Libertine OTA-3 always failed in dnsmasq

[Phoenix]

I'm new in Ubuntu Touch.
I have flashed UT to my Pixel 3a and used for a week.
Everything works great until I tried to use desktop apps.
Libertine container always create failed.
here is the log:
mkdir: cannot create directory /run/dnsmasq
I've tried:

sudo su
mkdir ~/.cache/libertine-container/my-container-name/rootfs/run/dnsmasq
chmod -R 777 ~/.cache/libertine-container/my-container-name/rootfs/run

but the problem still existed.
Everytime "mkdir: cannot create directory /run/dnsmasq" log appeared,
create procedure stopped and ~/.cache/libertine-container folder was empty.
Can anyone help me solve this?

I solve this problem finally.
I found when I use Chinese locale , libertine container always create failed.
I switch to English locale and everything works fine.

Switch to English solve this problem, as long as if you did not change back to Chinese Traditional and update your libertine container at the same time.
If you update your container in Chinese Traditional locale, you will break your container installation as it tries to install dnsmasq-base again.
So the problem of trying to install dnsmasq-base in Chinese Traditional is still unsolved.

OK, actually found the solution to fix dnsmasq problem.

1. Switch to English
2. Create the Libertine container
3. Open the terminal, and edit /home/phablet/.cache/libertine-container/focal/rootfs/etc/nsswitch.conf and add the extrausers to the first 4 line to fix groups: cannot find name for group ID and I have no name! prompt
   (Note! If you have changed your container name, then replace focal with your container name.)

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

4. Now, using sudo -E bash to preserve user environment and enter the container to have working root

phablet@ubuntu-phablet:~$ sudo -E bash
[sudo] password for phablet: 
root@ubuntu-phablet:~# lish
config.py:91: WARNING: _get_maliit_address_from_dbus():	org.freedesktop.DBus.Error.NoReply: Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken.
(focal)root@ubuntu-phablet:~#

5. Install dnsmasq-base via apt. This time it should install successfully

(focal)root@ubuntu-phablet:~# apt update; apt install dnsmasq-base

6. exit the container and change the owner back to phablet on container folder
   (Note! If you have changed your container name, then replace focal with your container name.)

(focal)root@ubuntu-phablet:~# exit
exit
root@ubuntu-phablet:~# chown -hR phablet:phablet .cache/libertine-container/focal/
root@ubuntu-phablet:~#

7. Switch back to Chinese Traditional
8. Go to Libertine container settings->choose container you created->click Container actions(from upper-right options icon)->click Manage Container->Click "Update..." from update container.

Now you should be able to update the container without encounter failure of dnsmasq installation.

@wynn1212 Thank you for your help.
But I can't use command lish.
It says command not found.
But edit nsswitch.conf really solve the I have no name! problem.
Did I missed something?

@Phoenix Install Libertine Tweak Tool from OpenStore, then launch Libertine Tweak Tool, and toggle on Libertine Shell - lish
Or alternative, you can simply type libertine-launch -i focal /bin/bash in terminal after sudo -E bash
(Note! If you have changed your container name, then replace focal with your container name.)

@wynn1212 Awesome! It works! Thank you.
