Overview¶

When working with Git, there can various of problems you can meet. And with by the timeing, the troubleshooting of Git need to reduced less.

Problems¶

[RESOLVED] Broken branch remote on the local tree¶

Description: When pull branch on the local machine, you will see this error below

git pull origin master
# fatal: bad object refs/remotes/origin/<branch-name>
# error: https://github.com/<organization>/<project>.git did not send all necessary objects

Troubleshooting: The objects on the path refs/remotes/origin/<branch-name> not exist

Resolved by:

1. Remove the head of the target branch that not send any necessary objects of git

rm -rf .git/refs/remotes/origin/

1. Fetch with prune for the project

This will fetch all current branch that not exist in the local repository.

You will see something like this below

$ git fetch --prune
# From https://github.com/<orgranization>/<project>
#    xxxxxxx..xxxxxxx  master            -> origin/master
#  * [new branch]      <branch-deployment-example> -> origin/<branch-deployment-example>
#  * [new branch]      <feature-example>   -> origin/<feature-example>
#    xxxxxxx..xxxxxxx  production        -> origin/production

1. Normal run as example

$ git pull origin master
From https://github.com/<orgranization>/<project>
 * branch            master     -> FETCH_HEAD
Already up to date.

Reference:

• [1]: BitBucket Git Error: did not send all necessary objects

[RESOLVED] Could not resolve host: github.com¶

Describle: When you pull some branch (example: master). The error has been captured Could not resolve host

git pull origin master
# fatal: unable to access 'https://github.com/[ORGANIZATION]/[PROJECT].git/': Could not resolve host: github.com

Come from:

• You has available tunnel proxy to the host that make the target can't not resolve

Solved by:

• Turn off some VPN construction (like) OpenVPN

• Turn off 3^rd-party like Proxy

You can use the git+ssh URI scheme, but you must set a username. Notice the git@ part in the URI:

pip install git+ssh://git@github.com/echweb/echweb-utils.git

Also read about deploy keys.

PS: In my installation, the "git+ssh" URI scheme works only with "editable" requirements:

pip install -e URI#egg=EggName

Remember: Change the : character that git remote -v prints to a / character before using the remote's address in the pip command:

$ git remote -v
# origin git@github.com:echweb/echweb-utils.git (fetch)

^ change this to a '/' character¶

If you forget, you will get this error:

ssh: Could not resolve hostname github.com:echweb: nodename nor servname provided, or not known
