Hi, I have try yo launch anbox but I have: "anbox session-manager
[ 2021-06-16 20:46:21] [session_manager.cpp:133@operator()] Failed to start as either binder or ashmem kernel drivers are not loaded". The secure boot is disable and I have do:

jourdelune@jourdelune-OptiPlex-3050:~$ sudo modprobe binder_linux
jourdelune@jourdelune-OptiPlex-3050:~$ lsmod | grep -e ashmem_linux -e binder_linux

Hi. What I tried and worked for me, precisely yesterday, was to remove the edge branch, and install the beta version. And added ashmem_linux and binder_linux modules to startup. Just do $ sudo nano /etc/modules and add
ashmem_linux
binder_linux
Not sure if the reason of working was that, or the installation of beta branch with
$ sudo snap install anbox --beta --devmode
Besides, you have these lines,
kernel:
version: Linux version 5.4.0-74-generic (buildd@lgw01-amd64-038) (gcc version 9.3.0 (Ubuntu 9.3.0-17ubuntu1~20.04)) #83-Ubuntu SMP Sat May 8 02:35:39 UTC 2021
binder: false
ashmem: true
my best bet is the module is not in the kernel, so you will have to build it from source or use the additional PPA that carry them and add it to startup
Please leave an answer either it worked for you or not.

[Jourdelune]

what is PPA ?

[Bonteruel]

A third party repository.
https://docs.anbox.io/userguide/install_kernel_modules.html}
in that link you can see how to add it.

Hi. I upgrade Debian 10 to 11, and is no longer necessary build modules ashmem and binder, aparently integrated in new kernel. Don't remember if I have beta or devmode branch installed. Im logged in windows by the moment. I'll check later. Already installed some apps like Cool is best and music tutor, not fully supported.

[Jourdelune]

okay^^
