Linux Dropbox Certificate error

[GNiX]

After installing dropbox proprietary (using dropbox_2020.03.04_amd64.deb) and python3-gpg on on Linux Mint the app fails with the following message. This means Dropbox doesn't work at all on Linux when installing from the .deb file.

# dropbox start -i

Hi @GNiX,

All posted by you are warnings/deprecation messages. Unfortunately, since Linux is NOT first class citizen on Dropbox 'opinion', very often upcoming changes lag in time (sometimes actual actions start after really application stops working completely). Since by now posted by you are only warnings, they can't be a reason for "Dropbox doesn't work" (not yet, at least). If you can't still run Dropbox, download the daemon by hands (the only thing ssl-certificates are needed for). Clear the daemon's dirs (if any) using following command:

rm -rf ~/.dropbox*

 ... and install it anew with:

cd ~ && wget -O - "https://www.dropbox.com/download?plat=lnx.x86_64" | tar xzf -

Now you should be able run Dropbox either from your GUI menu or command:

dropbox start

Current status (including is application working) can be check with:

dropbox status

 Good luck.

Actually it was some issue with validating the Dropbox certificate (wget didn't work either). Re-installing ca-certificates and then reinstalling dropbox did the trick. If anyone else run in to the same problem here is what solved it for me:

sudo apt install --reinstall ca-certificates
sudo update-ca-certificates -f

Hi can someone talk me through steps to resolve this? We have already reinstalled Dropbox but this hasn't worked. 

What do I need to do to resolve these?

sudo apt install --reinstall ca-certificates
sudo update-ca-certificates -f

Thank you

Hi @caroline9, let's jump right into this!

In regards to this error, do you think that you could try running both commands, and let us know if you come across any errors? 

Keep me posted, and we'll take it from there!
