Executing semanage returns that Python 'Plural forms expression could be dangerous'

Question

Returning to the same issue. I am receiving some error in python when adding semanage rules:

# semanage port -a -t http_port_t -p tcp 29200
Traceback (most recent call last):
  File "/sbin/semanage", line 32, in <module>

    t = _translations.setdefault(key, class_(fp))

    raise ValueError, 'plural forms expression could be dangerous'
ValueError: plural forms expression could be dangerous

After some readings I have found some topics, that stats, that adding swap would help. I have added 700MB,nope, no help, then added 4GiB, but still, no help. I see nothing special in /var/log/messages or dmesg...

Also I try to check audit2why or audit2allow but I get error:

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

Locale:

# locale

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

what else could be useful? I know I have missed something, but what?

Answer 1

It appears you have found a program which is not fully translated into your language. Try running it as:

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

I was able to reproduce your problem by changing my language to yours, i.e.:

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

But when i use a different language, it works:

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