cannot upload files

Dear All,
After making recent updates, it seems that I can no longer upload files using the file manager. When I check the permissions on the directory and files, it shows apache as the owner, which seems the way it should be. Nevertheless, I get the following error message when trying to upload files.
failed to write upload info file /opt/webwork/webwork2/DATA/uploads/e20d1b50-7a4f-4aeb-80f7-5887b5014b7c.info: Permission denied at /opt/webwork/webwork2/lib/WeBWorK/Upload.pm line 112.

Should there be another owner?

Hi Richard,

What are the permissions on the uploads directory?

Here is what I have:

wwadmin@wwserver:/opt/webwork/webwork2/DATA$ ls -l
total 16
drwxrwsr-x 4 wwadmin wwdata 4096 2010-08-19 17:38 ./
drwxr-xr-x 13 wwadmin wwadmin 4096 2010-08-19 17:38 ../
drwxrwxr-x 6 wwadmin wwdata 4096 2010-08-19 17:38 .svn/
drwxrwsr-x 3 wwadmin wwdata 4096 2010-08-19 17:38 uploads/


This is with a standard Ubuntu installation. Apache is in the group wwdata.

Arnie,
Thanks. You have cleared up the problem. I was looking at the wrong files/directories. Once I changed the directories you indicated to have the proper ownership, the troubles went away.
Thanks again.

Arnie,

I am setting up webwork on RHEL 8 using tutorial https://webwork.maa.org/wiki/Installation_Manual_for_2.16_on_RHEL8.

I am facing the same issue permission denied issue while trying to upload the files:

failed to write upload info file /opt/webwork/webwork2/DATA/uploads/5E3C41DE-5935-11EC-9AC5-5BAE1AA73A45.info: Permission denied at /opt/webwork/webwork2/lib/WeBWorK/Upload.pm line 112.

The permissions for the /opt/webwork/webwork2/DATA/ are:

 0 drwxrwsr-x.  3 wwadmin apache     21 Dec  2 10:18 DATA

Where wwadmin is a standard user (added to sudoers) and apache is the server group.

Any thoughts on it

Have you completed the SELinux part on the manual page?

Yes, I did after your message I rerun those and the following is the output:

Looks like it is not having issue.


Following are the permissions for a Test course: wwadmin@QWEBWORK:\ [ /opt/webwork/courses/Test ]$ ls -ls
total 8

Have you double-checked the permissions on /opt/webwork/webwork2/DATA/uploads?

I think after disabling SeLinux it started to work for him. Not sure if there is an issue with the SeLinux part or not in the installation notes.
