It's needed for the session but not for phosh itself (hence Recommends:)
you can still run
/usr/bin/phoc -E /usr/libexec/phosh
fine. I'm not entirely clear here though if a `Depends:` wouldn't be the
better thing to do. It does not happen with GNOME Shell since the
session file is in a separate package (gnome-session). Maybe we need a
phosh-session here? I'll open a bug for that.
That said I've also changed phosh's dependencies to not Recommend
`gnome-session` but `gnome-session-{bin,common` so it's easier to build
a stripped down system since e.g. GNOME Shell can be removed.
Cheers,

Bug#968106: phosh: Shell doesn't start
Hello, With `sudo mmdebstrap --include=linux-image-amd64,live-boot,xserver- xorg-video-all,phosh,gnome-session-bin,libglib2.0-bin,gnome-settings- daemon,policykit-1,phosh-osk-stub --arch amd64 bullseye debian-live- root http://ftp.pl.debian.org/debian/` I got a working phosh setup with a 966M root. Michel Le Bihan
Bug#968106: phosh: Shell doesn't start
Hello, I added `--aptopt='Apt::Install-Recommends "true"'` to mmdebstrap options, so my command was `sudo mmdebstrap --aptopt='Apt::Install- Recommends "true"' --include=linux-image-amd64,live-boot,xserver-xorg- video-all,phosh --arch amd64 bullseye debian-live-root http://ftp.pl.debian.org/debian/`. I ended up with a 2.5G root that had gdm3 and gnome-shell that aren't quite useful or even wanted on mobile devices. When I selected Phosh as my shell and entered my password, Phosh didn't start and I ended up back on the login screen. I was able to start gnome-shell normally. Also, why would a package required for Phosh to function only be recommended? Are there setups where Phosh can be started without those packages being installed? Michel Le Bihan

This brings up the issue if phosh should pull in enough of gnome session to have the session file work and i think it should. I'll add this to the next upload. We'll go with phosh-osk-stub for now and do squeekboard | phosh-osk-stub once squeekboard is accepted. I think we don't need the libglib2.0-bin and policykit-1 dependencies, right?

Hello Michel Le Bihan, found this issue interesting and tried to get more information. First the "trap int3" originates from here [1], and seems just a consequence of missing packages.

Bug#968106: phosh: Shell doesn't start
Package: phosh Version: 0.4.3-1 Severity: grave Justification: renders package unusable Hello, On a freshly created Debian sid live system: ``` sudo mmdebstrap --include=linux-image-amd64,live-boot,xserver-xorg-video- all,phosh --arch amd64 sid debian-live-root http://ftp.pl.debian.org/debian/ sudo chroot debian-live-root passwd sudo chroot debian-live-root useradd -m -s /bin/bash -p $(openssl passwd -1 123456) user sudo chroot debian-live-root systemctl enable phosh cp debian-live-root/vmlinuz .; cp debian-live-root/initrd.img . sudo mksquashfs debian-live-root root.squashfs -comp lz4 python3 -m http.server -b localhost 8080 qemu-system-x86_64 -machine accel=kvm -m 4G -device virtio-net-pci,netdev=net0 -serial stdio -monitor vc -netdev user,id=net0,hostfwd=tcp::-:22,guestfwd=tcp:10.0.2.252:8080-tcp:localhost:8080,hostname=debian- live -kernel ./vmlinuz -initrd ./initrd.img -append "console=ttyS0 ip=frommedia boot=live nopersistence fetch=http://10.0.2.252:8080/root.squashfs; ``` (last command is to start the test VM) Phosh doesn't start. On the console I see: ``` traps: phoc[362] trap int3 ip:7f684a6d9585 sp:7ffccc2cfe90 error:0 in libglib-2.0.so.0.6400.4[7f684a69f000+81000] ``` When attempting to start it manually: ``` user@debian:~$ phoc (phoc:468): phoc-wlroots-CRITICAL **: 18:03:33.384: [backend/session/logind.c:760] Failed to get seat id: No data available (phoc:468): phoc-wlroots-CRITICAL **: 18:03:33.393: [backend/session/direct- ipc.c:30] Do not have root privileges; cannot become DRM master (phoc:468): phoc-wlroots-CRITICAL **: 18:03:33.396: [backend/session/session.c:96] Failed to load session backend (phoc:468): phoc-wlroots-CRITICAL **: 18:03:33.405: [backend/backend.c:286] Failed to start a DRM session (phoc:468): phoc-server-ERROR **: 18:03:33.407: Could not create backend [ 76.891092] traps: phoc[468] trap int3 ip:7feeea992585 sp:7ffe555d1130 error:0 in libglib-2.0.so.0.6400.4[7feeea958000+81000] Trace/breakpoint trap ``` ``` user@debian:~$ phoc -E '/usr/bin/phosh -U' -C /usr/share/phosh/phoc.ini (phoc:517): phoc-wlroots-CRITICAL **: 18:04:01.976: [backend/session/logind.c:760] Failed to get seat id: No data available (phoc:517): phoc-wlroots-CRITICAL **: 18:04:01.978: [backend/session/direct- ipc.c:30] Do not have root privileges; cannot become DRM master (phoc:517): phoc-wlroots-CRITICAL **: 18:04:01.981: [backend/session/session.c:96] Failed to load session backend (phoc:517): phoc-wlroots-CRITICAL **: 18:04:01.983: [backend/backend.c:286] Failed to start a DRM session (phoc:517): phoc-server-ERROR **: 18:04:01.986: Could not create backend ``` Starting phosh as root doesn't help: ``` root@debian:~# phosh /usr/bin/phosh: 12: gnome-session: not found (phoc:558): phoc-wlroots-CRITICAL **: 18:06:37.488: [backend/session/logind.c:760] Failed to get seat id: No data available (phoc:558): phoc-wlroots-CRITICAL **: 18:06:37.490: [backend/session/direct.c:176] Could not get current tty number: Inappropriate ioctl for device (phoc:558): phoc-wlroots-CRITICAL **: 18:06:37.494: [backend/session/session.c:96] Failed to load session backend (phoc:558): phoc-wlroots-CRITICAL **: 18:06:37.496: [backend/backend.c:195] failed to start a session (phoc:558): phoc-wlroots-CRITICAL **: 18:06:37.498: [backend/backend.c:235] failed to start backend 'drm' (phoc:558): phoc-server-ERROR **: 18:06:37.500: Could not create backend ``` root@debian:~# phoc -E '/usr/bin/phosh -U' -C /usr/share/phosh/phoc.ini (phoc:611): phoc-wlroots-CRITICAL **: 18:07:10.418: [backend/session/logind.c:760] Failed to get seat id: No data available (phoc:611): phoc-wlroots-CRITICAL **: 18:07:10.421: [backend/session/direct.c:176] Could not get current tty number: Inappropriate ioctl for device (phoc:611): phoc-wlroots-CRITICAL **: 18:07:10.425: [backend/session/session.c:96] Failed to load session backend (phoc:611): phoc-wlroots-CRITICAL **: 18:07:10.428: [backend/backend.c:286] Failed to start a DRM session (phoc:611): phoc-server-ERROR **: 18:07:10.431: Could not create backend ``` It's also possible that I missed an important step, but I couldn't find anything related in the doc.
