You should omit these commands:

curl https://bintray.com/user/downloadSubjectPublicKey?username=decentfoundation | sudo apt-key add -
sudo add-apt-repository "deb [arch=amd64] https://dl.bintray.com/decentfoundation/$(lsb_release -is | tr "[:upper:]" "[:lower:]") $(lsb_release -cs) libpbc"

and run the third without libpbc-dev.
sudo apt-get install build-essential make cmake g++ doxygen git libreadline-dev libcrypto++-dev libgmp-dev libssl-dev libcurl4-openssl-dev libboost-all-dev zlib1g-dev

Then install
sudo apt-get install bison flex m4

Lastly install PBC unsing this link https://www.programmersought.com/article/70963054062/

after this you should be able to install dcore following from

mkdir ~/dev

Thanks for that detailed approach!

Basically, get a new pubkey, add new repo, build without libpbc-dev, install latest libpc.

Isn't that some reason insecure practice?
