如何在没有互联网连接的情况下删除ntp？

Question

我被要求通过ntp同步ubuntu 20。通常我在这次任务中使用了系统时间同步。在这台电脑上，我做了timedatectrl，得到了：

$ timedatectl
               Local time: Mon 2021-03-08 10:24:24 -05
           Universal time: Mon 2021-03-08 15:24:24 UTC
                 RTC time: Mon 2021-03-08 13:23:56
                Time zone: America/Bogota (-05, -0500)
System clock synchronized: no
              NTP service: n/a
          RTC in local TZ: no

然后我看到ntp也被安装了(顺便说一句，这是ubuntu 20的默认设置吗？)所以我下载了systemd-timesyncd rpm，把它移到这台pc上，然后运行：

~$ sudo dpkg -i systemd-timesyncd_245.4-4ubuntu3_amd64.deb
dpkg: regarding systemd-timesyncd_245.4-4ubuntu3_amd64.deb containing systemd-timesyncd:
 systemd-timesyncd conflicts with time-daemon
  ntp provides time-daemon and is present and installed.

dpkg: error processing archive systemd-timesyncd_245.4-4ubuntu3_amd64.deb (--install):
 conflicting packages - not installing systemd-timesyncd
Errors were encountered while processing:
 systemd-timesyncd_245.4-4ubuntu3_amd64.deb

冲突的包是ntp，所以我尝试删除它：

~$ sudo apt remove ntp

E: Unable to fetch some archives, maybe run apt-get update or try with --fix-missing?

将删除下列软件包: ntp将安装以下新包: systemd-timesyncd

但由于没有互联网连接，所以无法下载并安装，然后退出。

知道怎么处理这事吗？

我下载了systemd-timesyncd_245.4-4ubuntu3.3_amd64.deb，把它移到了/var/cache/apt/archives/ ran apt remove ntp -y

一切都好了
