Subject: bug#25221: Packages manager not working in WSL emacs-25 build
Date: Sat, 15 Apr 2017 00:32:28 +0200

Just for the record..

After the upgrade to Win10 Creators Update (clean Reset from 
Anniversary). I reinstalled WSL that now is Ubuntu 16.04 and so Emacs. 
The package installed is 24.5.1.

While with previous installation (WSL-Ubuntu 14.04, Emacs-24.3), Emacs 
worked fine, also with the package manager, now it shows the same issues 
I had with Emacs-25 branch or Emacs-master.. It seems I can't 
install/upgrade Elpa/Melpa packages any more...

The only good news is that it seems that Emacs can be built without the 
"echo 0 | sudo tee /proc/sys/kernel/randomize_va_space" workaround..


Any suggestion about how to upgrade Elpa/Melpa packages? I am using 
~/.emacs.d from previous installation and M-x package-list-packages 
shows that there are packages to be upgraded but trying to type "Ux" 
breaks Emacs.

TIA,
 Angelo.
