If you open a file from a sftp server from dolphin you have to specify the username of the connection to open the files. Browsing works just fine. Even though I configured it so I don't have to type any username in ssh config. kioclient exec "sftp://username@homeserver/home/username/example.txt" works kioclient exec sftp://homeserver/home/username/example.txt does not work, though you can browse the files correctly. Opening the file does not yield in any error message other than: kf.service.services: KApplicationTrader: mimeType "x-scheme-handler/sftp" not found STEPS TO REPRODUCE 1. Create Entry in ~/.ssh/config specifying username and hostname 2. Use the "shortcut" in dolphin with sftp://homeserver/home/username/ 3. open file from dolphin OBSERVED RESULT does not open the file EXPECTED RESULT opens the file Linux/KDE Plasma: Fedora Kinoite 39 KDE Plasma Version: 5.27.10 KDE Frameworks Version: 5.111.0 Qt Version: 5.15.11 kio-extras-23.08.4-1.fc39.x86_64 ADDITIONAL INFORMATION just ssh homeserver works relevant entry in ~/.ssh/config Host homeserver HostName myhomeserver.com # domain that points to internal IP of local network User username PreferredAuthentications publickey IdentitiesOnly yes IdentityFile ~/.ssh/homeserver Let me know if I can provide any log files or something like that
