Bug description

When I start Nextcloud Desktop v3.14, it doesn't work. Nothing happens. The following error appears in the CLI:

Failed to initialize instances shared memory:  "QSharedMemory::handle: doesn't exist"
QGuiApplication::setDesktopFileName: the specified desktop file name ends with .desktop. For compatibility reasons, the .desktop suffix will be removed. Please specify a desktop file name without .desktop suffix
nextcloud.gui.application: Migrating old config from "/home/jvt038/.local/share/Nextcloud" to "/home/jvt038/.config/Nextcloud"
nextcloud.gui.application: Failed to move the old config directory to its new location ( "/home/jvt038/.local/share/Nextcloud" to "/home/jvt038/.config/Nextcloud" )
nextcloud.gui.application: Will move the individual files QList("Nextcloud_sync.log")
nextcloud.gui.application: Fallback move of  "Nextcloud_sync.log" also failed
Aborted (core dumped)

Nextcloud 3.13.3 still works though.

Additional info

I have enabled experimental features to have VFS-support on Linux.

[SebiAi]

I have the same issue on Linux Mint 21.3.
Don't know if the VFS (extension system) has something to do with it - I have it enabled.

[gpl-ajackson]

I have this same issue on Ubuntu 24.04.

[mgallien]

I can confirm.
Some binary resources needed by webengine are missing.
sorry

[jacek-kubek]

I can confirm the same bug: Debian 12 (bookworm) - several systems (machines) - with and without VFS.
Appimage 3.13.4 works without this issue (downloaded from /desktop/releases/Linux).

[xcablex]

I can confirm as well (Mint 20.2).
Starting from the terminal I get a list of missing GLIBC_2.32-35 error

I have the same "Failed to initialize instances shared memory: "QSharedMemory::handle: doesn't exist"

[xopxe]

Same with a standard Ubuntu 22.04

[voggur]

Rollback to 3.13.4-1 and it works again

[wchouser3]

I can confirm. Linux Mint 22 - same errors and wont start

[camilasan]

Fixed with #7167
You can try this build: https://cloud.nextcloud.com/s/McHcTm43sszwj7R - it is only for testing ⚠️

[JVT038]

@camilasan the issue has not been fixed for me on 3.14.1 or your test build. The same error still exists with the same error messages.

[Appryhandsome]

Been facing the same problem for a few weeks now. Unable to use the nextcloud client installed on Arch via yay.

The fix will only be present in our AppImage.

[camilasan]

The same error still exists with the same error messages.

Some of the error messages are not related to crash. Does it still crash?

[JVT038]

Yeah, the appimage for version 3.14.1 still crashes, with the following logs:

QGuiApplication::setDesktopFileName: the specified desktop file name ends with .desktop. For compatibility reasons, the .desktop suffix will be removed. Please specify a desktop file name without .desktop suffix
nextcloud.gui.application: Migrating old config from "/home/jvt038/.local/share/Nextcloud" to "/home/jvt038/.config/Nextcloud"
nextcloud.gui.application: Failed to move the old config directory to its new location ( "/home/jvt038/.local/share/Nextcloud" to "/home/jvt038/.config/Nextcloud" )
nextcloud.gui.application: Will move the individual files QList("Nextcloud_sync.log")
nextcloud.gui.application: Fallback move of  "Nextcloud_sync.log" also failed

Furthermore, using the temporary appimage you provided in this issue (Nextcloud-bugfix-appimage-x86_64.AppImage), the following error occurs (and the appimage still crashes)

Failed to initialize instances shared memory:  "QSharedMemory::handle: doesn't exist"
QGuiApplication::setDesktopFileName: the specified desktop file name ends with .desktop. For compatibility reasons, the .desktop suffix will be removed. Please specify a desktop file name without .desktop suffix
