git checkout v.4.4.0 error

I get an error in git checkout.
Would you please tell me what to do?

Thank you,

[toml12953]

Try this:
git checkout 4.4.0-17763-Microsoft

That worked for me.

Thank @toml12953 for your response.

I tried below:

kei@xxxx:/usr/src/4.4.0-17763-Microsoft$ git checkout 4.4.0-17763-Microsoft
fatal: Unable to create '/usr/src/4.4.0-17763-Microsoft/.git/index.lock': Permission denied
kei@xxxx:/usr/src/4.4.0-17763-Microsoft$ sudo git checkout 4.4.0-17763-Microsoft
[sudo] password for kei:
error: pathspec '4.4.0-17763-Microsoft' did not match any file(s) known to git.
kei@xxxx:/usr/src/4.4.0-17763-Microsoft$

Thank you,

@keides2 , a little bit late, but your problem happened because your command missed a sudo.

kei@xxxx:/usr/src/4.4.0-17763-Microsoft$ sudo git checkout 4.4.0-17763-Microsoft

My commit above solves the problem with another approach: compile the kernel under you home dir and you won't need to sudo.
