EPEL-5 article appearing on FedoraMagazine.org

So I thought I was not writing anything more about the EOL of EPEL-5, but I got asked by several people why no one had written anything about it 😐. The ability of my posts to reach the world was much smaller than I realized. In order to rectify that a bit, here is another article on the EOL of EPEL-5 this time at Fedora Magazine.

IMPORTANT REMINDER: EL 5 is EOL on March 31. 2017

This is probably my final reminder on this before April 3rd 2017. As listed at https://access.redhat.com/support/policy/updates/errata and https://en.wikipedia.org/wiki/Red_Hat_Enterprise_Linux#Product_life_cycle Red Hat Enterprise Linux will be exiting "Production Phase 3", and CentOS will be archiving off old EL-5 releases.

At that point, all remaining EPEL-5 packages will be archived to /pub/archive/epel/5 for systems to get data from. No new updates or packages will be done after that.

Trying to get an idea about what packages are used

Background

One of the questions I get asked a lot is "You provide various statistics for Fedora, can you show which packages are installed the most?"

To head off a lot of future requests, the answer is no, no I can't. We do not have any sort of popcorn database which shows what packages are popular. When a user requests the OS to install a package, there is no "Hey I am asking for Bob if I can install libfoobar" that gets sent to the Fedora servers. What yum, dnf, PackageKit, or Salt do is then request for the repo data, looks to see if there is a way to figure out what is wanted and then asks for any packages that it needs to get.

It is this data that I can sort of glean some sort of idea of most installed packages.. but I feel it is way past "Lies", "Damn Lies", and "Statistics" into regions like  "Political Promises" or "Half Life 3 confirmed". Looking over an entire month of requests, sorting the data, and ranking the requests, I find that a bunch of packages show up a lot while others fall off in a long tail. Things that make this data dirty are the fact that if 200 people ask for wordpress, 150 for mediawiki and 90 for nagios.. I will see various PHP trunk packages that all three want as a higher number. I can't simply tell if the person wanted that PHP package by itself or wanted wordpress. [I could possibly try and work out a transaction of requested packages and figure out what nodes and leafs there might be.. but I found that the tools don't always request from download.fedoraproject.org everything it is wanting because it possibly already 'knows' where something is.

In any case, here are the most requested packages to the download website for January.

EPEL-7

  1. epel-release-7-9
  2. python2-pip-8
  3. python2-boto-2
  4. openvpn-2
  5. php-tcpdf-6
  6. php-tcpdf-dejavu-sans-fonts-6
  7. pdc-updater-0
  8. duplicity-0
  9. nagios-plugins-2 *lots of plugins show up here*
  10. ansible-2
  11. libopendkim-2
  12. opendkim-2
  13. cowsay-3
  14. python2-wikitcms-2
  15. pkcs11-helper-1
  16. fedmsg-0
  17. htop-2
  18. munin *lots of munin packages here
  19. awscli-1
  20. hdf5-1

EPEL-6

  1. nagios-plugins-2 *lots of other nagios removed*
  2. libmcrypt-2
  3. nodejs-0 *lots of other nodejs removed*
  4. python2-boto-2
  5. GeoIP-1 *other GeoIP removed*
  6. geoipupdate-2
  7. nrpe-2
  8. libnet-1
  9. denyhosts-2
  10. eventlog-0
  11. syslog-ng-3
  12. epel-release-6-8
  13. php-pear-Auth-SASL-1
  14. php-pear-Net-SMTP-1
  15. php-pear-Net-Socket-1
  16. perl-Net-IDN-Encode-2
  17. perl-Net-Whois-Raw-2
  18. perl-Regexp-IPv6-0
  19. pwhois-2
  20. v8
EPEL-6 is our most popular distribution with a ratio of about 12 EPEL-6 : 7 EPEL-7: 1.5 Fedora 25 to 1 EPEL-5 request over the month of January. 

EPEL-5

  1. R-core-3 *lots of other R packages removed*
  2. globus-gssapi-gsi-devel-12 *lots of other globus removed*
  3. nordugrid-arc-5
  4. xrootd-client-libs-4 *lots of other xrootd removed*
  5. pcp-libs-devel-3
  6. nordugrid-arc-devel-5
  7. libopendkim-2
  8. libopendmarc-1
  9. pcp-libs-3
  10. nordugrid-arc-plugins-globus-5
  11. libopendkim-devel-2
  12. libopendmarc-1
  13. ebtree-6
  14. myproxy-libs-6
  15. mosh-1
  16. lua-cyrussasl-1
  17. drupal7
  18. rear-2
  19. clustershell-1
  20. rsnapshot-1
I found it interesting that R was getting pulled in by a lot of computers on EPEL-5. This OS is almost end of lifed, but it looks like systems are still getting provisioned with it.

Fedora 25

  1. java-1
  2. vim-minimal-8
  3. kernel-core-4
  4. libX11-1
  5. perl-libs-5
  6. perl-5
  7. perl-IO-1
  8. perl-macros-5
  9. perl-Errno-1
  10. nss-3
  11. gdk-pixbuf2-2
  12. gtk3-3
  13. audit-libs-2
  14. nss-softokn-freebl-3
  15. libX11-common-1
  16. gdk-pixbuf2-modules-2
  17. libnl3-3
  18. gnutls-3
  19. pcre-8
  20. gtk-update-icon-cache-3
As can be seen from the Fedora 25, there is another problem with my trying to get an idea of packages.. a package getting updated that is installed on a lot of boxes will show up also. 

Conclusions

I really don't think any 'real' conclusions can come out of this other than people really want vim on their Fedora 25 desktops (emacs was way down the list). 😑 I also want to say that we should get an opt-in popcorn for Fedora :).

[Edited: I forgot this part]

This list of agents which get used to pull down packages for EPEL and Fedora was rather interesting. I combined all the yum together as the many different versions kind of polluted the numbers but here are the top agents:


  1. yum
  2. Salt
  3. dnf
  4. Artifactory
  5. python-requests
  6. Debian Apt-Cacher-NG
  7. PackageKit-hawkey
  8. Axel 2.4 (Linux)
  9. Wget
  10. libdnf
  11. curl
  12. urlgrabber
The Salt seems to come from a large number of amazon systems which are installing either epel-release-6 (80% of the time) or epel-release-7 (20% of the time). Nothing else seemed to be 'pulled' from download.fedoraproject.org so it is probably just a config artifact on bootup.

Major update to Nagios in Fedora Rawhide and EPEL-7 [moving to 4.2.4]

After a couple months of work, I have put together an updated package for Fedora Rawhide and EPEL-7 today. I expect it will have some 'problems' and so have moved the needed karma to 4 and am looking for people to test and give it negative karma with feedback for items broken.

I will work on getting those done this week so we can try and have working versions of Nagios for Fedora Server 26 and EPEL. Currently I expect it to need changes to the selinux policies for both and may need some additional work there. I am working through the processes for getting those done.

EPEL-6 will need some more work because the rpmbuild is complaining that it can't make /var/run/nagios for some reason.

Major update to Fedora/EPEL moving to nrpe-3.0.1

The version of nrpe in Fedora has been 2.15 for a very long time while the upstream Nagios group moved to a 3.0 series. With some work and a lot of help from my friends, I have put an updated nrpe into EPEL-testing for EPEL-6 and EPEL-7 and in Fedora Rawhide.

EPEL

I have put the EPEL update karma for this to be 4 versus 3 as I would like some more testing done by people before it gets working. If it gets a lot of negative karma I will pull it and work with upstream to get a working version into EPEL.

Rawhide

This version of nrpe was the 'fun' one. This is due to the fact that the newer OpenSSL does not allow for introspection of various structures which it used to. Working with Tomas Mraz and Patrick Uiterwijk, I believe I have a semi-working version. [A secondary problem was that I had to pull some sslv2 code out because we do not ship with those libraries anymore. I am hoping upstream will come up with a better fix than my hacksaw method.]

Fedora 25

I have not put in an update to Fedora 25 because it is a major update and was not listed as a change request. I am looking through what needs to be done for this, and when I have gotten any approvals needed will publish it to Fedora 25 testing.

Reminder to self: Using Dennet's principles

These last couple of weeks have been a complete emotional and intellectual mess for me. People are arguing to the right of me, to the left of me and everyone seems to have pulled out their favorite purity test to try and prove if someone is good enough to be in their camp.

In trying to come up with clearer axioms to gauge all the various poop-storms without getting into emotives or purity tests, I ran into this article about Daniel Dennet's tools for trying to be a critical thinker. I will report the paraphrase below:

  1. Accept you make mistakes, and then use them to be a better person.
  2. Respect your opponent. 
  3. Beware of "surely" as it is overused as a rhetorical device to avoid critical thinking by assuming something is sure.
  4. Answer rhetorical questions. As with 'surely', using a rhetorical question is a way to avoid thinking about something by being facetious.
  5. Employ Occam's Razor
  6. Employ Sturgeon's Law. 90% of everything is rubbish... [which cuts both ways.] Don't waste your time defending rubbish and don't waste your time attacking it. Work on the 10-20% which isn't.
  7. Avoid deepities... things which are deep and profound but not well defined. [Another way of looking at it is "If it sounds too good to be true, it probably is".] 
Anyway thanks to Jonathan Corbet of lwn.net for reminding me of the Sturgeon's law wikipedia article which lead me to that piece.

Mea Culpa: Fedora Elections

As announced here, here , and here, the Fedora Election cycle for the start of the 25 release has been done. Congratulations on the winners. Now if you notice there were less than 250 voters for any of the elections out of multiple thousand of eligible voters.. I am not one of them.

It is not like the elections were announced before, at the start, or right before they ended. Yet somehow.. I missed everyone of these emails. I caught various emails on NFS changing configurations, proposed changes to Fedora 26 and 27, or various retired packages.. but I completely spaced the elections. I was actually sending an email asking when they would be held when someone congratulated Kevin Fenzi on IRC about winning.

So to the winners of this cycle of elections. Congratulations. To all the people who put in the hard work of running elections (and having run several it is a LOT of hard work), my sincere apologies for somehow missing it.
