This error is preventing any communications with RHN satellite 5.6 as well.
(In reply to lau18 from comment #1) > This error is preventing any communications with RHN satellite 5.6 as well. Does anyone know when this defect will be resolved? With the "plugin" failure, it's preventing dnf command to perform packages retrieval/update via RHN satellite. Thanks.
Fixed in upstream via commit 3579da38e2efb88cec0f6c5f7f6054b9274a095d 1259884, 1286555 - make octal numbers python3 compatible commit ab6e4863537fcce975939872f9daa45979eec65a 1259884, 1286555 - recover from python3 pickle error when runing back in python2 ... commit 9aad1b15b32fbe877288636bc8dd312bd644a028 1259884, 1286555 - build python3 version of rhnlib commit 559ac8941e7e8f09599a168cc5fc706ac2779f10 1259884, 1286555 - use python3 compatible print syntax
Any idea of when these fixes are ready for public use?
Updated development packages are in nightly repos (http://yum.spacewalkproject.org/nightly/).
Thank you, Michael. Would you provide advice to resolve below package update issues. Current versions on my system for these three packages are following: dnf-plugin-spacewalk-2.4.15-1.fc23.noarch rhn-client-tools-2.4.5-2.fc23.noarch rhnlib-2.5.75-2.fc23.noarch Downloaded the latest packages from spacewalkproject.org and got below dependency error on python3-rhnlib, which google couldn't find any reference to it.

I see. I've forgotten to update comps for Fedora 23 client to push python3-rhnlib there. It's been fixed and package should land in the repo sometime today. In the meanwhile you can download it directly from koji: http://koji.spacewalkproject.org/koji/buildinfo?buildID=42621

Thanks.
To clarify the source of the rhnlib* rhn-client*. rhnlib was from koji and rhn-client-tool* from http://yum.spacewalkproject.org/nightly/. Is there a newer version of rhn-client-tools somewhere else?
Michael, Please ignore the previous two comments that I made as I didn't see the python3-rhnlib at koji link until now. I'll test the package tomorrow and keep you posted of the result.
The dependency error seems to have been resolved by including python3-rhnlib as a part of the "dnf" installation. However, registering with Red Hat satellite server with "rhnreg_ks" (subset of rhn-setup-2.5.8-1.fc23.noarch pkg) is partially failed where it would register with satellite (systemid and up2date are generated) but unable to access channels that are mapped to the "activationkey". Here is the debug-output with the "Invalid function call" error: [root@daemon2 ~]# /usr/sbin/rhnreg_ks -vvv --force --norhnsd --activationkey=4-fedora-23-x86-64 D: rpcServer: Calling XMLRPC registration.welcome_message D: opening db environment /var/lib/rpm cdb:0x401 D: opening db index /var/lib/rpm/Packages 0x400 mode=0x0 D: locked db index /var/lib/rpm/Packages D: rpcServer: Calling XMLRPC registration.welcome_message D: opening db index /var/lib/rpm/Providename 0x400 mode=0x0 D: rpcServer: Calling XMLRPC registration.new_system D: rpcServer: Calling XMLRPC registration.welcome_message D: rpcServer: Calling XMLRPC registration.add_hw_profile D: rpcServer: Calling XMLRPC registration.welcome_message D: rpcServer: Calling XMLRPC registration.add_packages D: opening db environment /var/lib/rpm cdb:0x401 D: opening db index /var/lib/rpm/Packages 0x400 mode=0x0 D: loading keyring from pubkeys in /var/lib/rpm/pubkeys/*.key D: couldn't find any keys in /var/lib/rpm/pubkeys/*.key D: loading keyring from rpmdb D: opening db index /var/lib/rpm/Name 0x400 mode=0x0 D: read h# 1939 Header SHA1 digest: OK (44dfac3a3ed2ad52f6139c5313da593614f56803) D: added key gpg-pubkey-34ec9cba-54e38751 to keyring D: read h# 1940 Header SHA1 digest: OK (683edfac165623e8dbc0b62f22e18dc035e03c41) D: added key gpg-pubkey-863a853d-4f55f54d to keyring D: read h# 1941 Header SHA1 digest: OK (b8e59da323c210f9554a1c1dffc3d9b901a2e142) D: added key gpg-pubkey-b3516aa3-40e58259 to keyring D: read h# 1942 Header SHA1 digest: OK (eec341e72036967f588a1b3cbe7cbf8340842eea) D: added key gpg-pubkey-26c2112f-43ea6bde to keyring D: read h# 1943 Header SHA1 digest: OK (f59550c9f7e74d25fb1171b7f1bc15d966d06b40) D: added key gpg-pubkey-f6777c67-45e5b1b9 to keyring D: Using legacy gpg-pubkey(s) from rpmdb D: opening db index /var/lib/rpm/Providename 0x400 mode=0x0 D: closed db index /var/lib/rpm/Packages D: closed db index /var/lib/rpm/Providename D: closed db index /var/lib/rpm/Name D: closed db environment /var/lib/rpm Warning: yum-rhn-plugin is not present, could not enable it.D: opening db environment /var/lib/rpm cdb:0x401 D: opening db index /var/lib/rpm/Packages 0x400 mode=0x0 D: locked db index /var/lib/rpm/Packages D: opening db index /var/lib/rpm/Providename 0x400 mode=0x0 D: do_call packages.checkNeedUpdate('rhnsd=1',){} D: Attempt to call an unsupported action packages.checkNeedUpdate('rhnsd=1',) D: local action status: (6, 'Invalid function call attempted', {}) D: rpcServer: Calling XMLRPC registration.welcome_message D: closed db index /var/lib/rpm/Packages D: closed db index /var/lib/rpm/Providename D: closed db environment /var/lib/rpm D: closed db index /var/lib/rpm/Packages D: closed db index /var/lib/rpm/Providename D: closed db environment /var/lib/rpm
Michael, Also, before enabling the dnf-plugin-spacewalk, command "dnf repolist" returns nothing, no output. However, after setting enable=1 in /etc/dnf/plugins/spacewalk.conf, it caused the same Traceback on both "dnf repplist" and "dnf update" commands as shown below. Should I NOT enable the dnf-plugin-spacewalk?

Comment 18: I received same traceback and wrote patch for this: https://github.com/spacewalkproject/spacewalk/pull/339
Thank you, Pavel. When dnf-plugin-spacewalk is enabled, I also see the same Traceback as in your comment 11 using rhn-check and rhn-profile-sync: [root@daemon2 tmp]# rhn-profile-sync Traceback (most recent call last): File "/usr/sbin/rhn-profile-sync", line 23, in <module> from up2date_client import up2dateAuth File "/usr/share/rhn/up2date_client/up2dateAuth.py", line 14, in <module> from up2date_client import clientCaps File "/usr/share/rhn/up2date_client/clientCaps.py", line 9, in <module> from up2date_client.capabilities import parseCap File "/usr/share/rhn/up2date_client/capabilities.py", line 3, in <module> from up2date_client import up2dateErrors File "/usr/share/rhn/up2date_client/up2dateErrors.py", line 54, in <module> from dnf.exceptions import Error as PmBaseError ImportError: No module named dnf.exceptions When will your fix on up2dateAuth.py make it in the next version of rhn-client-tools-2.5.8-1.fc23.noarch package? In other words, when will I be able to get it from the nightly repos (http://yum.spacewalkproject.org/nightly/)?

Michael, Using the latest versions of dnf-plugin-spacewalk-2.5.3-1 rhnlib-2.5.82-1 rhn-client-tools-2.5.9-1, rhnreg_ks failed with missing module. The same command was working with the previous versions of the packages after manually applied the fix in up2dateAuth.py per Pavel suggested in Comment 19: [root@daemon2 tmp]# /usr/sbin/rhnreg_ks --force --norhnsd --activationkey=4-fedora-23-x86-64 Traceback (most recent call last): File "/usr/sbin/rhnreg_ks", line 37, in <module> from up2date_client import rhnreg File "/usr/share/rhn/up2date_client/rhnreg.py", line 16, in <module> from up2date_client import rhnserver File "/usr/share/rhn/up2date_client/rhnserver.py", line 34, in <module> from rhn.tb import raise_with_tb ImportError: No module named 'rhn.tb'
Do you have latest version of all packages? [root@fedora ~]# rpm -q dnf-plugin-spacewalk rhnlib python3-rhnlib rhn-client-tools rhn-check rhn-setup rhn-setup-gnome dnf-plugin-spacewalk-2.5.3-1.fc23.noarch rhnlib-2.5.81-1.git.36.2ac5a69.fc23.noarch python3-rhnlib-2.5.82-1.fc23.noarch rhn-client-tools-2.5.9-1.fc23.noarch rhn-check-2.5.9-1.fc23.noarch rhn-setup-2.5.9-1.fc23.noarch package rhn-setup-gnome is not installed With the above packages it works for me [root@fedora ~]# /usr/sbin/rhnreg_ks --force --norhnsd --activationkey 3-fedora23-x86_64 Warning: information about network interfaces could not be retrieved on this platform. [root@fedora ~]# rhn-channel -l fedora23-x86_64
I have all but python3-rhnlib-2.5.81-1.fc23.noarch.rpm because I couldn't find version 2.5.82-1 on neither nightly nor koji sites.
http://yum.spacewalkproject.org/nightly-client/Fedora/23/x86_64/python3-rhnlib-2.5.82-1.fc23.noarch.rpm
Hi Michael, The repository nightly-client doesn't contain package rhnlib and this package is needed for work others apps, which are written for python2. For example rhncfg-.. http://yum.spacewalkproject.org/nightly-client/Fedora/23/x86_64/ The repository contains only package python3-rhnlib
With the version 2.5.82-1 of python3-rhnlib, rhnreg_ks worked correctly. With the dnf-plugin-spacewalk enabled, I could see satellite channels and update packages. I have to manually update the /etc/dnf/plugin/spacewalk.conf to enable it. Shouldn't the default be enabled (i.e. enabled = 1)? One problem appeared as I executed rhn-channel: [root@daemon2 plugins]# rhn-channel -l An error has occurred: <class 'TypeError'> See /var/log/up2date for more information [Thu Jan 21 13:44:15 2016] up2date Traceback (most recent call last): File "/usr/sbin/rhn-channel", line 242, in <module> main() File "/usr/sbin/rhn-channel", line 226, in main list_channels() File "/usr/sbin/rhn-channel", line 203, in list_channels for channel in sorted(channels): <class 'TypeError'>: unorderable types: rhnChannel() < rhnChannel() [Thu Jan 21 13:44:54 2016] up2date Traceback (most recent call last): File "/usr/sbin/rhn-channel", line 242, in <module> main() File "/usr/sbin/rhn-channel", line 226, in main list_channels() File "/usr/sbin/rhn-channel", line 203, in list_channels for channel in sorted(channels): <class 'TypeError'>: unorderable types: rhnChannel() < rhnChannel() Thanks.
Any update on the rhn-channel traceback?
I installed package rhn-setup-2.5.10-1.fc23.noarch and rhn-channel works # dnf install http://yum.spacewalkproject.org/nightly-client/Fedora/23/x86_64/spacewalk-client-repo-2.5-3.fc23.noarch.rpm (enable nightly repo) # dnf install rhn-setup # rhn-channel -l fedora-23-x86_64
Still see the same TypeError after configured the nightly repo. Here is a list of rpm from the repo that are installed on the system: [root@daemon2 yum.repos.d]# rpm -qa|egrep "rhn|spacewalk" rhn-setup-2.5.10-1.fc23.noarch rhn-check-2.5.10-1.fc23.noarch spacewalk-client-repo-2.5-3.fc23.noarch dnf-plugin-spacewalk-2.5.3-1.fc23.noarch rhnlib-2.5.83-1.fc23.noarch rhnsd-5.0.18-1.fc23.x86_64 rhn-client-tools-2.5.10-1.fc23.noarch python3-rhnlib-2.5.83-1.fc23.noarch Is one of the rpms out of date or I need to installl more packages?

Same TypeError still there after removing the rhnlib-2.5.83-1.fc23.noarch. Where is "brew" for getting the latest rhnlib? Thanks.
Could the error be that the fact my fc23 is registered with an RHN Satellite 5.6 and you might be talking to a different content server?

Pavel, Not quite sure how to interpret your last comment. Does it mean you have fixed the "TypeError" or you now see the error? As for the patch that fixed the "/dev/tty", what rpms will I require for the fix?
Issues from comment #36 and #37 fixed in commit b1a12fc6a395cfc61c4c73f0476c7cf3e7ae4221 1259884 - fixed missing method for sorting commit e6ad99c0f23187cf50036d967ffb94eddd411bab 1259884 - open terminal for write only
The "rhn-channel -l" is working after updated below three packages on my system: rhn-check-2.5.11-1.fc23.noarch.rpm rhn-setup-2.5.11-1.fc23.noarch.rpm rhn-client-tools-2.5.11-1.fc23.noarch.rpm Unlike Pavel's example, rhn-channel -L would prompt for user name and password and then didn't output any available channel data: # rhn-channel -L -v Username: lau18 Password: # Other than that, everything seems to be working. Thanks.
I tested Fedora 24 as Spacewalk client: installation of rhn-setup ok registration to SW, activation key ok dnf repolist, dnf install from sw repo ok we know that dnf has some troubles with spacewalk eg. bz1236609 rhn-channel -l, -L, -a , -r ok rhncfg-client diff, get, list, verify ok rhn-actions-control ok rhn-profile-sync ok rhn_check ok spacewalk-abrt produces AVC error - created bug bz1398376 otherwise works osad service does not start - AVC bz1397333 works in permissive mode I tried to retest all issues mentioned in previous comments - and it looks ok issues what I hit are tracked in separate bzs VERIFIED
