Hello,

I tried to upgrade my locales on debian, and got this:

Code: Select all

Setting up locales (2.3.2.ds1-11) ...
/var/lib/dpkg/info/locales.postinst: line 18: /etc/locale.gen.tmp: Permission denied
mv: cannot stat `/etc/locale.gen.tmp': No such file or directory
dpkg: error processing locales (--configure):
 subprocess post-installation script returned error exit status 1
Errors were encountered while processing:
 locales
E: Sub-process /usr/bin/dpkg returned an error code (1)


I founded this error in logs:

How to fix it?
Thanks

that's a nested function trampoline, so you can either enable EMUTRAMP on localedef (chpax -E) or disable the non-exec pages on it (chpax -sp).

Thanks, i've successfully solved that problem, but there is another one:

I havent any problems with grsec and /etc/security/limits.conf before.

Heh grsec worked fine, but i did one thing - tried to upgrade my debian packages. After upgrading lots of problems occured, especially with CAP_SYS_ADMIN on various programs (bash, sshd, postfix).

Seems I need a lot of things to learn about this great security system ;o)
