Thank you for the effort, maybe this site helped a little bit. The solution i've found is a simple: sudo ufw allow out on waydroid0 to any. I was (and still am) confused about the 2 devices and how they "work" together. Now that i know which interface to deal with i can, of course, precise this rule, but i have another (Android-) firewall in the waydroid container that can handle this.

I saw that many people have this problem.

Maybe stow (Link 1, Link 2) is something for you. You will also have to mount the root partition rw and install stow, but this and the symlinks it creates won't take much space.

Try following:

• mkdir -p ~/Downloads/apt/cache && mkdir -p ~/Downloads/apt/archives && mkdir -p ~/Downloads/apt/lists && mkdir -p ~/Downloads/apt/installed

• sudo apt --download-only -o Dir::Cache="/home/phablet/Downloads/apt/cache" -o Dir::Cache::archives="/home/phablet/Downloads/apt/archives" -o Dir::State::lists="/home/phablet/Downloads/apt/lists" update

• sudo apt --download-only -o Dir::Cache="/home/phablet/Downloads/apt/cache" -o Dir::Cache::archives="/home/phablet/Downloads/apt/archives" -o Dir::State::lists="/home/phablet/Downloads/apt/lists" install stow

• cd ~/Downloads/apt/archives

• sudo mount -o remount,rw /

• sudo dpkg -i stow*.deb

• sudo apt --download-only -o Dir::Cache="/home/phablet/Downloads/apt/cache" -o Dir::Cache::archives="/home/phablet/Downloads/apt/archives" -o Dir::State::lists="/home/phablet/Downloads/apt/lists" clean

• sudo apt --download-only -o Dir::Cache="/home/phablet/Downloads/apt/cache" -o Dir::Cache::archives="/home/phablet/Downloads/apt/archives" -o Dir::State::lists="/home/phablet/Downloads/apt/lists" autoclean

• sudo apt --download-only -o Dir::Cache="/home/phablet/Downloads/apt/cache" -o Dir::Cache::archives="/home/phablet/Downloads/apt/archives" -o Dir::State::lists="/home/phablet/Downloads/apt/lists" install glmark2-data=2014.03+git20150611.fa71af2d-0ubuntu7 glmark2-es2-mir

• for f in `ls -1 *.deb`; do dpkg-deb -x $f /home/phablet/Downloads/apt/installed; done

• sudo stow --stow --dir=/home/phablet/Downloads/apt --target=/ installed

• glmark2-es2-mir

To undo:

• sudo stow --delete --dir=/home/phablet/Downloads/apt --target=/ installed

• rm -rf /home/phablet/Downloads/apt/installed/*

• sudo dpkg -P stow

• sudo apt --download-only -o Dir::Cache="/home/phablet/Downloads/apt/cache" -o Dir::Cache::archives="/home/phablet/Downloads/apt/archives" -o Dir::State::lists="/home/phablet/Downloads/apt/lists" clean

• sudo apt --download-only -o Dir::Cache="/home/phablet/Downloads/apt/cache" -o Dir::Cache::archives="/home/phablet/Downloads/apt/archives" -o Dir::State::lists="/home/phablet/Downloads/apt/lists" autoclean

• sudo mount -o remount,ro /

Eventually:

• rm -rf /home/phablet/Downloads/apt

You can also do things like:

• apt-cache -o Dir::Cache="/home/phablet/Downloads/apt/cache" -o Dir::Cache::archives="/home/phablet/Downloads/apt/archives" -o Dir::State::lists="/home/phablet/Downloads/apt/lists" madison glmark2-data

You're right. Btw. Fairphone 4 is not really image-based as the root partition is a device-mapper device (dm-0) defined as a part of the super partition. If it would be image based with an ubuntu image living at /userdata, like in the old days or other devices, i don't know, it would be easy to just extend this image. I wonder why someone chooses to install Ubuntu Touch with zero knowledge about Linux or Ubuntu but it's up to them and of course it's better for a developer to take care that they don't brake their system. As superuser you will always have to know what you're doing, SO FIRST THINK, THAN "Return".

The biggest problem i see with UT are the proprietary drivers. Even with libertine there's no e.g. hardware acceleration. By using stow and the symlinks it creates i can, at least with glmark2-es2-mir, have hardware rendering.

A pity. Than i'll have to deal with that and re-enable it after every call.

Hello, i have a Fairphone 4 with Ubuntu Touch Focal OTA-5. I'm using my phone as a gateway to the internet in a WLAN network provided by a mobile router. My problem is that during phone calls mobile data disconnects and e.g. my TV that's in the same network has no more internet, too. Internet TV or webradio stops, what is very annoying. Does someone know if this is normal or an error?

Unfortunately, because there are so many questions i still have and this lack of documentation makes it hard to learn and understand.

I expressed myself wrongly, sorry. Hardware is working fine, i think. Because of the root partition size limitation i already tried with libertine and self-made chroots or lxc containers and vnc.

That's where the problems begin, e.g. only software rendering through mesa. I've already tried a lot of things, e.g compiling libhybris against the vendor "blobs" or mesa drivers with Adreno support, but nothing works as expected.

It's okay for me, because i'm no expert. Understanding the whole system is far out of my reach, i think.

I read about the Ubuntu Touch architecture and thought about rebuilding this in a chroot, which includes mounting the android rootfs image and every other mounts, but i fear that won't be enough to have real hardware support.

I don't understand how this all works together with QML, Mir and so on. I've searched the internet a lot, but there isn't much information about that. Maybe it's a secret or something, I don't know.

Perhaps it's too hard, otherwise it would already be implemented in libertine or something.

@Device You may also have to remove user _apt with e.g.: sudo deluser _apt, otherwise it might not work, too.

@Device Have a look into your host's /etc/group. There are groups called android_net, android_net2 and android_net3. Create these in your chroot with e.g.: sudo groupadd -g 3003 android_net and add yourself to these groups with e.g.: sudo adduser phablet android_net. If this doesn't work add user root to group root, too. BUT AT FIRST (!!!) make a backup of /etc/group with sudo cp -avi /etc/group /etc/group.backup just in case something goes wrong.

P.S.: Maybe one of these android_net-groups is enough, i'm no expert. Try for yourself. THIS IS JUST A HINT TO PUT YOU IN THE RIGHT DIRECTION. As for me i've created all android_-groups in the chroot and added my user and user root to them. This maybe a security risk, i don't really know.
