I found that, in fact, libjpeg8 is only a dependency package for libjpeg-turbo8.
user@lubuntu:~$ dpkg -l | grep libjpeg ii libjpeg-turbo8:amd64 1.4.2-0ubuntu3.1 amd64 IJG JPEG compliant runtime library. ii libjpeg-turbo8:i386 1.4.2-0ubuntu3.1 i386 IJG JPEG compliant runtime library. ii libjpeg8:amd64 8c-2ubuntu8 amd64 Independent JPEG Group's JPEG runtime library (dependency package) ii libjpeg8:i386 8c-2ubuntu8 i386 Independent JPEG Group's JPEG runtime library (dependency package) So, the systems are using libjpeg-turbo8. The string "Premature end of JPEG file" exists also in libjpeg-turbo8 code: https://github.com/libjpeg-turbo/libjpeg- turbo/search?q=Premature+end+of+JPEG+file&unscoped_q=Premature+end+of+JPEG+file ** No longer affects: libjpeg8 (Ubuntu) -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to libjpeg-turbo in Ubuntu. https://bugs.launchpad.net/bugs/1747558 Title: JPG photo not viewable via default image viewer, but opens fine via Firefox Status in gpicview package in Ubuntu: New Status in libjpeg-turbo package in Ubuntu: New Status in mtpaint package in Ubuntu: Confirmed Bug description: Using Lubuntu i386 daily build downloaded approx 36hours ago. In documenting a separate bug, I took a photo via the inbuilt camera in my Nokia dumbphone. Low-res, small image size. Transferred from phone & saved to desktop. Opening that JPG in Image Viewer brings up the error message "Error interpreting JPEG image file (Application transferred too few scanlines)", yet the image is perfectly viewable in Firefox. Have attached the JPG in question to this bug report - the contents of this photo are also relevant to Bug 1747341.
