External Email - Use Caution        

Hello Tristan,
I can send you an email directly later today with some tests you can try for 
freeview and some other commands  If the test succeeds, then at least it 
would mean your environment is good.
The original bug report on the Arch Linus page - while listing  a signal 
11 - did not look to me like it was not from the same cause as what you 
subsequently posted.  That error was detecting a divide by zero (before it 
happened) in the hardware from some calculation which I take to mean the loader 
had previously found everything it needed to load the binaries into memory and 
run them.
BTW - the 7.1.0 binaries on the download page should work on CentOS8 if you 
have that OS to try.

- R.

a quick follow up, I've now been able to find my issue in the wild as well (not 
just on my own machines). I use Arch Linux personally and on a small 
handful of workstations professionally, and when investigating using FS on 
Arch, I stumbled upon an AUR build someone had done. While I didn't intend to 
use this buildfile (still version 6.x), the top comment on the below link 
alludes to the same PETSC error message with FS as I'm experiencing on my

- Use Caution        Hello 
Tristan,Going back to that thread, I’d like to try the command you uploaded 
data for as freesurfer_data.tar.gz on a couple of Ubuntu systems, but 
either I’m looking in the wrong place or it’s not there anymore.  Is there 
a shared google drive link or something you point me to for a download 
link? > freeview -v brainmask.mgz T1.mgz -f lh.white:edgecolor=yellow

all.The issues I'm having are the same as they were in my prior thread, found 
here:MailScanner has detected a possible fraud attempt from

be https://www.mail-archive.com/freesurfer@nmr.mgh.harvard.edu/msg63458.htmlI
 tried everything up to and including compiling everything from scratch 
(including FS itself, missing libs, PETSC, etc.). The main takeaway is 
that I pretty convincingly narrowed the issue down to PETSC+Ubuntu 18.04, the 
most pertinent details for that being in the following 
post:https://www.mail-archive.com/freesurfer@nmr.mgh.harvard.edu/msg63702.htmlBack
 when I was active in that thread, I emailed the PETSC mailing list and got no 
response, and at the time I was pretty busy with other projects so I had to let 
it go for the time being; I maintained my old RHEL6 server so people could 
continue to use FS. Now with everyone in quarantine (and RHEL6 entering ELS 
this November), it's a decent time to look back into this issue. I 
wouldn't have reached back out to the FS list, however when I saw that a focus 
was being placed on Ubuntu (and that there was a working Ubuntu VM), I became 
hopeful that maybe this issue was 
resolved?TFrom: fsbu...@contbay.com <fsbu...@contbay.com>Sent: Tuesday,

Ubuntu (was FreeSurfer V 7.0 on Centos 8) We would also like to know about 
any issues you are seeing on Ubuntu.I think Ubuntu eliminated some jpeg/png 
packages from their repos.  Those can be downloaded and installed 
manually,e.g., libpng12-0_1.2.54-1ubuntu1.1_amd64.deb, 
libjpeg62_6b2-3_amd64.deb.  That is part of the reason we made an Ubuntu 
18 VM available with everything pre-installed. The VM is essentially what 
has been used for the freesurfer course which runs mostly freeview commands 
with some mri* commands (though I believe a recon-all also works).  The VM 
is running binaries built on CentOS7 - as the reference platforms for 
freesurfer dev are currently CentOS and MacOS.  We are looking at making a 
.deb installer for freesurfer on Ubuntu though.There is some info on the wiki 
about packages required to compile the source on Ubuntu - but you don’t need 
all of these to run (even the CentOS) binaries.MailScanner has detected a

       Is there going to be an "official" 
Ubuntu build this time around (as in, built and tested in Ubuntu) that isn't 
the VM? Both the current CentOS and the dev builds continue to have issues 
(even when compiled from scratch) on my Ubuntu 18.04 
servers.Thanks!T________________________________From:

FreeSurfer V 7.0 on Centos 8       External 
Email - Use CautionHello Mina,I see from 
https://www.centosblog.com/centos-eol-dates/ that CentOS 6 will no longer be 
updated as of 11/2020, and similarly for CentOS 7 in 6/2024.  It looks 
like CentOS 8 was released around September of 2019.While we do not currently 
build/test on CentOS8, I am sure it will eventually be supported. 
  Given some users will continue to use CentOS 6 even after 11/2020 
and that many people have been running the freesurfer 6 release on CentOS6, 
then even the upcoming freesurfer 7 release is targeting CentOS6, CentOS7 and 
Ubuntu linux (as well as Mac OS).There is also currently an Ubuntu 18 VM with 
freesurfer 6 and the beta release of freesurfer 7 pre-installed which you can 
find here, https://surfer.nmr.mgh.harvard.edu/fswiki/VM_67- R.On Mar 30, 2020,
