当我尝试从jaunty升级到karmic时,我遇到了这个问题：
root@server:~# sudo do-release-upgrade Checking for a new ubuntu release Done Upgrade tool signature Done Upgrade tool Done downloading extracting 'lucid.tar.gz' authenticate 'lucid.tar.gz' against 'lucid.tar.gz.gpg' tar: Removing leading `/' from member names Reading cache Checking package manager Can not upgrade An upgrade from 'jaunty' to 'lucid' is not supported with this tool.
当我需要先升级到业力时,我不知道为什么它会尝试升级到清醒.我想它从某个地方得到了“清醒”这个词,但我不知道从哪里开始寻找.
解决了它.原来,/ etc / update-manager / Meta-release指向
http://changelogs.ubuntu.com/meta-release,该文件说：
dist: karmic Name: Karmic Koala Version: 9.10 Date: Thu,29 Oct 2009 12:00:00 UTC Supported: 0 Description: This is the 9.10 release Release-File: http://archive.ubuntu.com/ubuntu/dists/karmic/Release ReleaseNotes: http://changelogs.ubuntu.com/EOLReleaseAnnouncement Upgradetool: http://archive.ubuntu.com/ubuntu/dists/karmic-proposed/main/dist-upgrader-all/0.126.9/karmic.tar.gz UpgradetoolSignature: http://archive.ubuntu.com/ubuntu/dists/karmic-proposed/main/dist-upgrader-all/0.126.9/karmic.tar.gz.gpg
我下载了文件,将“Supported：0”更改为“Supported：1”并将文件托管在我自己的网络服务器上,并将元文件指向我的服务器.工作得很好.
