Dropbox not uploading/syncing new files after fresh install of Linux Mint 20.1

Hi Walter , Здравко , Jay , Hannah ,

For the sake of completeness I just wanted to post a note here that this issue is resolved and what the problem was.

After some initial troubleshooting and repeating another remove and reinstall without resolution, tech support had me enter the following commands:

sudo chown "$USER" "$HOME"
 
sudo chown -R "$USER" "/home/joe/Dropbox" ~/.dropbox
 
sudo chattr -R -i "/home/joe/Dropbox"
 
sudo chmod -R u+rw "/home/joe/Dropbox" ~/.dropbox

I saw after entering the *chattr* command that I received pages of errors regarding a Timeshift backup folder I'd previously copied into Dropbox (thinking if I ran into problems later in my upgrading and had to do a fresh reinstall of the OS, I could copy the folder back to its original path to restore from). In hindsight a bad idea, but I didn't give it a thought when the Dropbox issue cropped up later.

So once I removed the Timeshift folder from Dropbox, I re-ran the above commands without any errors, and Dropbox subsequently synced properly.

(I guess there is still an open question about the python script, as I tried to run the testdropbox script file again and still got the error, but since that's not causing me current problems, I'll let it slide for now.)

Thank you all again,

Joe
