CentOS 6.5から7系へのアップグレード中のDownloading failedの対処法


アップグレード方法はこちらを参考にした
CentOS 6.5から7.2にアップデートした時のメモ
英文だがこちらはさらに詳しい

問題はここ
# centos-upgrade-tool-cli
--force --network 7 --instrepo=http://mirror.centos.org/centos/7/os/x86_64
setting up repos...
getting boot images...

Downloading failed: invalid data in .treeinfo: No option 'upgrade' in section: 'images-x86_64'
.treeinfoを見てみると、たしかにupgradeがない。

ここはinstrepoをvault.centos.orgに変更するとよいらしい
参考: 远程升级云服务器系统 CentOS 6.x 至 CentOS 7.x
下記の指定だと7.2.1511が入る。
# centos-upgrade-tool-cli --force --network 7 --instrepo=http://vault.centos.org/centos/7.2.1511/os/x86_64/
setting up repos...
getting boot images...
setting up update...
 自己責任で。
