Snap vesion 8

I’ve been using SNAP version 6 for longtime without any problem.
I’ve now updated for version 8 and I am experiencing problems in processing interferograms.
The error in Interferogram formation is
“org.jblas.NativeBlas.dgemm(CCIIID[DII[DIID[DII)V)”
does someone know how to solve the problem.
I’ m working with Ubunto 18.04.5 LTS

have you seen these FAQs? https://senbox.atlassian.net/wiki/spaces/SNAP/pages/1898577958/S1TBX+FAQs#On-Linux-I-get-the-error-org.jblas.NativeBlas.dgemm(CCIIID[DII[DIID[DII)V

The problem is solved.
It requires the installation of libgfortran5
thanks
