[petsc-users] Error installing PETSc with --download-f2cblaslapack

[Blondel, Sophie]

Correct, I tried a few different python versions and mpi versions, conda is providing the external dependencies. Maybe it wrongly points to some base builds instead of the specific environment I set up.

Best,

Sophie

  I assume you tried rerunning a few times? It seems like possibly a flaky filesystem problem.

The version of PETSc you are using is out-of-date, we recommend updating to the new release
 Available Version: 3.23.3   Installed Version: 3.22.2

Let me know what additional information I can provide to help identify the issue.

Best,

Sophie
