Still can't upgrade? Is there a new delay? [duplicate]
Firstly, as mentioned in other questions:
- LTS upgrades don't occur until the first point release. This is because Canonical prefers to let things settle before sending the release to automatically upgraded systems - usually servers, and usually in HUGE numbers, which will have an effect not just on Canonical's server load but also on SysAdmins worldwide and Canonical's support team.*
- Automated server installs occur during the period after a point release and before an upgrade. These are smaller numbers of servers but still significant compared to numbers before the point release.**
However, more importantly, from gleaning the URL do-release-upgrade calls and its content, I suspect the LTS upgrade list is not architecture-specific, and also from the current list of open bugs against the 18.04.1 point release some of those bugs are specific arch bugs.
Needless to say, it's in Canonical's interest to release when these things work and not sooner.
Patience is a virtue. :-)
* Take it from a SysAdmin, you can be up for days fixing little kinks when this happens, so you want to be damn sure it goes smoothly.
** SysAdmins are a cautious bunch, so we don't tend to put even LTS first cuts into production, but we will push LTS to new installs after the first point release
