Bug description

I have been trying for two days now to install the automatic update of Nextcloud Desktop. Every time I restart my laptop, it tells me that the update has failed. However, when I click “Check now” in the settings under the update channel, it says that the latest version is already installed (4.0.4).

Steps to reproduce

1. Install version 4.0.4 and activate automatic update
2. Restart your device
3. Automatic update failed

Expected behavior

The update should not fail.

this is an already known issue
sorry for that
it was fixed by #9350
it is part of the already published 4.0.6
we also changed the way we distribute updates to hopefully provide the update correctly if you retry

@mgallien When is the update available with the stable automatic desktop client updater?

@mgallien When is the update available with the stable automatic desktop client updater?

I think what @mgallien says that 4.0.6 version already solves this bug. So download the new version from the website and install it manually and this will resolve the auto update . Since I started using the client a year ago. I always worked properly.

same issue here. changed the update channel to "beta". Nextcloud Client 4.0.6 is offered and downloaded. "Restart and update" results in the same error "A new version of the Nextcloud CLient is available but the updating process failed"

yeah manually installing 4.0.6 worked. I'm afraid a lot of ppl will be soft-locked from nextcloud autoupdate tho :( across all my devices 4.0.5 is what's suggested by default, and you can't jump straight to 4.0.6

[mgallien]

we are sorry for the trouble but once a broken release assets has been downloaded, the 4.0.4 or 4.0.5 will require a manual update
we have no other way to solve this issue
now we modified the distribution of update to 4.0.4 and 4.0.5 such that this issue is prevented and the root cause is fixed in 4.0.6 release
