(continuing from thread “Upgrading Tomcat? “)

This is a rented KVM container I control remotely via SSH. The minimal 
Ubuntu 18.04 installation was installed by my control panel. I am on a 
rather steep learning curve and had to glean my understanding from many 
sources online. So, it was my error or misunderstanding which installed 
Tomcat 8. The installation is now live, so I wish to 'fix' it without 
breaking it.


Over all, everything seems very stable, except for the unpredictable 
behavior when I attempt to upload images or other files using the web 
interface. When I submit a new item, I get as far as the “Upload File(s)” 
step. The browse dialog works fine and I select my desired jpg image. The 
“Next” button then usually results with a “No such file or directory” 
error. I am including the Java stacktrace, in case anyone can suggest 
something from it. If you attempt this a number of times, it eventually 
accepts the submitted upload.


For now, I have given up on web form submission and am uploading everything 
directly via FTP, where the command line procedures and utilities work 
fine. 


So, help with this web-form bit-stream problem upload would be welcome. I 
use an updated Firefox browser and my partner is using Edge. We both see 
the same problem. This problem might also exist when trying to upload CSV 
spreadsheets or templates.


Thanks

Dear Chris,


For what it's worth I have been running DSpace 5 and 6 with Tomcat 7.0.x 
for several years so your issues are likely not due to having an older 
Tomcat—you might want to look into those issues more (start another thread 
on this mailing list describing them)! Also, the Apache Tomcat project has 
announced (long ago) that the 8.0.x series is superseded by the 8.5.x 
series¹. Lastly, I see that Ubuntu 18.04 ships Tomcat 8.5.x with its system 
package manager². How did you manage to get 8.0.x? Are you on Ubuntu 16.04 
perhaps?


Regards,
