Environment

• OS: Ubuntu 18.04
• scrcpy version: 1.16
• installation method: snap
• device model: Pixel 4a
• Android version: 11

Describe the bug When I run scrcpy:

adb server version (39) doesn't match this client (41); killing...
* daemon started successfully
connected to 192.168.50.18:5555
eater $INFO: scrcpy 1.16 <https://github.com/Genymobile/scrcpy>                                                                                                      
adb server version (41) doesn't match this client (39); killing...
* daemon started successfully
adb: error: failed to get feature set: no devices/emulators found

I think because:

$ /snap/scrcpy/current/usr/bin/adb --version

ADB=$(which adb) scrcpy

Sorry, github web is being weird but I meant to include that that gives a different error:

$ADB=$(which adb) scrcpy

What is the result of:

/usr/local/bin/androidtools/platform-tools/adb devices

?

So for some reason snap can't see your host filesystem to use your adb.

Try to use a non-snap version (= build it).

Yup, building it works (that's how I've been using scrcpy till now, it's great)

I'm having this very same problem.

Ubuntu 20.10 and Android-Studio downloaded from a repo (not snap) http://ppa.launchpad.net/maarten-fonville/android-studio/ubuntu/

this issue is caused by two versions of adb installed inthe system.. i think their package installs the ubuntu apt adb version and saves it in /usr/bin/adb

then we have /home/fabrizio/Android/Sdk/platform-tools/adb and the version from /usr/bin/adb causes this error

I removed such version and error went away

It works. Thank you so much @fabriziobertoglio1987 :)

THIS WILL REALLY HELP YOU (almost 90% of the time this might be the problem)

1. Download the latest version of ADB from the official Android developer website:

   [https://developer.android.com/studio/releases/platform-tools]

2. Extract the contents of the ADB ZIP file to a directory on your system, such as ~/Tools.

3. Add the directory containing the ADB binary to your PATH environment variable by adding the following line to your .bashrc file:

     `export PATH=$PATH:/path/to/adb-file-just-downloaded-and-extracted/`
   

4. Reload the .bashrc file by running the following command: . ~/.bashrc

5. Try running scrcpy again and see if the error message goes away.
