Public bug reported: I use umask 066 in all profiles. Maybe this is the cause.
The console output: $ flatpak run org.kde.krita error: Error opening file /var/lib/flatpak/app/org.kde.krita/x86_64/stable/efb8b29d1255aa9bbd77212c991c0e82710b0357a5f1c167bce1fb4202ebeadf/deploy: Permission denied $ ProblemType: Bug DistroRelease: Ubuntu 18.04 Package: flatpak 1.0.7-0ubuntu0.18.04.1 ProcVersionSignature: Ubuntu 4.15.0-47.50-generic 4.15.18 Uname: Linux 4.15.0-47-generic x86_64 ApportVersion: 2.20.9-0ubuntu7.6 Architecture: amd64 CurrentDesktop: LXDE Date: Wed Apr 24 08:42:53 2019 EcryptfsInUse: Yes InstallationDate: Installed on 2018-06-11 (316 days ago) InstallationMedia: Lubuntu 18.04 LTS "Bionic Beaver" - Release amd64 (20180426) SourcePackage: flatpak UpgradeStatus: No upgrade log present (probably fresh install) ** Affects: flatpak (Ubuntu) Importance: Undecided Status: New ** Tags: amd64 apport-bug bionic ** Attachment added: "strace -o flatpack.txt flatpak run org.kde.krita" https://bugs.launchpad.net/bugs/1826109/+attachment/5258435/+files/flatpack.txt ** Summary changed: - Permission denied on runing krita (Lubuntu 18.04) + Permission denied on running krita (Lubuntu 18.04) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1826109 Title: Permission denied on running krita (Lubuntu 18.04) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/flatpak/+bug/1826109/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
