It is not,both sides are playing hardball,India wants full production,ToT and export rights whereas Russia wants the deal to be similar to Su-30 MKI deal.Russia will ultimately realise that Modi govt. is here to stay and will sign the deal
Japan's Mitsuibishi X-2 Shinsin is another 5th generation fighter we can partner with.Japan is not at all reluctant to transfer technology(they will do huge ToT+Full make in India for advanced tech like Shinkansen).Russians have looted us on various occasions.
73% of parts of Su-30 MKI are made in India,and about 51% of value.Greater indigenization is not possible due to contract which specifies metals,nuts,bolts etc to be sourced from Russia
