However I cannot reproduce it. My guix-daemon is at

Hi,

I guess that means 'transferred' is #false somehow.

Looking at guix/status.scm, maybe the following is important:

string->number returns #f if the input is malformed, so I guess that

is what happens. I don't know _how_ that happens though.

Detecting #f somewhere and emitting a warning or error like

‘warning: ‘the malformed string’, representing the number of

transferred bytes, is malformed’ would be better. Fixing the underlying

error would be ideal.

I think I've seen this reported before, though I cannot find it again.

Maxime.
