Install NCS 2.7.0 failed

[ekidsalan123]

I'm installing NCS with Toolchain Manager v1.5.2, but failed at installing SDK

What should I do to check the installation?

There are multiple errors:
Failed to clone the repositories: Error: error: RPC failed; curl 92 HTTP/2 stream 0 was not closed cleanly: CANCEL (err 8) error: 359 bytes of body are still expected fetch-pack: unexpected disconnect while reading sideband packet fatal: early EOF fatal: fetch-pack: invalid index-pack output FATAL ERROR: command exited with status 128: fetch -f --tags -- https://github.com/nrfconnect/sdk-zephyr v3.6.99-ncs2 Error: Launched process exited with non-zero status: 128 Error: Subprocess C:\Users\user\AppData\Roaming\nrfconnect\nrfutil-sandboxes\toolchain-manager\0.15.0\bin\nrfutil-toolchain-manager.exe failed with unexpected exit code Some(128)

Hi 

I see some reports fixing similar issues by increasing the buffer size for git: 

git config --global http.postBuffer 524288000

Which version of NCS are you trying to install? The preferred way is to use the VScode extension to install the SDK. 
If you are still facing issues you could also to save some time with the troubleshooting download the sdk from here https://files.nordicsemi.com/ui/native/ncs-src-mirror/external/
