temp Vandium just gives error can not find ip adress to website while the same websites works perfectly on other devices with same wifi.
Are you using a VPN, private DNS, or any content blocker of any kind? Trying to download with Tor/Orbot running might also cause issues. If you are using any of those, try disabling them in the Owner profile and try opening a web page with Vanadium again. If the page loads, then try the updater again.
If that suggestion doesn't apply or doesn't work, then...
temp Another user reporting same or similiar issue
Yes, the discussion is here this post and based on what you're saying it sounds like it may be the same issue, but it's best to confirm with logs first. Can you get logs from the updater app, app.seamlessupdate.client
to confirm you have the same error: onPayloadApplicationComplete: 20
?
You can do that from the Owner profile in Settings > Apps > All apps > *show system in upper right-hand corner* > System updater > View logs
.
