Really old versions are no longer supported.

Please update to a modern (1.14.4/1.15.2) version to receive support.

 

More information on supported versions can be found in the LTS link at the top of every page.

Thanks for respond.

So i cant play older modpacks on ubuntu /linux ? or forge arent support new ubuntu ? or what
