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?

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 ?

    I get an error when using the second command: # sudo apt-get --allow-release-info-change update E: Command line option --allow-release-info-change is not understood in combination with the other options – Roel Van de Paar Jul 29 '18 at 21:25

    Using `sudo apt update` fixed the issue. I was prompted: "Do you want to accept these changes and continue updating from this repository? [y/N]". – Ruben O. Chiavone Oct 19 '18 at 04:26

    the `apt-get` command worked for me, with the `--allow-releaseinfo-change` _after_ the update command. – SpinUp __ A Davis Nov 12 '18 at 20:17
  • None of those options work if you invoke `apt` non-interactively (e.g. the shell does not have a controlling terminal). Even the `--yes` option is ignored without a controlling terminal. Only if you run those commands from a gnome-terminal (or xterm, or whatever terminal) do those options work. – bgoodr Nov 18 '18 at 15:34
  • it works great ! – Kamil Naja Apr 30 '19 at 19:42

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]

If you want to deploy it e.g. run in on many servers at once then execute:

apt-get update --allow-releaseinfo-change
apt-get update
apt-get install packagename

For me, anyhow, the answer was here:

https://neon.kde.org/faq#command-to-update

And I give you the link because I assume it's updated as needed. Currently, it reads that you must run:

pkcon refresh
pkcon update

Which is what I'm running. Hopefully, my computer will still work once it's done.
