well, shit

Can you help me where I fucked up? I'm not very techy. What I did is the following:
On Kubuntu:
sudo apt-get update;
sudo apt-get install git;
mkdir -p certurium-source && cd certurium-source
git clone https://github.com/certurium/certurium.git;
sudo apt-get install build-essential libtool autotools-dev automake pkg-config libssl-dev libevent-dev bsdmainutils python3;
sudo apt-get install libboost-all-dev;
wget http://download.oracle.com/berkeley-db/db-4.8.30.NC.tar.gz;
echo '12edc0df75bf9abd7f82f821795bcee50f42cb2e5f76a6a281b85732798364ef db-4.8.30.NC.tar.gz' | sha256sum -c;
tar -xvf db-4.8.30.NC.tar.gz;
cd db-4.8.30.NC/build_unix;
mkdir -p build;
BDB_PREFIX=$(pwd)/build;
../dist/configure --disable-shared --enable-cxx --with-pic --prefix=$BDB_PREFIX;
sudo make install;
cd ../..;
sudo apt-get install libminiupnpc-dev;
sudo apt-get install libzmq3-dev;
sudo apt-get install libqt5gui5 libqt5core5a libqt5dbus5 qttools5-dev qttools5-dev-tools libprotobuf-dev protobuf-compiler;
sudo apt-get install libqrencode-dev;
cd certurium;
git checkout tags/v0.19.1.1;
./autogen.sh;
./configure CPPFLAGS="-I${BDB_PREFIX}/include/ -O2" LDFLAGS="-L${BDB_PREFIX}/lib/" --with-gui --disable-shared;
make;
sudo make install;
bitcoin-qt
Afterwards it starts syncing and finishes pretty fast (around 150MB), when I create a new receive address it generates addresses starting with PC1......

The bitcoin-qt information window shows Client version v0.19.1.1, User Agend /Certurium:0.19.1/, Berkeley DB 4.8.30. Also the current block number matches with the one on chainz.cryptoID.info/crt.
Soo... Why is it generating wrong addresses

Thanks

Is there an Electrum wallet avaiable for CRT?
I have finally (I guess) set up the node myself but I get an address starting with P, whereas other addresses according to the block explorer start with A or a 3. Is the P adress legit?
There is currently no electrum wallet for CRT. Also, addresses generated in the new CRT node will always be generated with a "3" prefix. The "A" addresses are addresses from before the hardfork. An address starting with a "P" can thus not be correct.

all the best
