To build uwsgi on Fedora 12 (which has no easy-to-find python3 rpm), run through the rpmbuild process (shown in a previous post in more detail for nginx) and make the following changes :

wget http://kad.fedorapeople.org/packages/uwsgi/uwsgi-0.9.9.2-2.fc15.src.rpm
rpm -ivh uwsgi-0.9.9.2-2.fc15.src.rpm
rpmbuild -bb  ~/rpmbuild/SPECS/uwsgi.spec
yum install python-devel libuuid-devel jansson-devel libyaml-devel ruby-devel python3-devel python-greenlet-devel  lua-devel  ruby
# NB: python3-devel doesn’t exist…
# [...]

In order to get access to uwsgi (useful for deploying python flask projects, for instance), one needs a version of nginx > 0.8 or so. But Fedora 12 doesn’t have such a modern version : Here’s how to build it from a src.rpm from a more recent Fedora release.

# First, make sure [...]

It appears that the RPM database needs rebuilding if a yum process is killedprematurely, since it probably had the RPM db open and now it’s in an inconsistentstate.
The steps :

Kill all yum and rpm processes.

rm -f /var/lib/rpm/__db*

rpm –rebuilddb
(add -vv if you want to see what it’s doing)
Retry
yum update
