Since 2.6.0, shell command with serial on ubuntu system will raise adbutils.errors.AdbError: unknown host service

[yinkh]

import adbutils
import os
port = int(os.getenv('ANDROID_ADB_SERVER_PORT', 5037))
client = adbutils.AdbClient(host="127.0.0.1", port=port)
serial = '7aa358b3'
#device = client.device(serial)
device = client.device_list()[0]
package_list = device.list_packages()
print(package_list)

will get error:

Traceback (most recent call last):
  File "/home/opt//demo.py", line 8, in <module>
    package_list = device.list_packages()
                   ^^^^^^^^^^^^^^^^^^^^^^

    raise AdbError(self.read_string_block())
adbutils.errors.AdbError: unknown host service

downgrade to 2.5.0 is good. and same code and same adbutils on windows is good.

windows adb server version is Android Debug Bridge version 1.0.41 ubuntu adb server version is Android Debug Bridge version 1.0.39

this code cause new bug

@codeskyblue Hi guys, 我也发现了这个问题：在ubuntu环境下用2.6.0以上的版本执行shell会弹"unknown host service"的问题，降级到2.5.0没问题，但由于check_okey方法涉及到的地方有点多，能麻烦您看下吗 diff:

I'm experiencing the same issue using adbutils==2.8.0

Traceback (most recent call last):
  File "/home/automation/rabbit/tests/robot/os/linux/serial_secure_boot/test_serial_secure_boot.py", line 266, in test_adb_shell_tryout
    d.shell('echo "Device is alive"')

update adb version to 1.0.41 or use adbutils==2.5.0
