Error Msg :

W: GPG error: http://[UBUNTU SERVER ADDRESS] precise Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY XXXXXXXXXXXXXXXX

에러를 만난 어떤 사람의 방법.....1

Run the following command - 
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 6AF0E1940624A220This did not solve my problem. I got connection timed out.
Generally Ubuntu key-server uses port 11371 which may be blocked by tour firewall. So you can use 80 as the port - 
sudo gpg --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys 6AF0E1940624A220 - See more at: http://opensourceforgeeks.blogspot.in/2013/04/w-gpg-error-httpppalaunchpadnet-precise.html#sthash.aQJUZnbW.dpuf

방법 2

   If the command are not doing it for you, you have to do it on your own. After a long research on this problem i finally decided that the best thing to do was manually download the key and add it.This is how i did it. Go to Ubuntu Key-server(keyserver.ubuntu.com). Here you can search your key. In my case it was 6AF0E1940624A220. Note while searching for key pre-append the key with 0x. So search for 0x6AF0E1940624A220 

Once you have copied the data to file. Save it. Then run the following command
sudo apt-key add key1 

You will get an "OK" response.

aniket@aniket-Compaq-610:~/Desktop$ sudo apt-key add key1
[sudo] password for aniket: 

And you are done. Repeat the procedure of other keys that might be missing.
Then you can run
sudo apt-get update
and you will not get any error. Update happens smoothly. Do let me know if you still have any doubts.

when I tried to install ubuntu 12.04, I got this error.

"/usr/lib/ubiquity/plugins/ubi-timezone.py" follows the message "ubiquity crashed with ValueError in raw_decode(): No JSON object could be decoded"

this is the discussion of ubuntu forum : "http://ubuntuforums.org/archive/index.php/t-1965802.html"

and I fixed this that unplugged network cable.

크롬의 문제, 혹은 우분투의 문제인 줄 알았으나... 결국 synergy의 업데이트로 수정됨.

sudo gnome-desktop-item-edit /usr/share/applications/ --create-new

If gnome-desktop-item-edit is not available (e.g., on Ubuntu), you can install it as follows.

$ sudo apt-get install --no-install-recommends gnome-panel

after creation .desktop file, If you can't see the icon on your dock, excute it once on terminal, and lock to launcher.

1. alz 


: ubuntu용 실행파일


: 소스파일

alz 포맷을 알집 없이 압축, 해제 할 수 있는 툴.

윈도우에 알집이 깔려있다면 상관없으나 개인적으로 알약과 알집은 찝찝해서 못깔겠;;; 

alz....대체 뭐가 좋은지도 모르겠고 왜 만들었는지도 모르겠고.... 그냥 그런 포맷이라면 그냥 통일하면 좋을텐데;; 

아무튼 소스 받아서 간단히 빌드해서 쓸 수 있음.

Ubuntu 쓰시는 분들은 linux-utf8 옵션으로 빌드하면 됨.

posix-utf8로 하면 iconv 깔아야 됨


2. egg

우분투에서 egg 형식의 압축파일을 풀 때 사용 가능. x86, x64 다 된다고 함.

폰트들을 보기 편하게 살짝 변경해 주는 기능.

sudo add-apt-repository ppa:no1wantdthisname/ppa

sudo apt-get update

sudo apt-get upgrade

sudo apt-get install fontconfig-infinality

직접 받아서 빌드하여 설치하는 방법은 요기에....


1. Clone the git repo

git clone https://github.com/chenxiaolong/Debian-Packages.git

cd Debian-Packages/

2. Install the build dependencies. Run the following

command and install the packages it lists using apt-get/synaptic/etc.

cd freetype-infinality/


cd ../fontconfig-infinality/


3. Build the packages:

cd ../freetype-infinality/


cd ../fontconfig-infinality/


4. Install the deb files:

cd ..

sudo dpkg -i freetype-infinality/*.deb fontconfig-infinality/*.deb

You'll need to reboot after installing the deb files. Enjoy the better

looking fonts!
