Mbsync and imap login problem

Written by Solène, on 17 May 2016.
Tags: #solved #email

I have not found any answer about this so I share my fixed. I wanted to use mbsync with one IMAP server and encountered the following error.

IMAP command 'AUTHENTICATE DIGEST-MD5' returned an error: NO Authentication failed

A fix is to add the following to your ~/.mbsyncrc IMAPAccount declaration.

AuthMechs LOGIN

Using LOGIN instead of DIGEST-MD5 is still secure if you have an encrypted connection (IMAPS or STARTTLS). The login will be given plaintext inside the connection.

Git push to non-bare repository

You have a git repository where you work in, and you would like to work on a clone of it and push the data back to it ? You may encounter issues if your git repository isn’t a bare one. I have been facing this problem by using gitit, which works with a non-bare git repository.

What is a bare git repository ?

Here is how to create a bare repository and what it looks like.

$ git init --bare repo 
$ ls -a repo/
.            HEAD         config       hooks        objects
..           branches     description  info         refs

You can’t work in this, but this is the kind of repository that should be used to store/push/clone etc..

What is a non-bare git repository ?

Here is how to create a non-bare repository and what it looks like.

$ git init repo2
$ ls -a repo2
.    ..   .git

You may use this one for local use, but you may want to clone it later, and work with this repository and doing push/pull. That’s how gitit works, it has a folder “wikidata” that should be initiated as git, and it will works locally. But if you want to clone it on your computer, work on the documentation and then push your changes to gitit, you may get this error when pushing :

Problem when pushing

I cloned the repository, made changes, committed and now I want to push, but no…

git is unhappy, I can’t push


You can fix this “problem” by changing a config in the server repository with this command :

$ git config --local receive.denyCurrentBranch updateInstead

Now you should be able to push to your non-bare repository.
