--- Comment #3 from Toni Asensi Esteve <toni.ase...@kdemail.net> --- > 2. For F3, a correct error dialog is shown. I'll attach a screenshot. Thanks, Nikita! I've tried pressing F3 on /swapfile and I see the same error message as you see, although pressing F3 on /vmlinuz.old I don't see any error dialog (just a window that is closed immediately). :-? Those are the permission of those files: $ ll /swapf* /vm* -rw------- 1 root root 545367040 abr 23 10:31 /swapfile lrwxrwxrwx 1 root root 30 jun 17 16:08 /vmlinuz -> boot/vmlinuz-4.15.0-23-generic lrwxrwxrwx 1 root root 30 jun 17 16:08 /vmlinuz.old -> boot/vmlinuz-4.15.0-22-generic $ ll /boot/vmlinuz-4.15.0-23-generic -rw------- 1 root root 8257272 may 23 19:49 /boot/vmlinuz-4.15.0-23-generic If I execute less /vmlinuz.old; less /swapfile; less /non_existant_file then I see /vmlinuz.old: Permission denied /swapfile: Permission denied /non_existant_file: No such file or directory but using F3 to see /vmlinuz.old (or /vmlinuz) I don't see any error message (at least using Kubuntu 18.04), does it happen to you, Nikita? -- You are receiving this mail because: You are watching all bug changes.
