updated to Hera and consistently get this error code for every attempted install via app center. What is the solution for this issue?

E: The repository 'http://packages.elementary.io/appcenter hera Release' does not have a Release file. W: Updating from such a repository can't be done securely, and is therefore disabled by default. W: See apt-secure(8) manpage for repository creation and user configuration details.


You need to change the sourcelist. Open the terminal and type;

sudo nano '/etc/apt/sources.list.d/appcenter.list'

replace all the hera with bionic

Save: [ctrl]+[o] Exit: [ctrl]+[x]


sudo apt update

You might as well check rest of your sourcelists;

sudo nano '/etc/apt/sources.list'
