[MM3-users] Archive download - unexpected end of file

Hi,

I have a MM3 list to whose archive I recently added an mbox file of older emails.

Viewing/searching the archive (Hyperkitty) is working fine.

Downloading archives "for the month" or "last 30 days" delivers the expected ".mbox.gz" file and those are fine.

However, when I download the "Entire archive" and attempt to gunzip that ".mbox.gz" file I get the error: " ... unexpected end of file".

Or using Gnome desktop's "Extract", I get the error "..truncated gzip input"

Any tips on resolving this would be gratefully received.

Best, Mark
