Comment # 8 on bug 1054509 from Erico Rolinski

This bug maybe is duplicate from this:
https://bugzilla.opensuse.org/show_bug.cgi?id=1054448

In my tests the TERM "xterm-color" works too.

For YaST only I set alias in ~/.alias or "~/.bashrc" (or your shell) file:
alias sudo='sudo '
alias yast='TERM=xterm-color yast'

OR

For a user environment config set alias for sudo in ~/.alias or "~/.bashrc" (or
your shell) file:
alias sudo='sudo '

And set TERM in "~./bashrc (or your shell) file"
export TERM=xterm-color

Note: for root the file ".bashrc" doesn't exist by default
