Ubuntu Full Node Error: X509 Certificate Signed By Unknown Authority

I've been trying to setup a Full node on Ubuntu 14.

When running the command:
./dcrctl -u username -P password --wallet getnewaddress

It says:
Post https://localhost:9110: x509: certificate signed by unknown authority

In another terminal window I have the following command running:
./dcrwallet --username username --password password --dcrdusername=username2 --dcrdpassword=password2

In the monitor window it states the following in the log:
2016/05/18 11:51:36 http: TLS handshake error from 127.0.0.1:47105: remote error: bad certificate

To fix the issue I have attempted to try the following:
sudo -i
cp /home/user/.dcrd/rpc.cert /usr/share/ca-certificates/dcrd.crt
echo dcrd.crt >> /etc/ca-certificates.conf
update-ca-certificates
exit

But still did not help.

Thank you in advance.

 

I have also attempted the following but no lock:
sudo -i
cp /home/user/.dcrwallet/rpc.cert /usr/share/ca-certificates/dcrwallet.crt
echo dcrwallet.crt >> /etc/ca-certificates.conf
update-ca-certificates
exit

 

Even executing the command
./dcrctl -u password2 -P password2 --wallet walletpassphrase password 0

produces the same error messages above.

 

Finally fixed the issue:

I needed to ttell dcrctl where the cert file was so I ran the following:
./dcrctl -u username -P password --wallet getnewaddress --rpccert=/home/user/.dcrd/rpc.cert

hope it helps everyone else
