[Bug 1509081] Re: nano segfaults as root after upgrade to 15.10

Then please click at the top of this page that you are affected too.

> Could you please provide patch's URL

You can find the patch somewhere on the right.  But this is the direct
URL:

https://bugs.launchpad.net/ubuntu/+source/nano/+bug/1509081/+attachment/4513318/+files
/trim-an-overlong-hostname.patch

> and how-to install ?

No.  You will have to google how to get the source, apply the patch,
compile, and install.  Or wait for Ubuntu to apply the patch and push it
out.  Or change your hostname to something shorter.  Or comment out the
"set locking" in your /etc/nanorc file.

Title:
  nano segfaults as root after upgrade to 15.10

Status in nano package in Ubuntu:
  Confirmed

Bug description:
  Description:	Ubuntu 15.10
  Release:	15.10

  nano:
    Installed: 2.4.2-1
    Candidate: 2.4.2-1
    Version table:
   *** 2.4.2-1 0
          500 http://mirror.bytemark.co.uk/ubuntu/ wily/main amd64 Packages
          100 /var/lib/dpkg/status

  
  After upgrading Ubuntu 15.04 to 15.10, when I run nano as root on a file it just segfaults. I'm not having this problem on other 15.04->15.10 upgrades

  strace is https://p.defau.lt/?q7xGwt3HoqB74xTawUUHDA
  catchsegv is https://p.defau.lt/?0SPQY_bDj6F6j1ZKeToQoA

  
  Under gdb with nano-dbgsym installed, it gives

  #0  main (argc=2, argv=0x7fffffffe688) at ../../src/nano.c:2768

  
  If I run it as sudo nano filename.txt, it gives an error as below rather than segfaulting

  [ Couldn't determine hostname for lock file: File name too long ]


  Both my user and root have the same locale settings. I've tried
  regenerating the locales
