while pdf files should already work, it was not yet possible to build a docviewer packages with libreoffice support.
I wanted to post the steps I already did and the results

@nom
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.

I've seen that with the fakeroot command it is possible to get a root shell for libertine:

@Bouleetbil
I struggled with getting a root shell as well and tried many things, but suddenly found a quite easy way:
after logging in to the libertine focal container with

libertine-container-manager exec -i focal -c "/bin/bash"

type the command "fakeroot" and press return. I could then run apt within the container without the dpkg "requires superuser" errors.

or it is possible to use the following command to log in to libertine with user root:

libertine-container-manager exec -i focal -c "/bin/fakeroot"

EDIT: it might only work for libertine containers of type 'chroot'. (-t chroot when creating the container)

Did you know that the microsoft 2FA can be used with an alternative app as well (https://answers.microsoft.com/en-us/msoffice/forum/all/using-a-different-authenticator-app-for-2fa/9202e8b5-d859-445c-80fa-61c0e04a1ebf) E.g. I'm using authenticator NG for it. As I remember I've manually entered that long token that is included in the mentioned QR code to authenitcator NG and use that app now for microsoft 2FA logins.

a question: do some of you that have only morph open and it uses very much memory use uadblock ? For me (BQ Aquaris 4.5) uadblock (with all lists) added a high memory footprint to morph and webapps for me. https://github.com/ubports/ubuntu-touch/issues/1265 / https://github.com/ubports/morph-browser/issues/263
Removing the lists / turning uadblock off did not revert the effect for me, only reflashing (and then no longer use uadblock) helped.

Yesterday I tried the same for the amd64 clickable container (adding the dependendies manually and run in desktop mode), and got:

Here some screenshots to the steps described in https://github.com/ubports/docviewer-app/pull/25

If you uncomment the line "#INSTALL( DIRECTORY ${UPSTREAM_LIBS_DIR}/opt/libreoffice/lib/libreoffice/ DESTINATION ${DATA_DIR}lib/${ARCH_TRIPLET}/libreoffice )" in Click.cmake, you get a click package without libreoffice support (e.g. text and pdf files work).

If you try to open an odt file, you get the message:

If you add (e.g. in a chroot environment with clickable --container-mode) libreoffice to the dependencies, and put the line " #INSTALL(DIRECTORY /usr/lib/libreoffice/ DESTINATION ${DATA_DIR}lib/${ARCH_TRIPLET}/libreoffice )" to the Click.cmake, you get an about 80MB click package.

Again opening an example odt file, you now get:

In the logviewer you see, for example:

After adding the missing dependencies, at some point it was no longer complaining, the screen looked like:

and the corresponding log:
qml: Path of the document: /media/phablet/7873-B162/Documents/example.odt

But at that point docviewer crashed. I will not have much time currently to look into that in more detail, but at least that is where I got on Saturday...

while pdf files should already work, it was not yet possible to build a docviewer packages with libreoffice support.
