I use Ubuntu Linux 14.04 LTS. My all-in-one scanner and printer worked well with xsane 0.998 until I upgraded the hplip driver 3.16.2. This resulted in a number of inconveniences (for example, one other post on AskUbuntu).
Concerning the scanner, after upgrading the driver and attempting to scan a document, I was then presented with a dialogue that asked me to choose between two options. This request seemed unusual to me since I can't recall to have faced it in previous hplip upgrades. I inadvertently chose for what appeared to me the most appropriate selection, but this proved me wrong. Unfortunately I cannot recall much more details about this incident.
Ever since, as I try to start the scanner GUI, I am presented with the following error dialogue:
My perceptions about the points raised there are: 1. It may well be now, but wasn't certainly so earlier. 2. Not applicable, the device is nice and ready. 3. It never has been the case earlier as I always worked through the GUI. 4. Unclear 5. Unclear 6. I haven't installed any more version of SANE
Whatever the reason is, could someone please guide me through the process of finding the cause for trouble and fixing it. My objective would be to restore the functionalities prior to this upgrade. Thanks in advance.
Added This issue seems to be also linked to greater problems with hplip that I have raised in this other post hplip 3.16.2: no installed HP device found (while CUPS finds it)
