tftp-hpa不会在Ubuntu 20.04上注册tftpd-hpa服务。

Question

我试着按照TFTP -社区帮助Wiki安装tftp软件包，但它不会安装(至少不正确)。

user@host:/etc/default$ lsb_release -a

amd64-microcode  bsdmainutils  cron           im-config  keyboard         networkd-dispatcher  rsync     virtlockd

apt安装过程没有：

1. 创建并注册tftp-hda服务。
2. 创建/etc/default/tftpd-hpa配置文件

我原以为这两个人会发生，但他们没有。我到哪里去找面包屑/日志来解决这个问题？

您在安装包时遗漏了d，即tftp-hpa是TFTP客户端，而tftpd-hpa是服务器。

如果您运行apt show tftp-hpa并读取描述，您将看到

Description: HPA's tftp client
 Trivial File Transfer Protocol (TFTP) is a file transfer protocol, mainly to
 serve boot images over the network to other machines (PXE).
 .
 tftp-hpa is an enhanced version of the BSD TFTP client and server. It
 possesses a number of bugfixes and enhancements over the original.
 .
 This package contains the client.

另一方面，apt show tftpd-hpa会返回

Description: HPA's tftp server
 Trivial File Transfer Protocol (TFTP) is a file transfer protocol, mainly to
 serve boot images over the network to other machines (PXE).
 .
 tftp-hpa is an enhanced version of the BSD TFTP client and server. It
