Hello all, I am trying to install koha (and use Linux) for the first time and am not very Linux savvy at all I am afraid. I am having issues with installing idzebra but keep getting error messages regarding missing dependency libyaz3 which won't install because I keep getting this error message >> Depends: libgnutls13 (>=1.4.0-0) but it is not installable

...

Depends: libicu36 but it is not installable Can anyone tell me what I am doing wrong and how to fix it? Thanks Leila
