SUMMARY STEPS TO REPRODUCE 1. Kubuntu 22.04 fresh install (minimum install, fully updated) 2. Connect to a Windows 2012 Server Share via smb://10.0.0.151 in Dolphin 3. Open any file for editing in any editor (Kate, Sublime, LibreWriter), make changes, and save. OBSERVED RESULT With Sublime, get "input/output error"; it can't merge the .part into the file With Kate, get "Could not rename partial file smb://10.0.0.151/shared/file.part" EXPECTED RESULT In previous Kubuntu versions (18.04 through 22.10), got prompted to send the file; and then prompted to overwrite the file. Upon answering yes, it works. SOFTWARE/OS VERSIONS Linux/KDE Plasma: Kubuntu 22.04 (available in About System) KDE Plasma Version: Plasma 5.24.4, KDE Frameworks Version: KDE Frameworks 5.92, Qt Version: 5.15.3 Kernel: 5.15.0-33 ADDITIONAL INFORMATION * I have reproduced this on baremetal and VMs * I have seen other users report this bug in various distros, recently (2021-2022) all "resolved worksforme" or similar, but nothing specifically for Kubuntu * I have checked and have smbclient installed, as well as cifs-utils and nfs-common, as well as kio-fuse. * I notice in older versions (22.10) that when I have Terminal open in these Dolphin SMB locations, it does not show the directory; I'm still in my home / default directory. In 22.04, now it shows me a virtual path of kio-fuse directory. I wonder if that's the critical change?
Kate shouldn't be using kio-fuse, that would only happen for sublime. Moving to kio-extras | samba for now.
open kate with the various variables described here and grab a log please https://community.kde.org/Guidelines_and_HOWTOs/Debugging/Debugging_IOSlaves/Debugging_kio_smb#Reporting_Bugs
This is now working for me with Kate; not sure what changed. However, neither Sublime nor LibreOffice Write work, they still show I/O errors on saving the file. This is no longer a critical bug for me; as such no further debugging / followup will be provided. Feel free to reproduce or close as needed. Thank you for your help in this.
