[LON-CAPA-admin] LON-CAPA version 2.11.3

Hello HK,

CentOS 7 reaches end of life on June 30, 2024
CentOS 8 reaches end of life on December 31, 2021

After the end of 2021, CentOS 8 will be transformed from being a downstream community rebuild of Red Hat Enterprise Linux into an upstream (development) branch of Red Hat Enterprise Linux (RHEL), called CentOS 8 Stream (reaches end of life on May 31, 2024).  See: www.centos.org/centos-stream/ 

If you prefer *not* to run your LON-CAPA production instance on a development branch of RHEL (i.e., CentOS Stream) in 2022 then you could choose to:

(a) keep your LON-CAPA nodes on CentOS 7 until 2024
(b) migrate your LON-CAPA nodes to RHEL 8
(c) migrate your LON-CAPA nodes to another Linux distro with long term support, e.g., Ubuntu, SLES, or Oracle Linux.

As regards the "not found" messages, that is most likely the result of your email server's URL Defense service rewriting links in emails which you receive from this mailing list.

You might visit the web archive of my post to this list:

and copy and paste the unmodified URLs for the wget commands from there.

You can also download the compressed archive file for 2.11.3 from:

If you extract the contents you will find the same release notes (with unmodified URLs) in the README file included with the release.

Another possibility is that your domain name service is not resolving the IP address for install.loncapa.org or install.lon-capa.org.

Hi Stuart,

Thanks for the update. Looks like lots of fixes and improvements. A few questions.

  1.  What is the story with Centos 8? Heard that it is not going to be supported past end of this year but will have a different "path" for updates. Kind of baffled what is going on.
  2.  Going through the steps of updating, I got a couple of events not found messages.

[www at tycho]$ sudo rpm --import https://urldefense.com/v3/__http://install.loncapa.org/versions/centos/RPM-GPG-KEY-loncapa__;!!PhOWcWs!lvoMVqpbJBQDvutS_D1xLmX-u-_ZBIlBqDCGcQ15cgtqgxbIVKeAwaLnzqA$
-bash: !lvoMVqpbJBQDvutS_D1xLmX-u-_ZBIlBqDCGcQ15cgtqgxbIVKeAwaLnzqA$: event not found

The rpm -q reports
[www at tycho]$ sudo rpm -q gpg-pubkey --qf '%{VERSION}\t%{SUMMARY}\n' |grep LON
c11f2266 gpg(LONCAPA Academic Consortium (Package signing) <certificate at loncapa.org>)

Seems to work but result is slightly different from the instructions.

[www at tycho]$ wget https://urldefense.com/v3/__http://install.lon-capa.org/versions/loncapa-2.11.3.tar.gz__;!!PhOWcWs!lvoMVqpbJBQDvutS_D1xLmX-u-_ZBIlBqDCGcQ15cgtqgxbIVKeABHnAqrs$
-bash: !lvoMVqpbJBQDvutS_D1xLmX-u-_ZBIlBqDCGcQ15cgtqgxbIVKeABHnAqrs$: event not found

The wget fails - nothing is downloaded.
