Installing Chromium Browser in Fedora 23

If you want to get the full multilib tree with signed packages (notably for libusbx.i686 and libusbx.x86_64), go to https://repos.fedorapeople.org/repos/spot/chromium/ and use that repository instead.

Use this command to create a repos:
sudo gedit  /etc/yum.repos.d/fedora-chromium-stable.repo

# Place this file in your /etc/yum.repos.d/ directory

[fedora-chromium-stable]
name=Builds of the "stable" tag of the Chromium Web Browser
baseurl=https://repos.fedorapeople.org/repos/spot/chromium-stable/fedora-$releasever/$basearch/
enabled=1
skip_if_unavailable=1
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/spot.gpg

[fedora-chromium-stable-source]
name=Builds of the "stable" tag of the Chromium Web Browser - Source
baseurl=https://repos.fedorapeople.org/repos/spot/chromium-stable/fedora-$releasever/SRPMS
enabled=0
skip_if_unavailable=1
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/spot.gpg

For some reason, I keep getting an gpg error:

warning: /var/cache/dnf/fedora-chromium-stable-fae8399dc26ced2e/packages/chromium-46.0.2490.80-1.fc23.x86_64.rpm: Header V4 DSA/SHA1 Signature, key ID 93054260: NOKEY
Curl error (37): Couldn't read a file:// file for file:///etc/pki/rpm-gpg/spot.gpg [Couldn't open file /etc/pki/rpm-gpg/spot.gpg]
The downloaded packages were saved in cache till the next successful transaction.

I run this command:

sudo rpm --import http://repos.fedorapeople.org/repos/spot/chromium-stable/spot.gpg

After running the above command , try reinstall Chromium again:

sudo dnf install chromium

Voila. Good Luck
