The "Error opening file for reading" is caused by Ubuntu's patch to libjpeg-turbo library. I opened a separate bug report for it to libjpeg- turbo package here: https://bugs.launchpad.net/ubuntu/+source/libjpeg- turbo/+bug/1031718
The error message should be nonfatal, just obscure when it appears in application logs. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1014487 Title: virtualbox: Error opening file for reading To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/virtualbox/+bug/1014487/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
