Deja-Dup Backup Failed Ubuntu 19.04

[saywot]

I haven't been able to complete a back-up for weeks
I'm trying to use a formatted external HDD and the outout from the failure window is, to me, incomprehensible
the Failed Due To An Unknown Error has this in a window

What am I supposed to make of that ?

So I uninstalled then re-installed tried a back-up to the same location, with the "snap' version I get
Back-Up Failed
Failed to read /tmp/duplicity-vc74him5-tempdir/mktemp-dafhu7iq-2: (<class 'OSError'>, OSError('CRC check failed 0x940ae478 != 0x84d0fc3f',), <traceback object at 0x7fef723e9048>)

This bug is the closes I've found on it: https://bugs.launchpad.net/deja-dup/+bug/676767

The comments show that removing the cache for it can help.

For the third time

Failed to read /tmp/duplicity-yq19nvma-tempdir/mktemp-hm_o6lg0-2: (<class 'OSError'>, OSError('CRC check failed 0x940ae478 != 0x84d0fc3f',), <traceback object at 0x7f05d4723148>)

I think we can say that Deja-Dup is never going to create a back-up

[saywot]

Deleted .cache/Deja-Dup twice and ...
Failed to read /tmp/duplicity-rs9mzb5u-tempdir/mktemp-zn6aj1xn-2: (<class 'OSError'>, OSError('CRC check failed 0x940ae478 != 0x84d0fc3f',), <traceback object at 0x7f4eb0a730c8>)
so what else can I try ?

[saywot]

If deleting the cache doesn't work then what else can I try ?

[saywot]

sudo deja-dup
[sudo] password for saywot: *************

Does this mean anything ?

It's a bit of an oblique response, but are you wedded to using deja-dup? Other backup solutions are available.

I recall having issues with it years ago. I switched to back in time and have had no problems.
