Ошибка с обновлением sudo apt-get

Я получаю следующую ошибку при попытке sudo apt-get update

E: The repository "http://ppa.launchpad.net/grumbel/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.. 
N: See apt-secure(8) manpage for repository creation and user configuration details.  
N: Loading the configured file "main/binary-i386/Packages" is skipped because the repository "http://dl.google.com/linux/earth/deb stable InRelease" does not support the architecture "i386". 
E: For the "http://ppa.launchpad.net/webupd8team/java/ubuntu bionic InRelease" repository, the "Label" value has been changed from "Oracle Java (JDK) 8 Installer PPA" to "Oracle Java (JDK) 8 Installer PPA (DISCONTINUED)". 
N: This must be accepted explicitly before updates for this repository can be applied. 
See apt-secure(8) manpage for details..
