to 2017.<br>

</span>No, usually (as a command line geek) I'm pretty much aware of PATH and<br>
other environment variables. :-)<br>

</span>Let me tell what I did. :-)<br>
<br>
On a second non-private laptop I installed texlive 2017 and adjusted<br>
the PATH, and all was fine.<br>
<br>
Then I thought: texlive 2016 is very old as I hadn't done any update<br>
for an awful lot of time. So, I should at least get the newest stuff of<br>
texlive 2016.<br>
<br>
I adjusted the PATH back to 2016 and did: tlmgr update --all<br>
<br>
Of course I got told to do a --self which i did. Then I restarted the<br>
'tlmgr update --all', went to the kitchenn for a coffee and when<br>
being back I got a list of 880 packages to update.<br>
<br>
On the one hand I was wondering about the sheer amount of packages<br>
to update on the other hand I new that I hadn't done an update "for<br>
ages" and I also know on a daily basis how busy authors do update their<br>
packages. So I did the mass update, and was happy.<br>
<br>
Some time later, Harald König told me that it happened to him, after an<br>
upgrade in texlive 2016 ,that now his /usr/local/texlive/2016 contains<br>
texlive 2017.<br>
<br>
Being back at home I checked my updated 2016 tree, and discovered the<br>
same. Actually, in my case it wasn't important if I have still the 2016<br>
lying around. So, instead to recover from backup I deleted the 2016<br>
(containing 2017) tree.<br>
