[sle-beta] SLES gnome-session-failed for SLES 12sp3 -> 15 via zypper dup

A fresh install, using the Installer ISO and SLP for Packages + SLED / base / desktop_applications, made no difference.

Same result with a vncserver invocation (5901 - not the yast2 enable remote administration port 5900 thing) :

"Connection refused"

"cannot open display".

Nothing to do with firewall and this bz:


as firewall was entirely disabled for this attempt (because there's no Yast2 tool for configuring it yet).

“zypper dup” is not a supported method to upgrade to Major SLE version,
thus not supported to upgrade from SLES 12 SP3 to SLES 15.

This is only supported for Service Pack Migration of a SLE version, and note
even in this case we recommend to use “zypper migration” instead

This is not new with SLE15, the same statement are true for migrating from SLE
11 to SLE 12. cf https://www.suse.com/documentation/sles-12/singlehtml/book_sle_deployment/book_sle_deployment.html#sec.update.sle.methods

Is this zypper dup path bz worthy?

Only gets the GDM up as well - doesn't allow me to login.

VNC session is just black... Is this a Wayland / X-display permissions issue ? Here's the log.
