Tizen 6.0 widget error

I have developed a widget that works on SmartTVs with TIZEN 4.0.
I want to compile it to work on TIZEN 6.0, but it gives an error.
“Invalid format of certificate in signature.:<-2>”
How can I solve that?

At what point does it give this error? I think you just need to create a new Samsung Tizen Distributor certificate. If this isn’t published in the TV Seller Office you may want to create a new Author’s Certificate as well.

If that doesn’t help please open a support request in the TV Seller Office and be more precise on when and how you are getting this error.
