If git fetch gets interrupted for example by Ctrl-C or caused by connectivity problems, after that git fetch and also git pull fail to work.

I believe this is not related to the repository. Using git clone to create a copy of this broken local repository into a new local repository does not fix this. The only solution I know so far is to git clone the entire remote repository (origin/master) into a new local repository. But is there any better (faster) solution?
There is Debian bug report that has last message from February 2011. Is this the same bug I have or is there already a fix or any solution or workaround to this? My git version is 1.7.10.

Git fetch summary In review, git fetch is a primary command used to download contents from a remote repository. git fetch is used in conjunction with git remote , git branch , git checkout , and git reset to update a local repository to the state of a remote.
Fetch changes Fetched changes are stored as a remote branch, which gives you a chance to review them before you merge them with your files. Since fetch does not affect your local development environment, this is a safe way to get an update of all changes to a remote repository.
When you do a git fetch, it fetches all the changes from the remote repository and stores it in a separate branch in your local repository. You can reflect those changes in your corresponding branches by merging. So basically, git pull = git fetch + git merge.
Try these commands:
git fsck
git gc
find a *.pack.temp in .git/objects/pack in your local repository. Then find an .idx file with same basename, and move both of them away (or remove them, but it is better to be safe than sorry). Rerun git fetch and it should work (well, it did for me).
For example:
% git fetch
