Your home interface is connected. Do you have a non-conventional home directory, or is it the usual /home/USER? The Apparmor log indicates the latter, but I want to confirm it. In /var/lib/snapd/apparmor/profiles/snap.chromium.chromium, do you have such a section: ---> # Allow read/write access to all files in @{HOME}, except snap application # data in @{HOME}/snap and toplevel hidden directories in @{HOME}. owner @{HOME}/[^s.]** rwklix, owner @{HOME}/s[^n]** rwklix, <--- Please also attach dpkg -l|grep xdg-desktop-portal systemctl list-units --user --type=service --state=running | grep xdg-desk ** Changed in: chromium-browser (Ubuntu) Status: New => Incomplete ** No longer affects: ubuntu-personal-security (Ubuntu) ** No longer affects: ubuntu-core-security (Ubuntu) ** Also affects: snapd (Ubuntu) Importance: Undecided Status: New ** Changed in: snapd (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to chromium-browser in Ubuntu. https://bugs.launchpad.net/bugs/2085375 Title: KUbuntu 24.04 can not acceass local files from Chromium and Brave Status in chromium-browser package in Ubuntu: Incomplete Status in snapd package in Ubuntu: Incomplete Bug description: KUbuntu 24.04 can not acceass local files from Chromium and Brave. *How to reproduce* 1.
