Only Typo3.org Main Repository is available for Retrieve / Update
Even if I select another mirror in "Settings" tab, I only got this choice for Retrieve / Update in "Remote repository" tab.
Also, in Database Update tab for Extension Manager, when trying to import static data, it always shows that table "sys_ter" needs to be altered but already exists.
Do I have to drop it then make updates ?
