-
Hello, howto debian chroot
- Create chroot
mkdir -p /home/phablet/Documents/debian sudo debootstrap \ --include=btop,chromium,firefox-esr,maliit-inputcontext-gtk2,maliit-inputcontext-gtk3 \ --arch arm64 \ bookworm \ /home/phablet/Documents/debian \ http://deb.debian.org/debianchroot created into /home/phablet/Documents/debian
- Create user phabet
sudo chroot /home/phablet/Documents/debian useradd -m phablet --uid 32011- Configure chroot for dbus, wayland, sound ... for user phablet
Added to /home/phablet/.bashrc into chroot
export XDG_RUNTIME_DIR=/run/user/32011 export WAYLAND_DISPLAY=wayland-0 export DISPLAY=:0 export XSOCKET=/tmp/.X11-unix/X0 export DBUS_SESSION_BUS_ADDRESS=unix:path=/run/user/32011/bus export USER=phablet #keyboard export QT_IM_MODULE=Maliit export GTK_IM_MODULE=Maliit- Start chroot as phablet user
MCHRDIR=/home/phablet/Documents/debian cp /etc/hosts ${MCHRDIR}/etc/hosts cp /etc/resolv.conf ${MCHRDIR}/etc/resolv.conf mount -o bind /dev ${MCHRDIR}/dev mount --bind /dev/pts ${MCHRDIR}/dev/pts mount --bind /proc ${MCHRDIR}/proc mount --bind /tmp ${MCHRDIR}/tmp mount --bind /sys ${MCHRDIR}/sys mount --bind /run ${MCHRDIR}/run #dbus mount -o bind /var/run/dbus/ ${MCHRDIR}/var/run/dbus #shm (chromium) mount --bind /dev/shm/ ${MCHRDIR}/dev/shm #wayland mkdir -p ${MCHRDIR}/run/user/32011 mount --bind /run/user/32011 ${MCHRDIR}/run/user/32011 chroot --userspec=phablet:phablet ${MCHRDIR} \ /usr/bin/env -i \ HOME=/home/phablet/ \ TERM="$TERM" \ PS1='(lfs chroot) \u:\w\$ ' \ PATH=/usr/bin:/usr/sbin \ /bin/bash --login sleep 5 umount ${MCHRDIR}/dev/shm umount ${MCHRDIR}/var/run/dbus/ umount ${MCHRDIR}/run/user/32011 umount ${MCHRDIR}/run umount ${MCHRDIR}/sys umount ${MCHRDIR}/proc umount ${MCHRDIR}/dev/pts umount ${MCHRDIR}/dev umount ${MCHRDIR}/tmpI've tested chromium firefox all seems works here on my pixel3a focal RC
TIP
- You can change PS1 in your chroot ~/.bashrc for identify quickly if you are into the chroot :
PS1='chroot \u@\h:\w\$ 'After login in your chroot
chroot phablet@ubuntu-phablet:/home/phablet$- Change DPI
cat ~/Documents/debian/home/phablet/.Xdefaults
xterm*faceName: DejaVu Sans Mono xterm*faceSize: 10 Xft.dpi:200You can adapt Xft.dpi with your display
- VNC xfce4 works
I can use my pixel3a with lomiri as mobile, And for a little desktop VNC if I don't have my dongle. I love this device

@Bouleetbil Hi, do you see it behave better than libertine?
-
@jarop
Hi,
For me yes, but it's not really user friendly-
I can login as root or regular user.
libertine can not : https://forums.ubports.com/topic/8797/libertine-focal-don-t-find-group-id?_=1698153549115 -
I can add new repo
https://gitlab.com/ubports/development/core/libertine/-/issues/124 -
I can add additional bind-mounts
https://gitlab.com/ubports/development/core/libertine/-/issues/120 -
I can choose the GNU/Linux distribution as postmarket
But you should start the applications in command line, the desktop files are not into the lomiri launcher.
For chroot should more user friendly :
Create a systemd service user for mount all necessary on startup
Create a launcher or adapt lomiri-app-launch for start the application in this chroot
Added .desktop from chroot to lomiri launcher -

@Bouleetbil Nice!
I didn't use chroot but instead installed directly in the root long time ago and I used to use xfce4 via x-forwarding on my work laptop and UT development 
In case you're insterested, I think Junest is a similar solution and some people has made it work on UT.

Hey, this look great for later!
So if I get this right, you can install .deb as a ordinary system? Blender, whatsapp client, available browsers?
And is there an app like Alacarte so you can create shortcuts with commands? So instead of using command line, you have an icon for that command? Often use that in normal linux.
Best regards.

Hi @Bouleetbil - thanks for this. I'm also using a Pixel 3a (Focal) and thought I'd give this a try, but it doesn't seem to be working for me.
After entering the first block of code (Create chroot), it was busy doing stuff for about 10 mins, but then eventually failed with:
W: Failure while configuring base packages. This will be re-attempted up to five times. W: See /home/phablet/Documents/debian/debootstrap/debootstrap.log for details (possibly the package dconf-service is at fault)Looking thorugh the log file I just see lots of dependency errors, e.g.
dpkg: error processing package firefox-esr (--configure): dependency problems - leaving unconfigured Errors were encountered while processing: dconf-service dconf-gsettings-backend:arm64 libgtk-3-common libgtk-3-0:arm64 chromium maliit-inputcontext-gtk3 firefox-esrAny ideas?
Thanks,

@moodroid
hello try to create chroot wirhout package and install packages manualy with aptmkdir -p /home/phablet/Documents/debian sudo debootstrap \ --arch arm64 \ bookworm \ /home/phablet/Documents/debian \ http://deb.debian.org/debian -
Hi,
So I tried this, But
sleep 5
umount ${MCHRDIR}/dev/shm
umount ${MCHRDIR}/var/run/dbus/
umount ${MCHRDIR}/run/user/32011umount ${MCHRDIR}/run
umount ${MCHRDIR}/sys
umount ${MCHRDIR}/proc
umount ${MCHRDIR}/dev/pts
umount ${MCHRDIR}/dev
umount ${MCHRDIR}/tmppart seems problematic as I have to be a superuser. And I dont know thte command how to start anything from terminal.
Any ideas?

@Rinkeby
Hi, I've created a repo gitlab for install chroot debian
https://gitlab.com/bouleetbil/ubports-scripts#installationit provided a systemd service for mount debian chroot https://gitlab.com/bouleetbil/ubports-scripts/-/blob/main/.config/systemd/user/debian-mount.service?ref_type=heads
After you can create some alias
#debian chroot alias debian='/home/phablet/bin/debian-chroot.sh /bin/bash --login' alias firefox='/home/phablet/bin/debian-chroot.sh firefox' -
Thats amazing of you. I hope this get adopted. I will lean in to it a bit later.
So, two more happy question, I see wayland in your code, does this make interface smoother? At the moment i run Firefox through libertine, some add-ons and its actually better than click apps, including smoothness. However, it can be a touch better like in waydroid, running wayland.
question nr two: Have you tried something more exotic, like Brave or Libre office?
-
@Rinkeby
I've tested xfce4, vnc, libreoffice, ssh that works
I've some issues with the virtual keyboard and chromium
For firefox with firefox-esr-mobile-config it's not bad but the keyboard hide the search bar.I use this chroot with a physical keyboard and a wireless display as a little computer.
BTW I've added my script for enable wake up on tap on startup https://gitlab.com/bouleetbil/ubports-scripts#enable-wake-up-on-tap-on-startup
-
amazing!
But sorry, I have another question (Keeps the thread on top tough) and that is that I see libertine now in your script. will it messup my already existing libertine setup. because I got firefox up and nice with ad ons. and will it be a conflict?
best regards.
-
@Rinkeby
Hello, no problem, you will have any conflict. It's just the official chroot for ubports.
I use it for test libertine. -
Thanks @Bouleetbil
I did try the new command to create the chroot, and it worked fine. But I was still struggling with some of the later steps.
Hopefully this will make it simpler - looking forward to trying it out… -
-
@Rinkeby hello don't lanch install.sh with root. The scripts use sudo
-
welp. regardless, nothing works. You done great work. But, Im just lost and it doesnt work here and there.
take your time to see and test if you can make a manual or a full install script. It all got a bit fragmented perhaps?
-
Hi @Bouleetbil - I've just tried, and got this:
phablet@ubuntu-phablet:~/ubports-scripts$ ./install.sh cp: cannot create regular file '/home/phablet/.config/systemd/user/debian-mount.service': No such file or directory Failed to enable unit: Unit file debian-mount.service does not exist.Any ideas?
Thanks

Came out harsh for some reason. But what I meant was, that I really hope to see something that works. Because I long for it!
