Lightroom Classic CC stuck syncing 1 photo, have tried Rebuild Sync Data

For months my Lightroom Classic CC desktop has been stuck syncing 1 photo, but I didn't bother troubleshooting. I recently uploaded a lot of content to Lightroom mobile while I was away for some weeks, when I got home it was now stuck syncing a couple hundred photos. I tried the "Rebuild Sync Data" suggested in some forums, and it cleared away the couple hundred photos, save and except for one single photo (the same offending one or a different one, not sure). I have tried "Rebuild Sync Data" multiple times (and, of course, restarting my system entirely), but still it remains stuck syncing one photo... help?

OS 10.13.6 // Lightroom Classic CC 7.5

Correct answer john beardsworth

hum, seems to be quite a mess. At this point, not sure how to identify the offending photo, as there seem to be thousands of sync errors overall... At least Web and Mobile seem to have the same number for "all photos"

see details below, help???

Lightroom Classic CC desktop >> 21,418 synced photos + 4,257 sync errors

Lightroom mobile on my iPhone >> 25942 photos

Lightoom Web >> 25942 photos + 234 sync errors


But this is a wholly-different order of magnitude than your initial post. I don't think you're going to solve it as easily as with one problem image, and I am probably going to recommend the Preferences / LRCC / Delete All Data route, but let's proceed slowly - don't zap the mobile data yet.

Your synced images. Where exactly do they originate? Are all of them images that you have synced from Classic? If that is the case, you could use Delete All Data and resync them. But it's more likely that the synced images are a mix of stuff synced from Classic, and stuff imported into LRCC. So before we zap the mobile data, please say where the synced images originate. Are many of them iPhone photos? If so, are they photos taken with LrMobile, or were they taken with the iPhone camera and imported? Have images got into Sync from some other source?

Hi Andrewklug,

Sorry that you have 1 image stuck in the Lightroom(Classic CC 7.5) sync activity menu and doesn't syncs to the cloud despite rebuilding the sync data and deleting many images.

Could you please Log into Lightroom Web (Photo Editor | Online Photoshop Lightroom ) and check if that 1 image still hanging around? If so, delete it and then rebuild the sync data and let us know how it goes.

Thanks,

Akash

Hello Akash

Apologize for any misunderstanding, to clarify, I did not delete any images, I simply rebuilt the sync data and the thing got almost cleared up, but still stuck at "syncing 1 photo"... I don't know if it's the same offending photo, or a different one.

Now it gets even more strange... if I look under Sync Activity in the Preferences window, I see a large number of files uploading and downloading, but one error at the bottom. So I click on that and it brings me to the image, I change the image rating but now it's showing me errors on different files, so it seems like it's just getting worse and I have no idea why these files are giving error, they are files I haven't touched in a long time

As you've understood, "upwards" errors don't really matter. Also I do not trust the sync errors reported in LrWeb because this item reports other stuff too - eg where one confuses sync by renaming a photo while it was syncing upwards, or where Adobe's servers haven't been able to read some image data.

So I think we're at the point where I said earlier "If there is a risk of 'the rest' not being backed up, I'd suggest you run the Lightroom Downloader to download everything that is on the server." Read that paragraph again, especially about installation/uninstallation, and run a download. It will grab everything that's up there, including smart previews as well as originals. You should be able to easily distinguish them, eg by importing the download folder into a new LR catalogue. Then copy any originals that failed to sync downwards and paste them into your normal folder structure. That seems the best next step.


OK, makes sense, thank you very much. That being said, given the volume of images here, using the Lr Downloader begs the question of how to identify among the content downloaded from the server any originals that never "made it down" from Lr mobile thru sync... as this would involve parsing all 25,942 originals dowloaded via the Downloader, and comparing them one by one against my Lr Classic CC library to see which, if any, were missing because they never "made it down" via sync.

Also I do not trust the sync errors reported in LrWeb because this item reports other stuff too - eg where one confuses sync by renaming a photo while it was syncing upwards, or where Adobe's servers haven't been able to read some image data.

>> to the extent the only error that concerns me is an original that never "made it down" from mobile to Classic CC library via sync, are you suggesting here that the 234 sync errors identified above with respect to Lr Web OVERSTATES the number of potential "didn't make it down" errors? Could I not parse these 234 sync errors on Lr Web, see if there's anything I'm missing and grab it from there manually as the case may be, and otherwise proceed to nuke the server?

Thanks again...
