PGP: Not enough random bytes available. Please do some other work to give the OS a chance to collect more entropy
提问by user1524529
Setup : Ubuntu Server on Virtual Machine with 6 cores and 3GB of RAM.
设置：虚拟机上的 Ubuntu 服务器，具有 6 个内核和 3GB 内存。
when I am trying to generate a asymmetric key pairvia GPGlike this gpg --gen-key. I get the following error :
当我试图生成asymmetric key pair通过GPG这样的gpg --gen-key。我收到以下错误：
Not enough random bytes available. Please do some other work to give
the OS a chance to collect more entropy!
I tried to google a little bit. This is what I realise ,
I need to fire up another terminal and type in cat /udev/random--> It randomly generates a series of randomly generated values to increase the entropy.
我试着用谷歌搜索一下。这就是我意识到的，我需要启动另一个终端并输入cat /udev/random--> 它随机生成一系列随机生成的值以增加熵。
I dont see any change in here watch cat /proc/sys/kernel/random/entropy_avail
我没有看到这里有任何变化 watch cat /proc/sys/kernel/random/entropy_avail
and it still persists to give me the same error
它仍然给我同样的错误

This is what is the solution I found to it
这是我找到的解决方案
I had to do gpg --gen-key --no-use-agent
我必须做 gpg --gen-key --no-use-agent
after that in an another terminal I fired up cat /dev/random
之后在另一个终端我启动了 cat /dev/random
This fortunately for me worked at the end :)
幸运的是，这对我来说最终起作用了:)

Running $ sudo rngd -r /dev/urandom
跑步 $ sudo rngd -r /dev/urandom
Then running $ gpg --user-agent
然后运行 $ gpg --user-agent
and $ ps -ef | egrep rngd(shows process number of rngd, e.g. 9999)
和$ ps -ef | egrep rngd（显示 rngd 的进程号，例如 9999）
then $ sudo kill 9999
然后 $ sudo kill 9999
worked for me on my Ubuntu 13.04 system.
在我的 Ubuntu 13.04 系统上为我工作。

Run the following:
运行以下命令：
find / > /dev/null
That helped me quickly to complete my key generation.
这帮助我快速完成了我的密钥生成。

Try installing haveged, this is a daemon, which helps the system with generating random numbers for your key.
尝试安装haveged，这是一个守护进程，可帮助系统为您的密钥生成随机数。
sudo aptitude install haveged
sudo aptitude install haveged

Step 1 Run on a shell first and let it run ls / -R
步骤 1 首先在 shell 上运行并让它运行 ls / -R
Step 2 Now try to generate the key it will be done
第 2 步现在尝试生成将要完成的密钥

Just use another random maker under Ubuntu:
只需在 Ubuntu 下使用另一个随机制造商：
mv /dev/random /dev/chaos && ln -s /dev/urandom /dev/random
and retry your gpg command
并重试您的 gpg 命令

Trying installing rngd. If your CPU if reasonably modern it will have a hardware random number generator built in, and rngd will use this to generate enough entropy.
尝试安装 rngd。如果您的 CPU 相当现代，它将内置一个硬件随机数生成器，并且 rngd 将使用它来生成足够的熵。
Watch outfor people telling you to run rngd -r /dev/urandom. While this will get rid of your error, it does it by faking entropy and leads to insecure keys.
当心人们告诉你跑步rngd -r /dev/urandom。虽然这将消除您的错误，但它是通过伪造熵并导致不安全的密钥来实现的。

I did apt-get install libreoffice and apt-get remove libreoffice* a couple times. That did the trick. Pick some other big fat program for yourself to use.
我做了几次 apt-get install libreoffice 和 apt-get remove libreoffice* 。这就是诀窍。选择一些其他的大胖程序供自己使用。

try running (in another terminal tab)
$cat /proc/sys/kernel/random/entropy_availon command line, it it returns less than 100-200, then something is wrong, install rng-tools
$sudo apt-get install rng-tools
尝试$cat /proc/sys/kernel/random/entropy_avail在命令行上运行（在另一个终端选项卡中）
，它返回小于 100-200，然后出现问题，安装 rng-tools
$sudo apt-get install rng-tools
That should have fixed this issue, check the previous tab and you have the key
这应该已经解决了这个问题，检查上一个选项卡，你有钥匙

I've tried different tricks while watching the /proc/sys/kernel/random/entropy_availvalue. But trying to make an MD5 hash of an entire disk really gave my system entropy on steroidswithout installing extra packages.
我在观察/proc/sys/kernel/random/entropy_avail价值时尝试了不同的技巧。但是尝试制作整个磁盘的 MD5 哈希确实给了我的系统熵，而无需安装额外的软件包。
find /dev/disk/by-uuid/ -type l | xargs md5sum
find /dev/disk/by-uuid/ -type l | xargs md5sum
