I have upgraded julia-client package in Atom. There was a prompt to upgrade Atom package in Juno (using Pkg.update). And afterwards Atom Repl gives segmentation fault when doing `using Plots` and pressing any button. The similar errors appear after writing `using` with some other modules (e.g. user-defined module that needed pre-compilation).

On the other hand plotting in terminal works fine.

I wouldn’t like to delete my .julia file (I had to do it a month ago). Does anybody know how to proceed?

My Julia is 1.0.5

The error is as follows:

```julia

I have also noticed (while running `using`) in terminal following message:

I can repro the issue on Julia 1.0.x, but not on Julia 1.3. Can you upgrade the version of Julia you use?

Well, in general yes.  
But  
I had 1.0.3 and I had many problems with `Plots`, so I upgraded to 1.0.5 (which is LTS) so as I will not have to upgrade for a long time. And after my upgrade to 1.0.5 I still had to remove folder .julia and reinstall everything. So I would like to try other solution if it exists.

Fair enough. Do you remember which version of Atom.jl you had before you had those segfaults?

I don’t know whether I can find it anywhere. I checked I upgraded Julia to 1.0.5 on Feb 3. Looking at the releases dates of Atom.jl it should be 0.11.3 by then.

Yeah, I can see the segfaults on Julia 1.0.x, but not with newer Julia versions. I’d recommend upgrading until we can figure out what’s going wrong.

Hi @pfitzseb@pjgorski and maybe @mike_k 🙂

Ok so specifically re: Issue: **signal (11): Segmentation fault** in expression starting at **no file:0 at** /buildworker/worker/package\_linux64/build/src/ **codegen.cpp** :1191  
when using julia\> **versioninfo()**  **\>\>** When using Atom IDE w Juno w **Julia Version 1.0.5 \*\* w OS: Linux (x86\_64-pc-linux-gnu)**

It was my goof because I moved my Julia code and Atom IDE to my new AMD Threadripper Machine and I needed to install various additional Ubuntu libraries ;

IOW **Summarizing below**

**signal (11): Segmentation fault -** _yada yada_ **-**  **codegen.cpp**  **means that one’s** `cmake` `is` `missing `

`ergo Solution ` `was` `:`

`sudo apt-get install cmake `

`-` `or-`

`use Synaptic to search for and install` ` cmake` ` `

`More generally (Julia developers) you may want to read over this`

**`-AND This-`**

From (OLD) file: _JuliaProQuickStartGuideLinux.pdf_

_ **Required Julia libraries** _

**Section : 2.1.3 Prerequisites for Installation on Ubuntu 16.04**

When installing JuliaPro on Ubuntu 16.04, a particular set of system libraries

`need to be installed by a user with appropriate Administrator or sudo privileges.`

On Debian-based distributions (e.g. Ubuntu ), you can easily install them with `apt-get` :

```julia
sudo apt-get install build-essential libatomic1 python gfortran perl wget m4 cmake pkg-config

Unfortunately this didn’t work for me (same versioninfo output). And it would be strange if it worked in my case, because I obtain those errors only in Juno, not in Julia in terminal.

In the new installation of Julia in the new device (apart from the case described here) I sometimes also get Seg fault, when doing some operations, e.g. ctrl+c, ctrl+v, ctrl+z with mixing the place I am currently in (editor or repl)

Personally, I find this strange that after almost a year the most recommended Julia IDE in Julia LTS version is still producing such an error. Is nobody using Juno in Julia LTS? Or are everybody so accustomed to such errors in Julia?

most have switched to microsoft visual studio code and [https://www.julia-vscode.org/](https://www.julia-vscode.org/)  
it is the recommended IDE for Julia by now
