总述

今天遇到两个问题，列一下

安装东西时

现象

sudo apt-get install ***

gzip: stdout: No space left on device            
E: mkinitramfs failure cpio 141 gzip 1

no space? 好吧，看一下空间

df -h

解决

当更新 ubunbu 时，升级的内核会都存在 /boot 下，时间长了，升级的次数多了，满了。。。，列出你已经安装的 kernel：

aptitude search ~ilinux-image 

uname -a // 可见你的当前的内核

sudo apt-get autoremove linux-image-3.8.0-19-generic

remove one by one,don't remove packages such as linux-image-generic and just the previous one of the kernel you are using

Meteor

现象

meteor

.meteor/tools/3cba50c44a/tools/run.js:425
    throw e;
          ^
Error: watch ENOSPC

解决

echo fs.inotify.max_user_watches=524288 | sudo tee -a /etc/sysctl.conf && sudo sysctl -p

You have run out of watches: The system has a limit to how many files can be watched by a user.This command increases the maximum amount of watches a user can have.
