How do I make this work on Ubuntu 24.04? Device could not be connected (state=offline)

[savonbeldi]

I followed the instructions for 22.04, because there are non for 24.04. It shouldn't be that different though. https://github.com/remote-android/redroid-doc/blob/master/deploy/ubuntu.md

the command sudo modprobe ashmem_linux resulted with an error, but its optional anyways:

$ sudo modprobe ashmem_linux
modprobe: FATAL: Module ashmem_linux not found in directory /lib/modules/6.8.0-51-generic

I have downloaded adb from https://dl.google.com/android/repository/platform-tools_r28.0.1-linux.zip.

$ adb version
Android Debug Bridge version 1.0.40
Version 4986621
Installed as /opt/android/platform-tools/adb

Then start android 15:

$ docker run -itd --rm --privileged --pull always -v ~/data:/data -p 5555:5555 redroid/redroid:15.0.0_64only-latest                                             
15.0.0_64only-latest: Pulling from redroid/redroid
Digest: sha256:cba8c4a7630a8b9091cb20b3e44dd9dd65371a6c1116884af41bb786919bbba3
Status: Image is up to date for redroid/redroid:15.0.0_64only-latest
1bd8d93a31875c1fa0b3727e942ee23fb04fb7298a7d821ac3a49878f80e0ee1

Next step is adb connnect, which yields:

adb connect localhost:5555
* daemon not running; starting now at tcp:5037
* daemon started successfully
failed to connect to localhost:5555

Running it again yields:

adb connect localhost:5555
already connected to localhost:5555

Then the last step, scrcpy could not find the device...:

$ scrcpy -s localhost:5555
scrcpy 1.25 <https://github.com/Genymobile/scrcpy>
adb server version (40) doesn't match this client (39); killing...
* daemon started successfully
ERROR: Could not find ADB device localhost:5555:
ERROR:         (tcpip)  emulator-5554                  offline  
ERROR: Server connection failed

adb devices yields:

$ adb devices
List of devices attached
emulator-5554	offline
localhost:5555	offline

What am I doing wrong?

@zhouziyang Thanks for responding. I got more info and the logs. I tried both android 12 and 15 images. Also made sure that --pull always.

First of all, I was using a snap version of scrcpy. I downloaded the binaries from their github repo instead: https://github.com/Genymobile/scrcpy/releases/tag/v3.1

The initial error resolved but now I am stuck at this:

$ adb connect localhost:5555
* daemon not running; starting now at tcp:5037
* daemon started successfully
failed to connect to localhost:5555

$ adb connect localhost:5555
already connected to localhost:5555

$ adb devices
List of devices attached
localhost:5555	offline

$ scrcpy -s localhost:5555
scrcpy 3.1 <https://github.com/Genymobile/scrcpy>
ERROR: Device could not be connected (state=offline)
ERROR: Server connection failed

The logs:

I added the logcat and dmesg logs as attachments because their long.

dmesg.txt
logcat.txt

[zhouziyang]

many Abort message: 'Binder driver could not be opened. Terminating.' error logs.

Try

apt install linux-modules-extra-`uname -r`
modprobe binder_linux devices="binder,hwbinder,vndbinder"

docker restart <your-redroid-container>
