opkg can't update in om2008.8?

[Dietz Proepper]

Hi,

"opkg update" on my freshly flashed om 2008.8 seems to
be unable to get new packages. The download works ok but then
it says "Failed to download etc.":

(the following trimmed to output from one archive only)

root at om-gta02:/etc/opkg# opkg update

Any idea?

kindest regards,
