   After the installation process I receive a notification

   0"Warning: The home dir /var/lib/bitcoin you specified can't be accessed: No such file or directory
   1Adding system user `bitcoin' (UID 113) ...

   5bitcoind.service is a disabled or a static unit, not starting it. "
   

   I started opening bitcoin-qt unsuccessfully

   0" sudo bitcoin-qt
   1QXcbConnection: Could not connect to display
   2Aborted (core dumped)"
   

   I’m using Ubuntu 16.04 user sudo but not root Is there any way to solve this problem?

   Cannot reproduce the issue:

   0$ bitcoin-qt -version | grep version
   1Bitcoin Core version v0.18.0.0-g2472733a24a9364e4c6233ccd04166a26a68cc65 (64-bit)
   

   @WalletCat Could you provide your output of bitcoin-qt -version | grep version?

    @WalletCat The ppa is unmaintained (at least for now). You might want to try the Bitcoin Core snap or flatpak:

    " sudo bitcoin-qt

    also it’s a bad idea to run a X program with sudo, I don’t think it passes through the DISPLAY and such, also there is no reason why you’d run bitcoind or -qt as root
