I just upgraded the system from 16.04 LTS to 18.04 LTS. Everything works fine until I tried to open pdf. It seems the document viewer could not open pdf files that look normal previously. However, those pdf files are OK as I can view them in chrome in 18.04. Any idea on how to fix the document viewer?
Here is the error message:
"Failed to load backend for 'applicaton/pdf': libpoppler-glib.so.8: failed to map segment from shared object
Here is a snapshot of the screen:

Following the suggestions of N0rbert, some additional information is attached as follows.
First, apt-cache policy libpoppler-glib8:

Note:
- For those who have similar issue, I found both Foxit Reader and qpdfview work fine on my computer and I finally decide to use Foxit reader as a workaround as its UI is more friendly in my opinion.
- Feel free to comment if additional information is required. I'll respond as soon as possible.
