Installation on Ubuntu Subsytem - Failed to fetch

Hello everyone,

Manytimes, I installed OpenFoam on my home computer and office pc. However, nowadays I can not re-install OpenFoam on my home pc. I tried everything and look at every forum. But I could not solve the problem. While I tried to install OF, I follow the instructures. But after, sudo apt-get update; I write the sudo apt-get -y install openfoam6 and I get this:

Code:

E: Failed to fetch https://netix.dl.sourceforge.net/pro...0620_amd64.deb  Could not handshake: The TLS connection was non-properly terminated. [IP: 87.121.121.2 443]

In upper lines I saw this:

Code:

After this operation, 1929 MB of additional disk space will be used.

Quick answer: After a quick search for:

Code:

ubuntu wsl Could not handshake: The TLS connection was non-properly terminated.

it seems that it's due to a proxy error for HTTPS handling. Brief instructions on how to fix that are provided here: https://askubuntu.com/a/1014978

OK the problem was occured becaouse of my antivir-software. It solved now. Thank you.!!:D:D

I am getting the same error. Do I need to restart the process of installation from beginning or do we have any other solution? Please help

Hi,

The error related to the initial post was due to the fact that an antivirus tool was blocking the installation.

If this is not the case for you, clean everything and restart the installation following step by step the respective guides. See here.

Best,
Petros

Thank you for reply. The error was due to bad network. But I restarted the process by entering:

sudo apt-get update

sudo apt-get -y install openfoam8

and it worked :)
