How you can help?

Try these commands:

sudo aptitude install distributed-net
dnetc

and please report if it working. Do not forget to mention are you using AMD64 or 32-bit version of Ubuntu.

They seem to have similar bug with sparc + debian.

Filed bug in the distributed.net bugtracker:

And found one in the Debian BTS:

Seems to be amd64 compiler incompatibility issue, due to dnetc is shipped as a binary. Workaround is to remove libnss-mdns package if you don't need it.

sudo aptitude remove libnss-mdns

[Eugene (varnav)]

Confirmed in upstream

[Thomas Zehetbauer (realborg)]

Same problem here. Purged libnss-mdns and everything suddenly started working. What is libnss-mdns good for anyway?
