Minecraft forge crash on Linux mint

[spyridon233]

When i use minecraft with forge on linux mint, the game crashes. And this is what the report says:    Couldn't get hash for net/minecraftforge/forge/1.12.2-14.23.5.2814/forge-1.12.2-14.23.5.2814.jar from http://files.minecraftforge.net/maven/net/minecraftforge/forge/1.12.2-14.23.5.2814/forge-1.12.2-14.23.5.2814.jar.sha1: HTTP 404: Not Found

Couldn't get hash for com/typesafe/akka/akka-actor_2.11/2.3.3/akka-actor_2.11-2.3.3.jar from http://files.minecraftforge.net/maven/com/typesafe/akka/akka-actor_2.11/2.3.3/akka-actor_2.11-2.3.3.jar.sha1: HTTP 404: Not Found

Have local file /home/costas/.minecraft/libraries/net/minecraftforge/forge/1.12.2-14.23.5.2814/forge-1.12.2-14.23.5.2814.jar but don't know what size or hash it should be. Have to assume it's good.

Couldn't get hash for org/scala-lang/scala-actors-migration_2.11/1.1.0/scala-actors-migration_2.11-1.1.0.jar from http://files.minecraftforge.net/maven/org/scala-lang/scala-actors-migration_2.11/1.1.0/scala-actors-migration_2.11-1.1.0.jar.sha1: HTTP 404: Not Found

etc..

 

Then it says:  Version does not support log configuration, will assume one plaintext entry per line

Process crashed with exit code 1

 

When i go to the version folder i see the .jon but not the .jar

 

any idea of what's going on ?
