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):

    package_list = device.list_packages()
