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.

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.
I enabled SElinux
Re-enable SElinux:
sudo setenforce 1
Temporarily change the context for DATA + subfolders:
sudo chcon -R -t httpd_sys_rw_content_t /opt/webwork/webwork2/DATA
Test to see if the error is still resolved, and if so, make it permanent:
sudo semanage fcontext -a -t httpd_sys_rw_content_t "/opt/webwork/webwork2/DATA(/.*)?"
