对我有用的解决方案

Question 1

我正在运行 16.04 LTS，遇到了完全相同的问题，但我采用了不同的方法。

删除Redmine

我没有删除dpkg脚本，而是打开脚本redmine.postrm并注释掉导致删除后脚本崩溃的行，所以我的文件变成如下形式：

$ cat /var/lib/dpkg/info/redmine.postrm
#!/bin/sh

set -e

. /usr/share/debconf/confmodule
if [ -f /usr/share/dbconfig-common/dpkg/postrm ]; then
  . /usr/share/dbconfig-common/dpkg/postrm

  # remove both current and old instances
# START OF THE COMMENTED SECTION TO AVOID CRASHES 
#  instances=$(ls -1 /etc/redmine/*/database.yml | xargs dirname | xargs -n 1 basename)
#  for inst in $instances; do
#    dbc_go redmine/instances/$inst "$@"
#  done
# END OF THE COMMENTED SECTION TO AVOID CRASHES
fi

if [ "$1" = purge ]; then
  rm -rf /var/log/redmine
  rm -rf /var/cache/redmine
  rm -rf /var/lib/redmine
  rm -rf /etc/redmine
fi

## Automatically added by dh_installdebconf
if [ "$1" = purge ] && [ -e /usr/share/debconf/confmodule ]; then
    . /usr/share/debconf/confmodule
    db_purge
fi
# End automatically added section
#

这让我可以简单地用以下方法删除它：

sudo apt-get remove redmine --purge

它会提示您是否要删除数据库redmine_default；我回答是的，但您应该谨慎选择。

此后，它将在没有任何警告的情况下清除您的所有安装，因此您的第一个问题已经得到回答。

重新安装Redmine

现在，如何安装 redmine 并使其运行？

我们首先要做的是

sudo apt-get update && sudo apt-get install redmine redmine-mysql

它可能会再次崩溃，并出现类似以下的情况：

Configurando redmine (3.2.1-2) ...
Determining localhost credentials from /etc/mysql/debian.cnf: succeeded.
dbconfig-common: writing config to /etc/dbconfig-common/redmine/instances/default.conf

重新创建 database.yml

其中明确指出

Could not load database configuration. No such file - ["/usr/share/redmine/instances/default/config/database.yml"]

现在我们有两个选择：

创建一个

对于 3.2 版本，您可以在此处找到示例：http://www.redmine.org/projects/redmine/repository/entry/branches/3.2-stable/config/database.yml.example经过一些小的修改后，我们可以得到如下内容：

cat /usr/share/redmine/instances/default/config/database.yml
# Setup is given for MySQL with ruby1.9.    
# Examples for PostgreSQL, SQLite3 and SQL Server can be found at the end.    
# Line indentation must be 2 spaces (no tabs).

production:    
  adapter: mysql2
  database: redmine_default
  host: localhost    
  username: root    
  password: "MySQLRootPassword"    
  encoding: utf8    
development:    
  adapter: mysql2    
  database: redmine_default
  host: localhost    
  username: root    
  password: ""
  encoding: utf8    
# Warning: The database defined as "test" will be erased and
# re-generated from your development database when you run "rake".    
# Do not set this db to the same as development or production.    
test:    
  adapter: mysql2    
  database: redmine_test    
  host: localhost    
  username: root    
  password: ""    
  encoding: utf8

生产数据库必须是 redmine_default或者至少是安装后留下的。我没有检查它是否适用于其他值。

复制安装过程中创建的

您可以将其移动到配置脚本尝试找到它的位置：

sudo cp /usr/share/redmine/config/database.yml /usr/share/redmine/instances/default/config/database.yml

现在我们已经拥有了您需要的一切，我们可以完成安装：

sudo apt-get -f install

Question 2

这实际上是 Redmine 3.2.3-1 中的一个已知错误：这个谷歌小组中有关于这个问题的讨论。

在配置过程中不要忘记创建“/etc/redmine/*/database.yml”。稍后创建它似乎也无法解决问题。

Question 3

大约 8 小时后，我终于完成了，我的 Redmine 再次运行。感谢 Manuel 和数十个其他 StackExchange 问题和答案。

如果接受的答案无法完全删除旧包，并收到错误，指出包处于非常糟糕的状态（dpkg: warning: package is in a very bad inconsistent state; you should reinstall it before attempting a removal）并且无法删除，sudo apt-get remove redmine --purge如 Manuel 所写，请执行以下操作。仍然更新 redmine.postrm 脚本，如 Manuel 在他的答案中所写。也许它对你有用，但对我没用。在 packages.ubuntu.com 手动下载 redmine 包，并sudo dpkg -i WHERE/THE/DOWNLOADED/PACKAGE/IS按照建议运行此评论。

对我有用的解决方案

如果这不起作用，那么尝试下一个对我有用的方法这里:sudo dpkg --remove --force-remove-reinstreq redmine我也sudo dpkg --purge --force-remove-reinstreq redmine删除了配置文件。之后sudo apt-get remove redmine也sudo apt-get autoremove && sudo apt-get autoclean

sudo apt-get install redmine redmine-mysql如果你在安装redmine时遇到以下错误

/usr/local/bin/bundle:23:in 'load': cannot load such file -- /usr/share/rubygems-integration/all/gems/bundler-1.11.2/exe/bundle (LoadError)
        from /usr/local/bin/bundle:23:in '<main>'

然后尝试查看是否有gem可用的命令（如果没有，不知道它来自哪里，但很可能是 ruby 包，所以只需安装它）并输入gem install bundler。如果你已经有了它，那就好了。它将被安装到INSTALLATION DIRECTORY你运行时可以看到的gem environment，在我的情况下/var/lib/gems/2.3.0。我不知道为什么，但我仍然没有bundler-1.11.2在上面提到的目录中，但无论如何，它继续运行。

我收到的下一个错误：

dbconfig-common: flushing administrative password
Could not find gem 'mysql2 (~> 0.4.0)' in any of the gem sources listed in your Gemfile or available on this machine.
Run `bundle install` to install missing gems.

安装 msyql2 gem

在安装之前，gem install mysql2我必须先安装sudo apt-get install libmysqlclient-dev（如果这不起作用，请先redmine再次删除该包，如上所示，我必须这样做）。这应该会自动随redmine包一起安装，但是是的……

如果你收到如下错误

Fetching: mysql2-0.4.4.gem (100%)
Building native extensions.  This could take a while...
ERROR:  Error installing mysql2:
        ERROR: Failed to build gem native extension.̀

并在给定的错误日志文件中包含类似以下内容的内容，gcc: error: unrecognized command line option然后运行sudo apt-get install gcc make。使用重试gem install mysql2̀。

继续安装

之后继续 Manuel 的回答。如果你在创建 database.yml 文件时遇到错误（顺便说一句，我在安装过程中没有创建该文件，因此无法复制，只能复制 Manuel 的示例，所以不用担心），然后继续安装，并得到类似这样的结果

[!] There was an error parsing 'Gemfile': undefined method 'values' for "Setup is given for MySQL with ruby1.9.":String. Bundler cannot continue.
 #  from /usr/share/redmine/Gemfile:67
 #  -------------------------------------------
 #    database_config = YAML::load(ERB.new(IO.read(database_file)).result)
 >    adapters = database_config.values.map {|c| c['adapter']}.compact.uniq
 #    if adapters.any?
 #  -------------------------------------------

那么不用担心，你只是太笨了，没有像我一样正确复制 database.yml 文件 :D 就我而言，我忘记了开头的注释符号#。如果你有其他问题，请使用以下命令检查你的 database.yml 文件http://www.yamllint.com/错误。也许如果你的密码包含一个，那么@你必须转义该字符（不知道如何），因为它是一个保留的 yaml 字符。

Question 4

尝试这个：

找到并注释掉此文件的删除行：

/var/lib/dpkg/info/redmine.postinst

看起来像这样：

\#rm -f /var/lib/redmine/Gemfile.lock

创建符号链接/var/lib/redmine/Gemfile.lock至/usr/share/redmine

尝试升级;-)
