Some random files are not synced and there are errors related to each such file, e.g. Unexpected error doing DownloadGDBlob: .xinitrc: Mismatched checksum. I’ve tried to solve this by erasing all synced files from my computer and syncing again. This does not help as then some other random files will not sync and I see the same errors. Under Syncing… these files are shown as being synced but nothing happens.
In my case this problem might have had something to do with syncing directories to custom locations. Previously, I had synced several directories simultaneously. I again installed Insync and synced everything from scratch, only this time I selected a location for new directory only when previous one had finished syncing. These errors have now disappeared.
At some point I restored something from Google Drive trash while Insync was syncing and it replaced some files it was syncing with these restored files. It seems like you shouldn’t make any changes when Insync is doing it’s thing and only let it do one thing at a time.
I have noticed that if I don’t sync continuously and if I do some changes in some synced files, Insync will try to download the old GDrive version to my location instead to upload the current local file to GDrive.
This might be related to base folder not being present. Since I don’t sync anything to base folder I removed it and soon noticed that these errors started appearing. After restoring base folder and restarting Insync, the errors disappeared.
