overview for DeltaWingDragon

You can use AppArmor to semi-automatically generate security profiles for each app. Once the profiles are in place, it will enforce Mandatory Access Control, securing each app that has a profile.

Here's a guide, it's designed for Ubuntu but will work with any distro.

Vimes picked himself up off the greasy cobbles and stared at the Librarian.
He was experiencing something which had come as a shock to many people,
usually in much more unpleasant circumstances such as a brawl started in the Mended Drum when the ape wanted a bit of peace and quiet to enjoy a reflective pint, which was this:
the Librarian might look like a stuffed rubber sack, but what it was stuffed with was muscle.

VSCodium can't save file if it needs root privileges (Linux Flatpak) (self.linux)

If I open a text file that needs root privileges to modify, I get this error:
Failed to save 'this_file': Insufficient permissions. Select 'Retry as Sudo' to retry as superuser.
That's fine, that's expected.

But when I click on "Retry as Sudo", I get this error:
Failed to save 'this_file': Unable to find pkexec or kdesudo.
This happens though pkexec is installed on my machine, at /usr/bin/pkexec; and I granted VSCodium access to it through Flatseal. How do I fix this?

For example, if whenever I step from a standstill, I always use my right leg. Will my legs become asymmetrical?

Look at the asterisks. It downloads far less than what it says, yet it still completes and runs fine. How‽

Firefox profile directory doesn't exist? (self.firefox)

Supposedly that is the path to my Firefox profile directory. But when I click "Open Directory", nothing happens.

When I access that file path, the directory (k45qdkms.default-release) does not exist.

Encrypted home partition doesn't decrypt on boot (self.linux)

I just installed a Debian 13 Trixie system on my laptop. I have 5 GPT partitions on 1 terabyte SSD and NO LVM!
partition layout
sda1 vfat 256M   EFI system partition
sda2 ext4 512M   boot partition
sda3 LUKS 460G   encrypted root
--   sda3_crypt  root partition, unlocks with passphrase
sda4 LUKS 465G   encrypted home
--   sda4_crypt  home partition, unlocks with passphrase
sda5 LUKS 4G     encrypted swap
--   sda5_crypt  swap partition, unlocks with keyfile
GRUB works fine, it loads the kernel, then I enter the password to decrypt my root partition. It decrypts correctly, then hangs for 1 minute 30 seconds.

After that, I get this error:
[ TIME ] Timed out waiting for device dev-mapper-sda4_crypt.device - /dev/mapper/sda4_crypt.
[DEPEND] Dependency failed for home.mount - /home/
[DEPEND] Dependency failed for local-fs.target - Local File Systems.
[DEPEND] Dependency failed for systemd-fsck@dev-mapper-sda4_crypt.service - File System Check on /dev/mapper/sda4_crypt.
[ TIME ] Timed out waiting for device dev-mapper-sda5_crypt.device - /dev/mapper/sda5_crypt.
[DEPEND] Dependency failed for dev-mapper-sda5_crypt.swap - /dev/mapper/sda5_crypt.

Not once does it ask me for the password to decrypt my home partition, it just waits until it fails.

Timeshift crashed my desktop! (self.linux)

When I use the Timeshift GUI to create a snapshot, it takes a very long time to complete. If I click Cancel, my desktop environment crashes and I get kicked to a black screen or a login prompt.

When I use Timeshift CLI, it creates the snapshot in less than a second, but the command waits for a long time afterward. However, it can be safely interrupted with control-C.

Timeshift is in BTRFS mode.
