do-release-upgrade升级没成功用debootstrap重装升级成功
说明有三个系统FreeBSD宿主机FreeBSD jail子系统 Ubuntu jail 子系统
安装好后可以从宿主机进入FreeBSD或Ubuntu jail子系统。在FreeBSD jail子系统里可以安装多个Ubuntu jail子系统并进入该子系统。
Ubuntu jail子系统里升级focal到jammy
使用do-release-upgrade升级失败
参考Install Ubuntu 22.04 Jammy in FreeBSD Jail | The FreeBSD Forums
在FreeBSD宿主机进入Ubuntu jail 子系统使用命令
jexec focal_to_jammy chroot /compat/ubuntu /bin/bash子系统是以前克隆的focal版本依次执行升级命令
apt install update-manager-core
do-release-upgrade -d
没升级成功。
用-d选项的话没有错误信息去掉-d选项有报错信息见后面调试部分。最终没有用这种方法升级成功。
使用debootstrap升级
使用cbsd jlogin focal_to_jammy 进入FreeBSD jail子系统这时候是处于FreeBSD系统下有pkg指令所以
先pkg安装debootstrap
pkg install debootstrap 执行debootstrap 下载jammy
debootstrap jammy /compat/jammy 这样FreeBSD jail子系统里的操作就结束了后面就是进入jammy jail子系统进行操作了。
进入jammy jail子系统
从FreeBSD jail子系统执行chroot进入jammy子系统
focal_to_jammy:/root[9:37] # chroot /compat/jammy/ /bin/bash
groups: cannot find name for group ID 0
groups: cannot find name for group ID 5
I have no name!focal_to_jammy:/# 如果顺利到了这一步就可以结束了但是
发现这个jammy子系统里又没有apt
怎么老碰到这个问题
debootstrap安装jammy时的输出有apt这个包啊
I: Retrieving apt 2.4.5 I: Validating apt 2.4.5
I: Extracting base-files... I: Extracting base-passwd... I: Extracting bash... 发现确实没有解开apt的包
第二次使用--includeapt选项
debootstrap --includeapt jammy /compat/jammy I: Validating adduser 3.118ubuntu5 I: Validating apt 2.4.5 I: Validating apt-utils 2.4.5
还是没有Extracting解开apt 包。话说debootstrap就这么节俭吗 连个apt包都不给 还是说只有FreeBSD下的这个debootstrap不给
看看jammy里的/usr/bin 目录里面就是没有apt
jammy jail子系统里手工安装apt
以前手工安装apt会碰到依赖库的问题操作很繁琐这回找到了一个最方便的方法
dpkg --force-depends -Ei /var/cache/apt/archives/*.deb jammy jail子系统里所有的deb包放在/var/cache/apt/archives目录
只要使用这一条命令就能装好apt包使用命令
dpkg --force-depends -Ei /var/cache/apt/archives/*.deb
过程中问到键盘设置啥的 还有pam的配置改变要不要覆盖 One or more of the files │ │ /etc/pam.d/common-{auth,account,password,session} have been locally │ │ modified. Please indicate whether these local changes should be │ │ overridden using the system-provided configuration. If you decline this │ │ option, you will need to manage your systems authentication │ │ configuration by hand. │ │ │ │ Override local changes to /etc/pam.d/common-*? │ │ │ │ Yes No
因为是新系统本地没啥所以选择了Yes覆盖
后面还有设置时区shanghai 等
安装完成后终于有了APT
但是刚开始使用apt会报错
apt update 报错问题解决

N: Updating from such a repository cant be done securely, and is therefore disabled by default. N: See apt-secure(8) manpage for repository creation and user configuration details. 看里面讲到 /dev/null: Permission denied就给它666权限 执行chmod 666 /dev/null
将/dev/null设为666
chmod 666 /dev/null
然后update 搞定但是upgrade报错
apt upgrade Reading package lists... Done Building dependency tree... Done You might want to run apt --fix-broken install to correct these. The following packages have unmet dependencies: dash : Depends: dpkg ( 1.19.1) but it is not installed grep : Depends: dpkg ( 1.15.4) but it is not installed or install-info but it is not installed gzip : Depends: dpkg ( 1.15.4) but it is not installed or install-info but it is not installed perl-base : PreDepends: dpkg ( 1.17.17) but it is not installed python3-minimal : Depends: dpkg ( 1.13.20) but it is not installed readline-common : Depends: dpkg ( 1.15.4) but it is not installed or install-info but it is not installed E: Unmet dependencies. Try apt --fix-broken install with no packages (or specify a solution).
尝试apt --fix-broken install修复apt upgrade报错问题
按照报错提示输入
apt --fix-broken install
修复完成apt install wget 成功
现在看看版本
lsb_release -a
lsb_release -a No LSB modules are available. Distributor ID: Ubuntu Description: Ubuntu 22.04 LTS Release: 22.04 Codename: jammy 成功升级到jammy版本 总结
本来想用下面两条执行将focal升级到jammy但是没有成功。
apt install update-manager-core
do-release-upgrade -d
最终还是使用了debootstrap 老办法升级成功。
debootstrap安装jammy
pkg install debootstrapdebootstrap jammy /compat/jammychroot /compat/jammy/ /bin/bash chmod 666 /dev/nulldpkg --force-depends -Ei /var/cache/apt/archives/*.debapt updateapt --fix-broken installapt upgrade# 看版本lsb_release -a 调试
do-release-upgrade -d提示set Promptnorma
do-release-upgrade -d Checking for a new Ubuntu release There is no development version of an LTS available. To upgrade to the latest non-LTS development release set Promptnormal in /etc/update-manager/release-upgrades.
在/etc/update-manager/release-upgrades文件里将Promptlts修改成Promptnormal
结果执行后没什么反应

问题依旧。
这样在FreeBSD的jail里想要focal升级到jammy Ubuntu的实验失败告终。
