Can't access Image due to 'No such file or directory' for drpall

[affanadly]

Describe the bug
I can't access any Images due to 'No such file or directory error' for the drpall-v2_4_3.fits, even when the file is successfully downloaded and verified to be available.

To Reproduce
Simply run

from marvin.tools.image import Image
im = Image('8567-3704')

Expected behavior
Gives out an error
[Errno 2] No such file or directory: '/root/sas/dr16/manga/spectro/redux/v2_4_3/drpall-v2_4_3.fits'
Full error:

@affanadly I'm not sure but looks like it might be a permissions issue(?). It looks like you're trying to write the SAS contents into /root. If that's a root level system directory, your user running marvin might not have permissions to write files/folders into that place. Can you check your permissions on /root? Or can you try setting the SAS_BASE_DIR environment variable to a new directory inside your user's home directory, or a folder where you have correct permissions. What version of Marvin are you using?

It also looks like you're using a system installation of the Python. These have been known to cause issues. We recommend using a separate Python installation, e.g. from Anaconda or Miniconda.
