betsywallace Hi
Kindly try the following as given below:
--> If the file/folder permissions are correct on the tmp folder. Typically, they should be chmod 755.
--> If you are running a cPanel/WHM environment, then the folder should be owned by the cPanel user. If you're running Plesk, then the folder should be owned by www-data.
--> Also, You may try to install the updated package of extension with other methods too as outlined here
