Yesterday i found out an error when i tried to start my vagrant. It’s related to ruby script resolv.rb. Here’s the full error detail :

Not so sure what causing this, probably because i just update my ArchMerge (now rebranded as ArcoLinux) the day before. After couple minutes of googling, i found some people report this problem on github.

One of the commenter, @chrisroberts, suggest a solution and it’s worked for me.

$ export VAGRANT_DISABLE_RESOLV_REPLACE=1

So basically by setting that environtment variable, solve my problem. To make it autorun every session, I just need to add those line in my ~/.bashrc file.
