Ubuntu 18.10 Dependency release problem?

hello,
I would love to install OF on linux 18.10 ubuntu
While compiling the script for linux i got this message.
‘Err:10 http://ppa.launchpad.net/gwibber-daily/ppa/ubuntu bionic Release
404 Not Found [IP: 91.189.95.83 80]’
is it not possible for linux 18.10 to install, sorry i am very new on linux and OF.
thank you very much!

completely it says this:
E: The repository ‘http://ppa.launchpad.net/gwibber-daily/ppa/ubuntu bionic Release’ does not have a Release file.
N: Updating from such a repository can’t be done securely, and is therefore disabled by default.
