Doesn't work with Linux Mint 19 Tara

[tometchy]

On Linux Mint 19 Tara, after installing and typing "git fetch" I get runtime exception that this OS doesn't have secure credential storage. I can't see in docs how can I install such a dependency, or what should I do in this case. Exception is:

Fatal: java.lang.RuntimeException encountered.  Details:
Secure credential storage is not available on this operating system. You may opt-in to store credentials in an unencrypted file under your user home directory by running 'git config --global credential.canFallBackToInsecureStore true'.
fatal: credential helper '!/usr/lib/jvm/java-11-openjdk-amd64/bin/java -Ddebug=false -Djava.net.useSystemProxies=true -jar /home/tometchy/git-credential-manager/git-credential-manager-2.0.4.jar' told us to quit

My OS version is:
$ cat /etc/*-release

My git version is 2.17.1.

I know I can fall back to plain text password storing, but this is not why I wanted to install secure manager :)

As there is still no answer I was forced to use different solution - libsecret. For those who ended up with similar situation I have described on my blog how to install and configure it, it's pretty simple - softwaredeveloper.blog/git-credential-storage-libsecret

I'm closing because it's being discussed in another issue - #115.
