I've tried to upgrade my existing 1.6.2.0-Installation to 1.7.0.2 via the downloader by the following command:
./mage upgrade http://connect20.magentocommerce.com/community Mage_All_Latest --force
This results in the following message:
Already installed: community/Mage_All_Latest 1.6.2.0, skipping [...] [...]
But if I'm checking "./mage list-upgrades" I can see that there is an update for Mage_All_Latest:
Mage_All_Latest: 1.6.2.0 => 1.7.0.2
Next I tried to install 1.7.0.2 by the following command:
./mage install http://connect20.magentocommerce.com/community Mage_All_Latest --force
but this (re-)installs only the 1.6.2.0-Packages.
I also tried this two commands setting explicit version numbers but is still doesn't work.
Any idea?
