Updating Bitcoin Core

[topkurs]

Hello, guys!
I have installed Bitcoind + RPC-JSON
version is 0.12.1

Now I want to update Bitcoind to up-to-date 0.15.0.1.

I have Debian 8.9 (jessie)
I have updated it through repositories, because don't want to delete-download and kill all previous configs.

First of all I have loaded /etc/apt/sources.list with unstable sources - https://packages.debian.org/sid/bitcoind. Because bitcoind is available only as sid(unstable):

# Unstable
deb http://ftp.debian.org/debian unstable main contrib non-free
deb-src http://ftp.debian.org/debian unstable main contrib non-free

Than installed

apt-get install bitcoind/unstable

Seems, everything is installed

But now I have strange situation. Bitcoind is seems 0.15.0.1

# apt-cache policy bitcoind
bitcoind:
  Installed: 0.15.0.1~dfsg-1
  Candidate: 0.15.0.1~dfsg-1
  Version table:
 *** 0.15.0.1~dfsg-1 0
        500 http://ftp.debian.org/debian/ unstable/main amd64 Packages
        100 /var/lib/dpkg/status

# apt-cache show bitcoind
Package: bitcoind
Source: bitcoin
Version: 0.15.0.1~dfsg-1
Installed-Size: 5823

But real version is:

# bitcoin-cli getinfo
  'version' => 120100,
  'protocolversion' => 70012,
  'walletversion' => 60000,
  'balance' =>***,
  'blocks' => 492091,
  'timeoffset' => 0,
  'connections' => 11,
  'proxy' => '',
  'difficulty' => 1452839779145.9189,
  'testnet' => false,
  'paytxfee' => 0,
  'relayfee' => 1.0000000000000001E-5,
  'errors' => 'Warning: unknown new rules activated (versionbit 1)',
)

Why is it so?
How to fix all this? How to update correctly to 0.15.0.1 ?

Could it be you now have 2 versions installed on different locations, with the oldest first in the default path?

Try:

Code:

bitcoin-cli --version
bitcoind --version

Or:

Code:

pwd bitcoin-cli
pwd bitcoind
