Device: Kobo aura HD, Kobo Arc, Kindle Fire HDX 8.9 , Kindle for PC
os error (2) no such file or directory

posting this in devices subforum , as the symptom appears when using send to device.
but I suspect the root cause is not a device issue

had this one time in v7 am seeing it now in v8. - twice in the last few days

I connect my sony & then try to send a book via calibre. ( a book that was edited yesterday). Calibre gives me
OSError: [Errno 2] No such file or directory

log for failure:
Traceback (most recent call last):
File "site-packages\calibre\gui2\device.py", line 890, in dispatch_sync_event

File "tempfile.py", line 228, in _mkstemp_inner
OSError: [Errno 2] No such file or directory

I then get it again ( see below) if I select view in calibre tool bar for that book ( though the book is there & is fine if I go via open path...
log for view failure:

a complete exit + restart of calibre fixes it, so it's a calibre bug, not a sony bug. after a restart I can send/ view the problem book(s) OK.

so what is happening here. it seems that calibre "forgets" where the book is?

my only other clues : calibre is always left running except for updates, so is the PC, I just use sleep / wake. I have worked on that book in sigil sometime in last couple of days so sigil will have written a revised copy back into calibre library.

this was the case with the v7 error also - work on book in sigil ( from calibre i.e. my workflow is that open with editor option in calibre launches sigil. sigil save puts revised copy back into library. 99.9% of the times there is no issue.



one more clue - maybe between edit/save of book and the attempt to send to device, i have run ccleaner which will wipe temporary files. could be it wipes too aggressively ?
