Just to start, uname -a results: Linux fedorabox 4.8.8-200.fc24.x86_64+debug #1 SMP Tue Nov 15 19:14:59 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux

I tried to upgrade to Fedora 25 using software app, clicked on download and waited for process to complete. At the end of it I got a dialog box with the following:
Running transaction check
Transaction check succeeded.
Running transaction test
The downloaded packages were saved in cache until the next successful transaction.
You can remove cached packages by executing 'dnf clean packages'.
Error: Transaction check error:

I tried this from the command line as root and got these results:
[root@fedorabox gelam]# dnf system-upgrade download --releasever=25

I then tried this from the command line, and the package listed as errors are somewhat different every time:

Any help will be appreciated

So do the cleanups flagged, and in the link posted.

FWIW, I tend to wait 4-6 weeks so (hopefully) all the wrinkles have been ironed out.

I have never ever liked upgrades.

Checksum is a problem here too. Yes, could be poor upgrade paths. Could be bad source, get a different source or get full dvd and test locally?
