b. update fastboot

sudo apt install android-tools-adb android-tools-fastboot

c. add usb vendor to the driver(나의 경우엔 이걸로 해결)

$lsusb

Bus 003 Device 010: ID 18d1:d00d Google Inc.

Bus 003 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

$sudo vi /etc/udev/rules.d/51-android.rules

SUBSYSTEM=="usb", ATTRS{idVendor}=="18d1", ATTRS{idProduct}=="d00d", MODE="0666", GROUP="plugdev"

$sudo service udev restart

./source build/envsetup.sh

Error message: 

ninja: error: 'out/host/common/obj/JAVA_LIBRARIES/javapoet-prebuilt-jar_intermediates/classes.jar', needed by 'out/target/common/obj/APPS/Dialer_intermediates/classes-full-debug.jar', missing and no known rule to make it

https://android-review.googlesource.com/c/platform/external/f2fs-tools/+/683306 

With those 3 patches (first one was 

https://android-review.googlesource.com/c/platform/prebuilts/tools/+/682002 

for anyone who missed that), android-p-preview-2 builds and mostly 

works (tried on Nexus 6P with latest blobs from 

https://developers.google.com/android/blobs-preview ).

If the client and server are unable to agree on a mutual set of parameters then the connection will fail. OpenSSH (7.0 and greater) will produce an error message like this:

For the case of the above error message, OpenSSH can be configured to enable the diffie-hellman-group1-sha1 key exchange algorithm (or any other that is disabled by default) using the KexAlgorithms option - either on the command-line:

or in the ~/.ssh/config file:

OpenSSH 7.0 이상에서는 해당 옵션이 기본으로 enable 되어 있지 않기 때문에

옵션을 넣어줘야 한다.

항상 넣기 귀찮으니 config를 만들어서 넣고 쓰도록 하자.

config파일이 없으면 그냥 생성하면 적용 됨.
