I'm getting the same issue. Changing the URLs to https://maemo-repos.com/ rather than http://maemo-repos.com/ yields errors. I'm thinking it could be certificate related. Code: curl --capath /etc/certs/common-ca/ -v https://maemo-repos.com/ Works fine, so the cert seems to be OK, unless dpkg uses some other CA path... Ideas welcome!
curl --capath /etc/certs/common-ca/ -v https://maemo-repos.com/
