Hello, I'm getting check_ssl error issue in v2.4.4.sp2 in CentOS 7. Initially after installation this did not occur, no problem, server was working properly and now Apache is not starting anymore. I look at the error code and try to fix the problem according to previous tickets but didn't differ. I tried below commands to no avail: localedef -c -f UTF-8 -i en_US en_US.UTF-8 export LC_ALL=en_US.UTF-8 export LANG=en_US.UTF-8 Test follows: root@keyserver ~]# locale LANG=en_US.UTF-8 LC_CTYPE="en_US.UTF-8" LC_NUMERIC="en_US.UTF-8" LC_TIME="en_US.UTF-8" LC_COLLATE="en_US.UTF-8" LC_MONETARY="en_US.UTF-8" LC_MESSAGES="en_US.UTF-8" LC_PAPER="en_US.UTF-8" LC_NAME="en_US.UTF-8" LC_ADDRESS="en_US.UTF-8" LC_TELEPHONE="en_US.UTF-8" LC_MEASUREMENT="en_US.UTF-8" LC_IDENTIFICATION="en_US.UTF-8" LC_ALL=en_US.UTF-8 [root@keyserver ~]# check_ssl unable to load certificate 139898384406432:error:0906D06C:PEM routines:PEM_read_bio:no start line:pem_lib.c:703:Expecting: TRUSTED CERTIFICATE Traceback (most recent call last): File "/usr/local/bin/check_ssl.py", line 13, in time_tup = time.strptime(t, '%b %d %H:%M:%S %Y %Z') File "/usr/lib64/python2.7/_strptime.py", line 467, in _strptime_time return _strptime(data_string, format)[0] File "/usr/lib64/python2.7/_strptime.py", line 325, in _strptime (data_string, format)) ValueError: time data '' does not match format '%b %d %H:%M:%S %Y %Z' [root@keyserver ~]# locale-gen en_US.utf8 -bash: locale-gen: command not found
