I have just update my ubuntu from 12.10 to 13.04 and I would like to know what defaults are currently used ? Those of 12.10 or those of 13.04 ?
After such an update, does ubuntu uses the new defaults or keep old ones ? For example, python is still python 2.7 and I though that default version in 13.04 was python 3.
Normally the dist-upgrade updates all core "programs", which are necessary for the new version. It also changes the repository's to the newer version and then update all programs, if not a update with the update-manager (or in the terminal) should solve this problem.
To be clear that the new repos are set:
The default version of python in 13.04 is 2.7.4 (I made a clean install). But you can upgrade to python 3.
