Can't update or install the Dropbox application on Fedora 43 Plasma

This worked on my laptop, where I had not uninstalled and I was just disabling the repo on the fly in dnf so that updates would work.

On my desktop, I am still getting the same result. I had not deleted the Dropbox repo. I uninstalled the flatpak, then downloaded the new rpm (2026.01.15) and installed using KDE's Discover. When I launch using Discover (or the application launcher) and it prompts me to install the daemon, I get the same message:

Trouble connecting to Dropbox servers. Maybe your internet connection is down, or you need to set your http_proxy environmental variable.

I tried rebooting and that didn't help.

When I run `dropbox status -i` I get the same result that I reported above.

When I run 'dnf list --installed | grep dropbox' or `dnf info nautilus-dropbox`, the repo for nautilus-dropbox is shown as

<unknown>

I uninstalled using `sudo dnf remove nautilus-dropbox` AND removed the repo using `sudo rm /etc/yum.repos.d/dropbox.repo`, rebooted and installing the downloaded rpm using dnf. I get the same result except that the repo for nautilus-dropbox is shown as

@commandline

AND I get the following error:

>>> Scriptlet output:

>>> error: can't create transaction lock on /usr/lib/sysimage/rpm/.rpm.lock (Resource temporarily unavailable)

>>> error: -: key 1 import failed.
