从13.10升级到14.04:“未找到新版本”
我试图从lubuntu 13.10升级到14.04使用
apt-get update apt-get dist-upgrade do-release-upgrade
但是,最后一个命令返回No new release found
我也尝试了do-release-upgrade -d
,结果相同。
/etc/apt/sources.list
看起来像:

请注意,我刚刚使用相同的服务器升级了lubuntu而没有任何问题。
/etc/update-manager/meta-releases
文件内容
# default location for the meta-release file [METARELEASE] URI = http://changelogs.ubuntu.com/meta-release URI_LTS = http://changelogs.ubuntu.com/meta-release-lts URI_UNSTABLE_POSTFIX = -development URI_PROPOSED_POSTFIX = -proposed
/etc/update-manager/release-upgrades
看起来像:
# some comments... Prompt=normal
我也没有成功改变normal
。
我还检查了目录/var/lib/ubuntu-release-upgrader/
是否为空。
/etc/apt/apt.conf.d/
也没有proxy
文件,因此似乎没有使用代理。
/etc/hosts
文件如下所示:
127.0.0.1 localhost 127.0.1.1 mybox # The following lines are desirable for IPv6 capable hosts ::1 ip6-localhost ip6-loopback fe00::0 ip6-localnet ff00::0 ip6-mcastprefix ff02::1 ip6-allnodes ff02::2 ip6-allrouters
所以我尝试了分发升级问题“找不到新版本”的每个解决方案都没有成功。
知道这里可能有什么问题吗?
编辑
使用图形界面update-manager
我收到错误消息:“无法下载存储库信息”
也许这会给你一个如何解决问题的提示。
EDIT2
我现在从de服务器更改为主服务器,并从sources.list
和sources.list.d
删除了所有ppas。 如果可能的话使用ppa-purge
。 如果没有,我用aptitude清除了相关的包,然后删除了ppa-entries。
关于以下包裹的ppa: sagemath
, google-earth
, freetuxtv
, freetuxtv
和julia
(数学程序)。
但没有成功。
对我来说,原因是我已经禁用了自动检查升级 ,因为check-new-release
过程会大大减慢我的计算机速度。
在/etc/update-manager/release-upgrades
更改回Prompt=normal
立即修复问题。
它终于奏效了。 问题是我确实以root身份do-release-upgrade
,这没有用。 像普通用户一样调用此命令。 Hower我不明白为什么它不是root。
试试这个!!!
剪切并粘贴以下整套命令:
sudo apt-get clean ; cd /var/lib/apt ; sudo mv lists lists.old_`date '+%Y%m%d_%H%M%S'` ; sudo mkdir -p lists/partial ; sudo apt-get clean ; sudo apt-get update
分号标定每个命令,以便将它们粘贴在一起。 之后这样做:
sudo apt-get clean sudo do apt-get update sudo apt-get dist-upgrade sudo do-release-upgrade
如果失败,那么执行以下操作:
sudo sed -i 's/saucy/trusty/g' /etc/apt/sources.list sudo apt-get update sudo apt-get upgrade
注意:删除所有第三方PPA,除非他们有14.04版本可用。 如果你有Gnome PPA用PPA-Purge将其移除。
您需要选中此选项:
然后再次启动do-release-upgrade
从终端或unity启动器运行命令:gksu update-manager -d。 如果您尝试运行sudo update-manager -d,它并不总是提供14.04可用选项。 但是使用gksu,会出现此选项。
否则,请创建可启动的USB驱动器。 使用相同的引导和安装时,选择升级或其他。 在其他方面,为/,swap的挂载点提供相同的驱动器。 取消选择格式选项。 不要选择格式。 这将保留您的所有文件和以前的设置并进行升级。
谢谢。
我最近也被“发现没有发布新版本”所困扰,结果certificate这是一个连接问题。 基于此Snort / Suricata规则,我们的防火墙阻止了该请求:

我知道这不是你的问题,但希望它有助于另一个人。
