Windows 10: HYPER-V Windows 10 Ubuntu 18.04 cannot update

I have been running Ubuntu 18.04 on Windows 10 (64bit 1903 fully patched) without problems, save that any attempt to update to 19.04 fails - crashes after Fetching completed

; > doPostInitialUpdate

; > quirks: running discoPostInitialUpdate

; > running Quirks.discoPostInitialUpdate

: > abort called

Ubuntu is desktop version and was installed from iso image.


Any suggestions as how I can update / find out where the problem lies?


I have posted this on ubuntu forums but so far no answers. I know I can install a 19.04 VM from scratch, but I would prefer to update if possible.

Microsoft to make Ubuntu 18.04 a First class VM with HYPER-V

This link has more details (steps to do it are for version 16.04 - 18.04 is slightly easier)

Here is how to do it for 18.04. Works on SCU

NOTE: 18.04 is not yet officially issued for a couple of week or so. Above guide uses the daily prerelease builds.

That looks really cool. I am glad it worked ok. I had guide working for a pre-release of 18.04 but something changed on release version, and it fell over.

Others on github site had same issue and eventually a user posted a solution (commenting out two lines in install.sh) and I got guide working.

Interestingly, one of the guys there linked to my guide, presumably as it is more upto date than original 16.04 guide -LOL!

I also get that error message (partly hidden in second screen shot) but I dismiss it and nothing seems to be affected.
