I am trying to install Liquidity on a VM with Ubuntu 18.04.2 LTS following this instruction http://www.liquidity-lang.org/doc/installation/index.html . Everything goes well until stage 4: Install Liquidity dependencies: make build-deps. After entering this command, I get the error message:

opam install . --deps-only

In realtà,error 57: Synopsis and description must not be both empty dovrebbeessere visto come un avvertimentoemesso da opam.Ilmotivo delfallimento vienefornito allafine.È dovuto all'assenza di alcune dipendenze di sistema.Prova ainstallarli come segueprima di ricompilare Liquidity:

 sudo apt-get install libcurl4-gnutls-dev libsodium-dev

Actually, error 57: Synopsis and description must not be both empty should be seen as a warning emitted by opam. The reason of the failure is given at the end. It's due to absence of some system dependencies. Try to install them as follows before recompiling Liquidity:

sudo apt-get install libcurl4-gnutls-dev libsodium-dev

Provo `sudo apt-getinstall libcurl4-gnutls-dev libsodium-dev`e ottengo questo:` s-dev libsodium-dev Lettura deglielenchi deipacchetti ... Fatto Costruzione dell'albero delle dipendenze Lettura delleinformazioni sullo stato ... Fatto E: Impossibileindividuareilpacchetto libcurl4-gnutls-dev E: Impossibileindividuareilpacchetto libsodium-dev "

I try `sudo apt-get install libcurl4-gnutls-dev libsodium-dev` and get this: `s-dev libsodium-dev Reading package lists... Done Building dependency tree Reading state information... Done E: Unable to locate package libcurl4-gnutls-dev E: Unable to locate package libsodium-dev `

prova `sudo apt-get update`per aggiornare la cache deipacchettiprima di riprovare` sudo apt-getinstall ... `

try `sudo apt-get update` to update packages cache before re-trying `sudo apt-get install ...`

Utilizzo anche Ubuntu 18.04e `apt-cache search libsodium-dev` restituisce:` libsodium-dev - Comunicazione di rete,crittografiae libreria difirma - header`.Potresti ancheprovare questo comando sullatua VMper vedere setrovailpacchetto.Seilpacchettonon vienetrovato,forse `/etc/apt/sources.list `non contienetutte lefonti" standard "

I'm running Ubuntu 18.04 as well, and `apt-cache search libsodium-dev` returns: `libsodium-dev - Network communication, cryptography and signaturing library - headers`. You may want to also try this command on your VM to see if it finds the package. If the package is not found then, maybe `/etc/apt/sources.list ` does not contain all "standard" sources
