ruby-on-rails - 橡胶 : Unmet Dependencies for libapache2-mod-passenger

Question

当我尝试使用 rubber 进行部署时，我收到以下错误:

The following packages have unmet dependencies:
** [out :: staging.xxx.com] 
** [out :: staging.xxx.com] libapache2-mod-passenger : Depends:   passenger (= 1:5.0.8-1~trusty1) but it is not going to be installed
** [out :: staging.xxx.com] 
** [out :: staging.xxx.com] E
** [out :: staging.xxx.com] :
** [out :: staging.xxx.com] Unable to correct problems, you have held broken packages.

我该怎么做才能解决这个问题？

Answer 1

同样的事情发生在我身上。

我试过像@Phil 说的那样修改版本号，在我的 rubber-passenger.yml 中更改它们根据 https://oss-binaries.phusionpassenger.com/apt/passenger/dists/trusty/main/binary-amd64/Packages 任意递增文件然后运行 ​​cap <alias> rubber:install_packages .这太可怕了，大约在这里:

# passenger_version: '1:5.0.10-1~`lsb_release -sc`1' # fail
# passenger_version: '1:5.0.11-1~`lsb_release -sc`1' # fail
# passenger_version: '1:5.0.13-1~`lsb_release -sc`1' # fail
# passenger_version: '1:5.0.14-1~`lsb_release -sc`1' # fail
# passenger_version: '1:5.0.15-1~`lsb_release -sc`1' # fail
# passenger_version: '1:5.0.16-1~`lsb_release -sc`1'
# passenger_version: '1:5.0.18-1~`lsb_release -sc`1'
# passenger_version: '1:5.0.19-1~`lsb_release -sc`1'
# passenger_version: '1:5.0.20-1~`lsb_release -sc`1'
# passenger_version: '1:5.0.21-1~`lsb_release -sc`1'
# passenger_version: '1:5.0.22-1~`lsb_release -sc`1'
# passenger_version: '1:5.0.23-1~`lsb_release -sc`1'
# passenger_version: '1:5.0.24-1~`lsb_release -sc`1'
# passenger_version: '1:5.0.25-1~`lsb_release -sc`1'
# passenger_version: '1:5.0.26-1~`lsb_release -sc`1'
# passenger_version: '1:5.0.27-1~`lsb_release -sc`1'

我受够了，只是删除了版本号。那奏效了。所以现在我的 roles规范 rubber-passenger.yml看起来像这样:

roles:
  passenger:
    # packages: [apache2-mpm-prefork, apache2-prefork-dev, libcurl4-openssl-dev, libapache2-mod-xsendfile, [libapache2-mod-passenger, "#{passenger_version}"]]
    packages: [apache2-mpm-prefork, apache2-prefork-dev, libcurl4-openssl-dev, libapache2-mod-xsendfile, libapache2-mod-passenger]
    rolling_restart_port: "#{passenger_listen_port}"

  web_tools:
    rolling_restart_port: "#{web_tools_port}"
