##THE END##

报错是因为备份目录中文件名有特殊字符，代码解析时报错。
在用问题环境上 执行 如下python代码：

3

-- coding: utf-8 --

import os

def fun():
dir=[‘/var’, ‘/etc’, ‘/boot’, ‘/usr’]
with os.fdopen(os.open(“test.txt”, os.O_RDWR|os.O_CREAT|os.O_APPEND, 0x600), ‘a’) as file_fd:
for i in dir:
fun2(i, file_fd)

def fun2(dirname, file_fd):
if os.path.isfile(dirname):
file_fd.write(dirname + ‘\n’)
elif os.path.isdir(dirname):
file_fd.write(dirname + ‘\n’)
if not os.listdir(dirname):
return
for mian_dir,sub_dir,file_name_list in os.walk(dirname):
for file_name in file_name_list:
try:
file_fd.write(file_name + ‘\n’)
except Exception:
print(mian_dir)
return

fun()

x2openEuler_python39 test.py 执行，或者 python3 test.py 执行。

执行完 会输出 不能解析文件所在的目录，找到有问题文件 重新改名 或者 手动移动到其他 其他备份。

然后重新 升级。
