Hi

We had an old J2.5 +seblod 3.1.1 project we are migrating to J3.4.3 + Seblod 3.7.

We switched it in J3.4.3 but when we try to upgrade Seblod 3.1.1 to Seblod 3.3.7 or 3.4 or 3.5 we have the error message:

Another package is already using the named directory /administrator/manifests/packages/cck

Are you trying to install the same extension again?

Error
Error installing package

If I try to install Seblod 3.6 or 3.7 (some older versions of the package)  I get another error message :

1054 Unknown column 'aliases' in 'field list' SQL=SELECT id, title, name, aliases, guest, guest_only_viewlevel, groups, viewlevels, configuration, options FROM g8bin_cck_core_sites WHERE published = 1

What should I do please ?

thanks
