<p>Dear Peter,</p>
<p><br>
</p>
<p>thanks for your suggestions!</p>
<p>Synaptic shows:<br>
</p>
<p><span style="font-variant-ligatures: no-common-ligatures"
class=""> libqscintilla2-qt5-15 </span>2.11.2+dfsg-6</p>
<p>My mint (20.3) is fresh, but not mint ;0)</p>
<p>Regarding python, usually I pip install as a normal user. I am
not quite sure what then gets precedence here... mcstas will call
the system installed package, right ? Or does it inherit from the
user calling mcgui? <br>
</p>
<p><br>
</p>
<p>I am now running mcstas 2.7.1 from ppa and actually cannot find
execute mcrun as such:</p>
<p> jfmoulin@jfm17:~$ mcrun --write-user-config<br>
<br>
Command 'mcrun' not found, did you mean:<br>
<br>
command 'crun' from deb crun (0.12.1+dfsg-1)<br>
command 'mcron' from deb mcron (1.0.8-1build1)<br>
<br>
Try: sudo apt install <deb name></p>
<p><br>
</p>
<p>mcrun.pl is actually found at usr/bin/mcrun.pl though. Link
missing?<br>
</p>
<p><br>
</p>
<p>Cheers,</p>
<p><br>
</p>
<p>Jean-François<br>

<div>Which exact Linux Mint are you on? As I remember Mint is a

<div>Is your Mint python “in mint condition” ( ;-) ) or has it
