尝试下使用下面的命令去创建快照，然后把报错贴一下，我记得这个好像是mount失败了，内部已修复，可能还没对外推新版本吧

这是一个内部还没发现的bug，针对于从之前的版本升级上来的用户会有这种问题，已经定位到原因，本周内部就可以修复，需要等下个版本推送，更新deepin-immutable-ctl(> 0.0.33)这个包再尝试创建快照

前面发的确实是从deepin25preview通过控制中心升级到alpha的。

我这另一个全新安装alpha的设备（安装好后进行过一次控制中心升级），也是备份失败的。

日志输出超过了万行，最后几行内容是这样：

我先反馈下内部测试同学吧，看能否复现出来，这个情况确实没见到过，需要出现后再分析下原因

刚用命令更新了一下V25 ALPHA系统，在UI界面创建备份还是到98%失败，和更新前一样。原来是等待4分钟失败，现在要等到6分钟失败，不知道什么原因。

已经定位到原因，是Alpha系统中存在的bug，在新版本中已修复，需要等下个版本推送更新deepin-immutable-ctl这个包

问题描述

deepin25Alpha备份失败

复现步骤

1. 全盘安装deepin25Alpha
2. 安装完成进入系统后，通过控制中心更新至Alpha最新
3. 更新完成重启后，打开终端，手动执行命令进行系统备份并记录日志，命令如下：

sudo sh -c 'DDE_DEBUG_LEVEL=debug deepin-immutable-ctl snapshot create "test-name" "test-desc" -wv > immut_backup.log 2>&1'

日志文件

一万五千余行：immut_backup.txt

截图/录屏

略

补充信息

deepin-immutable-ctl：0.0.31.5

稍微不一样的地方是，我曾用自己编写的脚本为系统级目录写入过一些文件（这些文件在原系统中并不存在），不确定这一行为是否有影响，如：

/etc/vim/vimrc.local
/usr/local/bin/xxx（私人脚本）
/etc/X11/xorg.conf.d/50-Miix4-FolioTouch.conf（用于开启触摸板右键滚动）
/etc/X11/xorg.conf.d/60-Miix4-ElanTouchscreen.conf（用于屏蔽半坏的触摸屏）

这些文件是不影响的

问题我们内部已解决，要等推送，和8楼回复的问题原因是一样的

和挂载相关的问题，我们内部也是修复了的，也要等推送

方便说一下deepin-immutable-ctl的版本么以及你的系统的分区情况吗，我好确认是否这个修复对你有效

使用apt policy deepin-immutable-ctl和findmnt去查看

确实修复了，你先尝试更新deepin-immutable-ctl 到0.0.31.5版本，我记得这个版本就是修了的

后续我们自己还优化了这块流程，能更好的处理挂载的情况，会在后面推送

如果还是不行，有一个手动操作的方式可以临时解决

sudo mount -o remount,rw /sysroot/ostree

然后再执行之前的命令就可以了，不过重启会恢复
