我正在尝试在Ubuntu 17.10上安装CouchDB。使用apt-get时出现以下错误消息：
sudo apt-get install couchdb
Reading package lists... Done

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created

The following information may help to resolve the situation:
The following packages have unmet dependencies:
couchdb : Depends: libicu55 (>= 55.1-1~) but it is not installable
Recommends: python-progressbar but it is not going to be installed
E: Unable to correct problems, you have held broken packages.
通过快照安装并尝试启动数据库后，我仍然收到错误消息：
sudo -i -u couchdb couchdb/bin/couchdb
sudo: unable to change directory to /var/lib/couchdb: No such file or directory
sudo: unable to execute /bin/bash: No such file or directory
