Installing Git on Linux Mint Debian

Question

Background
I recently moved to Linux Mint. I installed the LMDE201403 and pretty much have my environment setup. However, I need to install Git for my version control.

I have searched the internet for a number of ways to do this. I'll list the two that were recommended for LMDE201403:

1. Use apt-get to install git-core sudo apt-get install git-core --fix-missing
2. install git from the source (1.9.0)

Both of these fail for me. If I try to install it from the source I get a compile error because I'm missing the <curl/curl.h> headers. I have tried to install these using apt, but it fails to do so because the dependencies fail to authenticate.

If I try to install git-core through apt I also get some authentication errors.

I believe that the reason that I can't install this is because I'm missing some respositories. I don't know if this is the case and I haven't been able to find any backport or related repositories that I would need to install this.

Question(s):
How do you install git-core on LMDE201403?

Any information that helps in the process would be greatly appreciated, and if any details about error messages or my environment are needed I am ready to provide them.

Thanks for your help.

Answer 1

LMDE is debian based, so googling of "debian WARNING: The following packages cannot be authenticated!" immediately finds excellent https://wiki.debian.org/SecureApt#How_to_find_and_add_a_key page.

Try so:

wget https://ftp-master.debian.org/keys/archive-key-7.0.asc
gpg --import archive-key-7.0.asc

Then "apt-get update" and "apt-get install --no-install-recommends git".

And if it doesn't help, try workaround:

apt-get install --allow-unauthenticated ...

Answer 2

The "WARNING: The following packages cannot be authenticated!" means that the package-providing repository can't be authenticated, you should first try to refresh APT's repository cache(sudo apt-get udpate) to see if the issue is solved automatically, if not you should try to install/renew the GPG key of the Ubuntu repository(assuming that those packages are provided from Ubuntu) which is provided by ubuntu-keyring package.
$ sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 437D05b5 then execute sudo apt-get udpate again, verify if there's any warning messages.
