Hi and thanx for a great theme!
The release key for Ubuntu 16.04 seems to have expired causing this issue for me:
W: GPG error: http://download.opensuse.org/repositories/home:/Horst3180/xUbuntu_16.04 Release: The following signatures were invalid: KEYEXPIRED 1496576244
E: The repository 'http://download.opensuse.org/repositories/home:/Horst3180/xUbuntu_16.04 Release' is not signed.
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.
Hope this requires an easy fix.
This issue is being discussed already at #793 with no response nor fix yet.
I find this issue just after pasting the commands to a friend to get the theme....what are the chances
For those that want to delete it or waiting for a fix (Ubuntu 16.04):
# remove key
sudo apt-key del BEB6D886
# remove theme source (may be different name for you)
sudo rm /etc/apt/sources.list.d/arc-theme-solid.list
@mgutz For me worked:
sudo rm /etc/apt/sources.list.d/arc-theme.list
OP: @tuxedojoe Please close this issue and we'll follow up latest updates on #793 instead.
For a quick fix for Ubuntu 16.04-18.04, please use a third-party PPA for now (FYI):
The new PPA from @fossfreedom can be added to your sources.list on Ubuntu 16.04-18.04 by
sudo add-apt-repository ppa:fossfreedom/arc-gtk-theme-daily
sudo apt-get update
Alternatively, you add the following line(s) to your sources file:
deb http://ppa.launchpad.net/fossfreedom/arc-gtk-theme-daily/ubuntu YOUR_UBUNTU_VERSION_HERE main
deb-src http://ppa.launchpad.net/fossfreedom/arc-gtk-theme-daily/ubuntu YOUR_UBUNTU_VERSION_HERE main
Install the theme package by sudo apt install arc-theme.
The PPA corresponds to @NicoHood's soft-fork. Tested on Ubuntu 16.04 and everything works! I have purged the OBS PPA source completely. No complaints about key expiring anymore :)
Thanks i2000s! I'll close it.
