After upgrading anki I have this problem where every single time I select to sync from my desktop to anki web, I get this error message: Please use the Check Database function then sync again. If problems persist, please force a full sync in the preferences section. I select Tools > Check Databa…

It seems to be something to do with your deck tree. Are you automating the constructions of your decks, or are you making them manually? If you upload to AnkiWeb and then answer a single card and sync again, does the problem occur?

Answering a card before syncing seems to have solved the problem. Thanks. P.S. I’m making my decks manually and wasn’t aware that another option existed.

Please note I was suggesting that as a diagnostic step - you shouldn’t need to do so each time. If you find the issue crops up again, please let me know if you spot a pattern in the steps you’re taking prior to the issue occurring.

Unfortunately, the work-around of answering a single card before syncing is no longer working. Adding a card to a new deck seems to require forcing a sync every single time. I’ve tried “check database” + answering a single card as well. This does not work. Forcing a sync seems to be the only opt…

My guess is there’s something about your deck tree that older Anki versions (and currently AnkiWeb) can’t handle, such as “parent deck” and “Parent deck::child deck” (the case should match). If you use the downgrade and quit option in the profile screen, then run Anki 2.1.26, it may spit out an erro…

Unfortunately, downgrade and quit + opening in Anki 2.1.26 did not spit out an error message. I tried diagnosing by unzipping the exported .colpkg, but it seems to be in a binary format that I am not familiar with. Sent you a private message with a link to the exported collection without media. T…

Hmm, I can’t seem to reproduce the issue - if I take the file you sent me, sync it to a test account, choosing upload, the sync is successful. If I make some small change in the program like review a card and sync again, it syncs successfully. The only difference in decks between your AnkiWeb accoun…

Hey Damien, Thanks very much for investigating this. I was able to reproduce the issue just now by adding this deck: 05: Jeff Dean (technical skills)::Operating Systems (OSes)::kernels::examples::Linux kernel::udev::foundations and then adding a single card to it. Here is a video: [2020…

I checked a backup from about a week ago, but it was using “Linux” then too. There is mention of ::udev in the error logs, which does seem to imply the parent deck is not being synced. After the usual full upload to fix it, if you add future decks one level at a time (eg, adding udev before adding u…

Did anyone solve this problem? Currently experiencing the same issue. I also have a complicated deck tree.
