You must use fedup 0.8 to upgrade to Fedora 20（升级到Fedora

I failed to upgrade Fedora 19 to Fedora 20 directly by running fedup sudo fedup--network20, you must do this firstly, following vbraun‘s advice.
sudo yum --enablerepo=updates-testing update fedup
If you have failed with fedup 0.7, you can do this to avoid redownload packages, following AdamW‘s advice.
sudo mv /var/lib/fedora-upgrade /var/lib/system-upgrade
sudo mv /var/tmp/fedora-upgrade /var/tmp/system-upgrade
And then, import GPG-KEY, following Sayen‘s advice:
sudo rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY-rpmfusion-nonfree-fedora-20
Finally，
sudo fedup --network 20
--------------------------------------------------------------------------------
For my case, before importing GPG KEY, error occured again:
...
warning: /var/tmp/system-upgrade/rpmfusion-nonfree/packages/rpmfusion-nonfree-release-20-1.noarch.rpm: Header V3 RSA/SHA256 Signature, key ID b5f29883: NOKEY
Importing GPG key 0xB5F29883:
Userid : "RPM Fusion nonfree repository for Fedora (20) <[email protected]>"
Fingerprint: a84d cf58 46cb 10b6 5c47 6c35 63c0 de8c b5f2 9883
Package : rpmfusion-nonfree-release-19-1.noarch (installed)
From : /etc/pki/rpm-gpg/RPM-GPG-KEY-rpmfusion-nonfree-fedora-20
Downloading failed: Didn't install any key
At that moment, no one tell me a solution, so I ignored the KEY CHECK by
sudo fedup --network 20 --nogpgcheck
And, I works!!!
Sayen also adviced me to try this before run fedup. I think it better than the “–nogpgcheck solution”.
sudo rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY-rpmfusion-nonfree-fedora-20

Some others problems:

And another Perl script failed to start.

The solution is to clear the old modules, following 3rensho’s comment:
sudo rm -rf /usr/local/lib64/perl5/*
sudo rm -rf /usr/local/share/perl5/*
