Permission denied error, can't run sage

[Dushyant_Sapre]

Hi,

I've been using Ubuntu for a few months. I installed sagemath after extracting the tar file . In the terminal, when I go to the directory of sage and type " ./sage " , it says permission denied. I googled about and mostly found people saying use 'sudo' before my command. When I do that it says command not found.Have a look-

Hello and welcome to the forums

There are a number of reasons why a supposedly executable file might not execute - let's start with the following information from the terminal



ls -ld sage

file sage

uname -a

Also lets see what's in the sage directory, with just
ls
from within that directory.
Also, please post the output from
mount
for that partition. Some subtle "can't execute" problems may result from mounting with the no execution flag.

This is what I got.

The sage script should be executable by default when you unpacked the tar archive - I suspect that your issue is that /media is a non-Unix filesystem (such as a NTFS partition) without the necessary support for Linux permissions (see ubfan1's post above)

You could try running it as



bash sage


but really a better solution would be to unpack the archive to a more suitable location (somewhere in your regular /home/dsap29 directory for example)

I reinstalled sage in the home/dsap29 directory and it worked. Thanks a lot!
