Explicitly accept change for PPA 'Label'

When I run apt-get update on my ubuntu 17.10 I receive the following error:

E: Repository 'http://ppa.launchpad.net/ondrej/php/ubuntu artful InRelease' changed its 'Label' value from '*****
The main PPA for PHP (5.6, 7.0, 7.1) with many PECL extensions *****' to '*****
The main PPA for supported PHP versions with many PECL extensions *****'
N: This must be accepted explicitly before updates for this repository can be applied.
See apt-secure(8) manpage for details."

The man page doesn't really point to a solution. My question is, how do I explicitly accept the change?

Solution 1:

It would help if you posted your repositories, but, with that said, you sort of have 2 ways to fix this.

First would be to use apt rather than apt-get. apt is preferred over apt-get for interactive use in recent Ubuntu versions; and apt should, in theory, fix this for you.

sudo apt update
sudo apt upgrade

Your second option is to use --allow-releaseinfo-change

sudo apt-get update --allow-releaseinfo-change

If those options do not resolve the issue, please post your repositories, are you using mixed repositories or pinning, and, finally, tell us, is this an upgrade ?

Solution 2:

You need to use apt instead of apt-get. It will ask you to accept the changes interactively. Simply run:

sudo apt update

It should ask you:

Do you want to accept these changes and continue updating from this repository? [y/N]
