Was about to bang my head into the wall to fix various error coming while installing plone 4.1.3 in my new kubuntu 11.10 installation.
Also I tried to get help in plone.org support but we should not expect our friends working in new years vacation..
copied from chat log there:
I am having this problem https://dev.plone.org/ticket/12243
[22:49] described in the link
[22:49] I want to use the plone python
[22:49] but my install fails like this:
[22:49] Compiling and installing readline local libraries … Installing Python 2.6.7. This takes a while… Patching for Debian/Ubuntu Multiarch Patching for thread size Patching for disabled ssl2 Installing distribute… /home/tareq/DATA/projects/SITS_FOLDER/sits_4_1/Python-2.6/bin/easy_install miss
[22:49] and in log file
[22:50] File “/home/tareq/DATA/projects/SITS_FOLDER/sits_4_1/Python-2.6/lib/python2.6/hashlib.py”, line 138, in sha224 = __get_builtin_constructor(‘sha224′) File “/home/tareq/DATA/projects/SITS_FOLDER/sits_4_1/Python-2.6/lib/python2.6/hashlib.py”, line 66, in __get_builtin_constructor import _sha256 ImportError: No module named _sha256
[22:50] Please help
[22:50] I am trying to install plone4.1.3
[22:50] my linux version is kubuntu 11.10
[22:50] 64
THEN THE SOLUTION WAS:
$sudo apt-get install build-essential
go to your plone unified installer folder
./install.sh standalone
I am not 100% sure that the sudo apt-get install build-essential was the fix as I have installed various things in my kubuntu,
But the install worked just after I did sudo apt-get install build-essential
Thanks to this blog http://ubuntuforums.org/archive/index.php/t-903477.html
Hope this can save someone from banging head
