How to solve "Error: (converted from warning) Setting LC_CTYPE failed, using "C"?

Question

I am trying to install a library in R and I have a this message
Error: (converted from warning) Setting LC_CTYPE failed, using "C"

What I saw is some solutions but for mac User, like this one
Type in your terminal
system("defaults write org.R-project.R force.LANG en_US.UTF-8")

But I am working in a server with FEDORA an this is not working for me, any help will be awesome.
Thank you!

I had the same problem with a server. Our support said I should try the command:
echo $LC_CTYPE

The system returned UTF-8 where it should return nothing.
The solution for me was to use the following command:
unset LC_CTYPE
