Cannot upgrade SLES 12 SP2 to SP3 or higher

I found 2 entries "Added by SMT registration" on /etc/hosts. I commented out one and now I can connect to smt-ec2.susecloud.net.

However, when prompted for credentials, I provide the user and password found in /etc/zypp/credentials.d but those don't authenticate.

I tried running registercloudguest --force new, with the following result:

/usr/lib/python2.7/site-packages/requests/packages/urllib3/connection.py:264: SubjectAltNameWarning: Certificate for 54.244.244.107 has no subjectAltName, falling back to check for a commonName for now. This feature is being removed by major browsers and deprecated by RFC 2818. (See https://github.com/shazow/urllib3/issues/497 for details.)
SubjectAltNameWarning

I found an old post from February 13, 2017 in which rjschwei explains that the issue was because of memory shortage on the registration servers.

Would someone at AWS take a look into this? Apparently the same issue is happening now.

Thanks

I believe this issue is resolved. Will you please try running the registration again?

I think the registercloudguest issue is solved.

I still see a message:

nwdev:/home/admin # registercloudguest --force-new
/usr/lib/python2.7/site-packages/requests/packages/urllib3/connection.py:264: SubjectAltNameWarning: Certificate for 54.253.118.149 has no subjectAltName, falling back to check for a commonName for now. This feature is being removed by major browsers and deprecated by RFC 2818. (See https://github.com/shazow/urllib3/issues/497 for details.)
SubjectAltNameWarning

But new credentials are available:
nwdev:/home/admin # ls -l /etc/zypp/credentials.d

I will run the Service Packs update a bit later and if successful, document my findings and tag this thread as Answered.

Thank you very much for the registercloudguest fix!!

With the proper SMT registration entry in /etc/hosts and with the command registercloudguest fixed, the upgrade worked perfectly. Also, I found a simpler procedure for SUSE 12, very well documented here:
https://kerneltalks.com/linux/how-to-upgrade-suse-12-sp1-to-sp3-or-sp4/

Briefly:
0.) registercloudguest --force-new
1.) zypper in zypper-migration-plugin
2.) zypper patch
3.) zypper migration
4.) reboot
5.) cat /etc/os-release

Thanks!!!
