の作業をしようと思って、

bash

$  docker run -it kaizenjapan/dockertoppersfmprpi64_fmp:kaizenjapan /bin/bash

Status: Downloaded newer image for kaizenjapan/dockertoppersfmprpi64_fmp:kaizenjapan
To run a command as administrator (user "root"), use "sudo <command>".
See "man sudo_root" for details.

administrator@ed762ac5a5fb:~$ apt update; apt -y upgrade
Reading package lists... Done
W: chmod 0700 of directory /var/lib/apt/lists/partial failed - SetupAPTPartialDirectory (1: Operation not permitted)
E: Could not open lock file /var/lib/apt/lists/lock - open (13: Permission denied)

E: Could not open lock file /var/lib/dpkg/lock - open (13: Permission denied)
E: Unable to lock the administration directory (/var/lib/dpkg/), are you root?

sudoをつければいいだけっぽい。

bash

$ sudo apt update; sudo apt -y upgrade
