@server:~$ sudo apt-cache policy docker-ce

我自然想知道为什么apt-mark showhold实际上显示了这两个包吗？

如果需要的话，我该如何“清理”它？

答案1

apt-mark showhold列出这些软件包，因为它们已被标记为hold。这是由您自己（其他人）完成的，根-特权或者可能通过脚本。

您可以使用

sudo apt-mark unhold <package>

取消先前设置的包裹保留，以再次允许所有操作。

请看一下man apt-mark。
