执行 semanage 返回 Python“复数形式表达可能很危险”

回到同一个问题。在添加 semanage 规则时，我在 python 中收到一些错误：

# semanage port -a -t http_port_t -p tcp 29200
Traceback (most recent call last):
  File "/sbin/semanage", line 32, in <module>
    import seobject
  File "/usr/lib64/python2.7/site-packages/seobject/__init__.py", line 36, in <module>
    import sepolicy
  File "/usr/lib64/python2.7/site-packages/sepolicy/__init__.py", line 21, in <module>
    codeset='utf-8')
  File "/usr/lib64/python2.7/gettext.py", line 495, in install
    t = translation(domain, localedir, fallback=True, codeset=codeset)
  File "/usr/lib64/python2.7/gettext.py", line 480, in translation
    t = _translations.setdefault(key, class_(fp))
  File "/usr/lib64/python2.7/gettext.py", line 180, in __init__
    self._parse(fp)
  File "/usr/lib64/python2.7/gettext.py", line 317, in _parse
    self.plural = c2py(plural)
  File "/usr/lib64/python2.7/gettext.py", line 93, in c2py
    raise ValueError, 'plural forms expression could be dangerous'
ValueError: plural forms expression could be dangerous

读了一些资料后，我发现了一些主题，统计数据显示添加交换会有所帮助。我添加了 700MB，没有帮助，然后添加了 4GiB，但仍然没有帮助。我在 /var/log/messages 或 dmesg 中没有看到任何特别之处...

我还尝试检查 audit2why 或 audit2allow 但出现错误：

cat /var/log/audit/audit.log | audit2why 
plural forms expression could be dangerous

区域设置：

# locale
LANG=lt_LT.UTF-8
LC_CTYPE="lt_LT.UTF-8"
LC_NUMERIC="lt_LT.UTF-8"
LC_TIME="lt_LT.UTF-8"
LC_COLLATE="lt_LT.UTF-8"

LC_ADDRESS="lt_LT.UTF-8"
LC_TELEPHONE="lt_LT.UTF-8"
LC_MEASUREMENT="lt_LT.UTF-8"
LC_IDENTIFICATION="lt_LT.UTF-8"
LC_ALL=

还有什么有用的东西？我知道我错过了一些东西，但是什么呢？

答案1

似乎您找到了一个未完全翻译成您的语言的程序。请尝试以下列方式运行它：

LANG=en_US.UTF-8 semanage port -a -t http_port_t -p tcp 29200

通过将我的语言改为您的语言，我可以重现您的问题，即：

# LANG=lt_LT.UTF-8 audit2why < /var/log/audit/audit.log
plural forms expression could be dangerous

但当我使用不同的语言时，它有效：

# LANG=en_US.UTF-8 audit2why < /var/log/audit/audit.log
Nothing to do
