Expected behaviour

It should be able to upgrade without wanting to reboot if I select the option that states the same. Or at least after crashing explorer.exe, restart it.

Actual behaviour

It closes nextcloud, crashes file explorer and then demands a reboot anyways, without bringing file explorer or the taskbar back. I have to manually relaunch explorer.exe from task manager.

Steps to reproduce

1. Download the newest available Nextcloud client, while there's another one already configured
2. Install, go for "Close the applications and attempt to restart them"
3. Witness explorer dying and still being asked to reboot your system

Logs

I have no idea how to generate logs for the installer.
Please use Gist (https://gist.github.com/) or a similar code paster for longer
logs.

1. Client logfile:
   Since 3.1: Under the "General" settings, you can click on "Create Debug Archive ..." to pick the location of where the desktop client will export the logs and the database to a zip file.
   On previous releases: Via the command line: nextcloud --logdebug --logwindow or nextcloud --logdebug --logfile log.txt
   (See also https://docs.nextcloud.com/desktop/3.0/troubleshooting.html#log-files)

2. Web server error log:

3. Server logfile: nextcloud log (data/nextcloud.log):

Even if the program is not currently using VFS, and therefore doesn't require to restart Windows Explorer (and doesn't ask to restart it), after restarting the Nextcloud process the pop-up appears.

I clicked "No" and checked the program for the current version, and it was indeed running the updated one, making the reboot unnecessary.

We've got a corresponding ticket already #3551. It's not that easy. The issue is not happening on Windows 11, only on Windows 10.

The fix still isn't implemented.

This is not true, I got this behavior on Windows 11 today with the 3.4.4 installer.

still relevant

Today it installed a new version - this time it rebooted my machine without even asking for permission. It said that it "might be needed to reboot" or something like this, but never explicitly said it is needed to be rebooted with a yes or no option (like in the past).

Seems I am not the only one.

Still not fixed.

I can confirm the unsolicited reboot without any prompt while updating to Desktop Client Version 3.5.2 on Windows 10.0.19044.1766.

[eibex]

This is already tracked at #3551

[claucambra]

This issue has now been fixed in #4566 . Updates for new versions of the client post-3.5.2 should no longer force reboots. I will now close the issue. Thanks all for reporting!

I recently updated to 3.5.4 and observed the exact behavior OP mentioned.

1. Nextcloud Client asks for update and mentions restart necessary
2. Taskbar vanishes and Background gets black
3. Windows is rebooting

3.5.4 was explicitly released to fix this issue -- this means the reboots should stop happening on updates beyond 3.5.4

I'm on version 3.6.1 after upgrading today and I had the same issue as the OP after upgrading to the newer version.

[eibex]

Did you upgrade from 3.6.0 or an older version? 3.6.0 should be fixed.

It asked me to restart but I just pressed No and explorer wasn't crashed (and NC worked just fine even without restarting).
