Thanks
you are not alone... https://bitcointalksearch.org/topic/problem-with-upgrading-bitcoin-090-to-091-on-ubuntu-575342
I use Linux Ubunto and I don't know what to do.
Being a noob myself I asked the same question and got no answer here. Just to have it clear I was using bitcoin 0.9.0 from Ubuntu PPA and
had my libssl1.0.0 updated however in the debug window it still showed old/insecure version of OpenSSL.
So here is what I did:
-First thing first back up ur wallet.
-Shut down your client.
-Now make a backup of your current bitcoin-qt executable/shared library which should be in /usr/bin
cd /usr/bin
sudo mv bitcoin-qt bitcoin-qt.bckup
-Navigate to your Home directory
cd ~
cd Downloads
tar xvzf bitcoin-0.9.1-linux.tar.gz
cd bitcoin-0.9.1-linux
cd bin/32
/* alternatively if your system is 64 do */
cd bin/64
sudo cp bitcoin-qt /usr/bin
-start your client the usual way.
Hope it helps...
