I have tried install package in Octave using this commmand

pkg install signal-1.4.0.taz.gz

but but I received an error:

error: pkg: failed to read package 'signal-1.4.0.taz.gz': Couldn't resolve host name
error: called from
  pkg at line 429 column 17

Does somebody know what does that mean?

You have mis-spelled the name of the package's tarball. It is likely signal-1.4.0.tar.gz rather than signal-1.4.0.taz.gz

pkg install signal-1.4.0.tar.gz
