Hello Bilal,
Now, only two CST errors remain. I think I have an empty folder that is why it is. In attachment, blas0 is the error message and blas is that folder.
Good to know. While the screenshots are helpful having actual textual logs produced by the commands I had suggested would actually be preferable since they would record all output not just what fits on screen. The would also let me copy and paste the path rather than having to type it in by hand.
This still looks like part of the repository failed to download.
My suggestion would be to remove the offending directory like so:
rm -rf /home/bilal/Cactus/arrangements/ExternalLibraries/BLAS
and run GetComponents once more (making sure to keep a log).
Yours, Roland
