Cannot get root shell in new Libertine container

nom

Using Pixel 3a, Release candidate channel, Settings.Updates says Ubuntu touch Version 9.

Just made a Libertine container through Settings.Libertine, default name, no password. Installed Libertine Tweak Tool, and used that to turn on Libertine Shell. The container ID when done is focal as shown by Settings.Libertine.

Went into terminal, and typed the command lish focal which gave me a prompt as follows.

(focal)I have no name!@ubuntu-phablet:~$

So I exited and typed the command to get a root shell in the container lirsh focal which behaved exactly as lish focal and did not give me a root shell.

How can I get a root shell?
How do I fix the no username problem?

Thank you for considering my difficulties.

Try the info in this post for getting a (fake)root shell

@arubislander , I found that using fakeroot as in the post you linked does not give a working root shell, e.g. apt install nano fails.

Here's something that did apparently work. Below "........." is an error message config.py:91 WARNING _get_maliit_address_from_dbus(): org.freedesktop.DBus.Error.Noreply: Did not receive a reply. [...]

phablet@ubuntu-phablet:~$ sudo -E bash
root@ubuntu-phablet:~# lish focal
..........
(focal)root@ubuntu-phablet:~#

Using this apt install nano worked, as did apt remove nano.

Using this su phablet indicates the user named phablet does not exist in the container. So I will attempt to add it with uid 32011 as associated with the missing name in the post you linked.

strange, on xperia x (focal) stable (OTA-3) it worked for me with a new focal container:
(I used the name focal2 because I have a focal container already)

phablet@xperia:~$ libertine-container-manager create -i focal2 -t chroot
...
phablet@xperia:~$ libertine-container-manager exec -i focal2 -c "/bin/bash"
groups: cannot find name for group ID 32011
I have no name!@xperia:~$ fakeroot
groups: cannot find name for group ID 32011
root@xperia:~# apt install nano
... (installs without error)

as mentioned in the post the missing id problem is solved by adding extrausers to the first 4 lines of /etc/nsswitch.conf within the container

passwd:         files systemd extrausers
group:          files systemd extrausers
shadow:         files extrausers
gshadow:        files extrausers

it could be that this only works for libertine containers of type chroot. I've updated the command above accordingly.

@chris Sorry for the stupid question, but I need help. How do I edit the /etc/nsswitch.conf file?

I use the fakeroot command, then:
nano /etc/nsswitch.conf
The editor says "file unwritable".
What am I doing wrong?

And second question I can't find how I can type «ctrl+o» on my phone keyboard ?

@Georg I had similar problems with Libertine.
Instead of editing the file from "within" the chroot, i just edited it from outside (as the user "phablet"):
nano /home/phablet/.cache/libertine-container/focal/rootfs/etc/nsswitch.conf

also I highly recommend using the ADB Shell or SSH
