Error of Interferogram in SNAP

[thho]

Read this thread from the linked post until the end. Be sure to read it completely to check the latest issues with that error and up to date SNAP installations:

Error in SAR image corregistration: Error: [Nodeld: CreateStack] org.jblas.NativeBlas.dgemm(CCIIID[DII[DIID[DII)V)

I’m having the same issue, the only difference being I’m using Sentinel-1 data. sudo apt install libgfortran3 appears not to have made any difference.
