<pre><code> if (!ReadFdExactly(fd, buf, 4)) {

Try to export 
<code>export ADB_TRACE=all</code>

And rerun <code>adb devices</code>

Although not exactly the same error as the OP, I was getting a similar error in Windows:
<pre><code>❯ adb.exe start-server
error: protocol fault (couldn't read status): No error
</code></pre>
This error was related to my port proxy. It seems I had setup some rules that resulted in the adb client/server not being able to communicate with each other.
I was able to solve this by resetting my portproxy settings:
<pre><code>netsh interface portproxy reset
</code></pre>
And now I can start the adb server:
<pre><code>❯ adb.exe start-server
* daemon not running; starting now at tcp:5037
* daemon started successfully
</code></pre>

See <a href="https://stackoverflow.com/a/70490543/1235675">my answer here</a>, for me adb port <code>5037</code> was in use, killing the process using the port resolve the issue.

Uninstall and re-install ADB from Android Studio and check your path to make sure you aren't pointing to any other ADB installations.
I had no other installations but for some reason the ADB instance I had was corrupted (v <code>1.0.41</code>).
I went to Preferences &gt;&gt; Android SDK &gt;&gt; Unchecked the installed version &gt;&gt; Clicked next to uninstall.
Then I went back and re-checked the box to install it again and it worked. Still version <code>1.0.41</code>
