On little update about this, as always using Unifi Wifi from Ubitiqui fails most of the time, some time the upgrade works, but some time don't.
Normally I use my phone at least to make the firsts upgrade,maybe somebody will find-out the issue but I am not. I will write some post on the unifi forum in order to try to solve this because is a real issue.
I test this, is very time consuming try to update all the shelly but no dissamble, with my phone I was able to update some..
Always work.. is is solved. 
Are you sure it's not releated to your network infrastructure?
In order to validate I'd open a wifi hotspot with a smartphone, then add one of those affected shellies to that wifi and try the update again.
For testing I get some of the shelly with no update to my home.. And happends the same.. but.. I was reading this forum post en german ..
Ok what we have in common the tree of us, (my customer, me and this people of the forum) ok the unifi router Wifi6 LR...
Ok I use my phone as point of access to give internet to the Shelly and disable the wifi access from my unifi6 LR.. reboot, I see the update again I click the update and the update was successfully!!!! at list on my unit of testing...
I need to test this workaround with my customer... but looks good.
sorry to use english I have the same situation. with 35 shellys plus 2, I have installed 45 shelly 2 plus and only 10 upgrade to 0.10.1 the rest are on 0.10.0 beta3
I have the same point of access Unifi6 LR... maybe I will try to use my phone as point of access and see if the issue is related to this access point..
The shelly work great, but there is no option to change the 35 shelly.. :-(.
@ediazrod Any progress on this? Did you contacted support? If yes, can you provide me your ticket id?
Typically support requests some debugging information and I'm keen to check that and see if those are for replacement.
Nop I have 25 shelly with no update at the end, I will open a ticket.
Regards!
Hi,
from thisCode"available_updates":{"stable":{"version":"0.10.1"}}}It seems that this particular device sees that there is an update. What happens if you try with this particular device to initiate an update from it's own embedded web interface? Does it fail?
This happen on the 95% of the shelly 2PM installed,, no update (some of then update ok) but a minor ... The web interface show as update Ok but after of waiting 5 minutes no update..
I get some of the shelly 2 pm reset , and conect using a cable a very near point of access.. 2 meters, I connect to the wifi, check if go to the cloud, ok, but no update....
{"code":-114,"message":"Resource unavailable: No update info!"}This is the result..
show to the cloud as connected.

Hi I have like 45 shelly 2 PM gen2 installed and I can't install the firmware from 0.10.0 beta3 to 0.10.1 there is any command line to force the upgrade?.
I try to search on http://archive.shelly-faq.de but I don't see the commands for this new version..
