Hi everyone,
Not sure why all of a sudden I'm unable to download metadata. Screenshot attached. Here are the details of the message:

calibre, version 3.31.0
ERROR: Download failed: Failed to download metadata. Click Show Details to see details

Traceback (most recent call last):
File "site-packages\calibre\utils\ipc\simple_worker.py", line 289, in main
File "site-packages\calibre\ebooks\metadata\sources\worker.py ", line 102, in single_identify

File "site-packages\calibre\ebooks\metadata\sources\update.py ", line 62, in patch_search_engines
File "<string>", line 11, in <module>
ImportError: No module named polyglot.builtins

Please help. Thank you in advance.

I've got the exact same problem. Same error message.

[CWatkinsNash]

I'm having the exact same error as above, on a Portable install. Worked fine last night, and nothing has been changed / updated on my end since then.

A nearly identical thing happened to me today, of all a sudden. None of my computers can use this download feature that was working fine this morning, and I haven't installed or uninstalled anything. In fact, when I encountered the problem, I tried uninstalling the Calibre, and even my anti-virus, but it didn't work; then I realised that none of my other computers work either.

I've tried playing with the Preferences/Metadata_Download, trying to change the server and ticking and unticking options, but nothing works.

I hope anyone has a suggestion, but it seems to be server related somehow. My Internet works fine, by the way.

In fact, earlier I noticed the error "No module named polyglot.builtins", but now it says something else (see box above). This is what I get when I try again:

Yes. Same issue here. Two metadata fetches worked, and the third did not. Began 5 minutes prior to this post. I updated to Calibre 3.31, same error.

I also suddenly get the "Failed to download metadata" message, with the text below:

Using Calibre 3.31.

Worked fine earlier today, now getting same message.

In Calibre 3.31 I can no longer scrape metadata/covers for books, whenever I do I get the following error;

calibre, version 3.31.0
ERROR: Download failed: Failed to download metadata. Click Show Details to see details

Traceback (most recent call last):

It just out of nowhere started giving this error, I tried updating to 3.31 (from 3.30) i ran repair, nothing is working, to be clear, it has been working fine, I've pulled metadata/covers for thousands of books, pulled a bunch as recently as yesterday. (Win64 version)

[ps67]

me too, in Linux (Ubuntu-Kubuntu 18.04 64 bit) and Windows 10-64, calibre 3.31 and I tried to downgrade calibre to 3.30 in Windows 10 but same issue.

Having exactly the same problem.

Same problem here. Started today and seems to be independent of the version (i.e. same problem either in 3.30 ou 3.31).

[Terisa de morgan]

Same happening here: calibre 3.31 64 bits/calibre portable and callibre 3.30 portable, W10 64bit (3.30 worked prior to Friday and 3.31 I think too).

[dr_b]

Same here. I tried uninstalling and reinstalling the software with no luck. Using Windows 64-bit version 3.31.0

[theducks]

I suspect Windows updated one of the Libraries (DLL's) that Calibre depends on, which is why everyone who runs calibre on a 'connected' pc, has been hit. (I suspect that if your laptop HAS NOT connected to M$, then this has not happened. BUT, then the PI would also have no source to get data from, so who cares if it is broke )

Happening on Mac as well, so I suspect it's not an MS issue.
