I'm trying to edit this snippet on the LSR but I do not have the rights to
do so.
A fret number should be used for the e on second string (in bold below):

music =  \relative c' {
  \voiceOne
  \repeat volta 2 {
    g a b c\glissando
  }
  \alternative {
    { d1 }
    { \repeatGliss c *e1\2* }
  }
}
