Salome-Meca V2018 on Ubuntu 18.04

There are questions similar to mine on the forum, but none of the answers seem to solve my problems.

As background, I have had SM 2018, and probably two or three previous versions,  installed on Ubuntu 16.04. I upgraded Ubuntu 18.04 and everything worked fine.

After a disk crash I did a fresh install of Ubuntu 18.04 and SM 2018.

To Install SM, I had to install Python 2.7 and had to unzip the archive with 7zip as gzip corrupted the run file. (This may be of value to somebody)

I now have SM 2018 and SM 2017.0.2 installed and I have the same problems on both:
-Starting AsterStudy from SM gives me the message "Failed to activate module AsterStudy"
-The help files do not open from the Help menu. (The path to my browser is correctly specified  in  Preferences)
-Preferences are not saved, it opens with the defaults every time.
-Every time SM is opened the "Most recently used" file list is empty.

I can live with the last three, but I include them in case the problems are related.

My last possible clue, if I start SM from the terminal I get:
Error when trying to access active network connections.
Traceback (most recent call last):
  File "/home/johan/SM_2018/appli_V2018.0.1_public/bin/salome/PortManager.py", line 111, in __isNetworkConnectionActiveOnPort

Your help is appreciated. Thank you in advance

Hello,

as far as the first problem arises i think i have seen a workaround in the forum. Did you install Salome as root? I have had the same problem due to a root install i have once made. It did correct itself once i installed it as regular user.
I don't know if it can be of help but have a look at this thread: https:/_/code-aster.org/forum2/viewtopic.php?pid=57106#p57106

Thanks for the prompt response.

It is not installed as root and moving the files as in the link did not help. Unfortunately I do not know how to reinstall the libxx files in Ubuntu.

You could try with a new user account to check if it is related to your user environment.

Preferences, most recently used files...: $HOME/.config/salome directory may be corrupted. You can remove it (you only loose some prefs).

I was the next one with this problem.
On my machine helps this, and I don't know why:

LD_PRELOAD='/usr/$LIB/libstdc++.so.6' ./salome
(see thread code-aster.org/forum2/viewtopic.php?id=24078)
