`do-release-upgrade` is selecting 17.10 instead of 18.04

Question

There was a bug fix awhile back for this problem: `do-release-upgrade` selects 18.04 instead of 17.10 target. My problem is the opposite of this bug fix.

On my test partition when I try to upgrade 16.04 to 18.04 and I run:

~$ sudo do-release-upgrade
Checking for a new Ubuntu release
Get:1 Upgrade tool signature [819 B]                                                       
Get:2 Upgrade tool [1,253 kB]                                                              
Fetched 1,254 kB in 0s (0 B/s)                                                             
authenticate 'artful.tar.gz' against 'artful.tar.gz.gpg' 
extracting 'artful.tar.gz'

It is selecting Artful (17.10) and not Bionic (18.04).

If I change /etc/update-manager/release-upgrades last line from:

Prompt=normal

to:

Prompt=lts

and rerun do-release-upgrade I get this:

$ sudo do-release-upgrade
Checking for a new Ubuntu release
No new release found.

Assuming 18.04 has been properly populated into Canonical Repositories, what am I doing wrong???

Answer 1

It's normal; it will take some time before the new release is offered that way.

If you want to do it now, try:

do-release-upgrade -d
