Does your system tmp folder exist, and is it configured with the correct ownership and permissions? If not or if you're unsure what that all means... Take a look at this article which explains how the tmp folder should be configured, and how to recreate it if it was deleted : https://www.tecmint.com/restore-deleted-tmp-directory-in-linux/ If that still means nothing to you... Please post the output of Code: ls -ld /tmp
the output of ls -ld /tmp is: Code: [root@dedi ~]# ls -ld /tmp drwxr-xr-x 45 root root 8192 Jun 6 14:17 /tmp
You should read up on Linux groups and permissions. This means that only root has write permissions to the folder. Try running Code: sudo chmod 1777 /tmp .
Also I hope you don't always login as root... I know it's tempting, but it's a very bad idea. On Linux you should only ever have permissions for what you need to do, so you should use a normal user account for everything you do in your home folder, and use sudo to elevate to root only when you need to.
