Big Issues After Installing Kicksecure 18

1. After removing the SysMaint secure feature, I installed VeraCrypt, but I’m unable to decrypt or mount any volume; it says that the device is busy.
2. The Tor Browser is crashing frequently.

any suggestions?

After removing the SysMaint secure feature, I installed VeraCrypt, but I’m unable to decrypt or mount any volume; it says that the device is busy.

It’s hard to say what the root cause is without knowing the exact error message, but this might be a consequence of:

Set `bdev_allow_write_mounted=0` · Kicksecure/security-misc@e43d4d7

Try editing /etc/default/grub.d/40_kernel_hardening.cfg, and comment out the line GRUB_CMDLINE_LINUX="$GRUB_CMDLINE_LINUX bdev_allow_write_mounted=0". Does that fix it?

@Roxy

The Tor Browser is crashing frequently.

Are any error messages shown when this happens? If you run torbrowser in a terminal, then use it until it crashes, are any messages printed to the terminal immediately before the crash?

Try editing /etc/default/grub.d/40_kernel_hardening.cfg, and comment out the line GRUB_CMDLINE_LINUX="$GRUB_CMDLINE_LINUX bdev_allow_write_mounted=0".

Plus run:

sudo update-grub

grub bootloader Configuration Changes

Alternatively, you could perhaps more easily use Temporary Kernel Boot Parameter Change to test this without the bdev_allow_write_mounted=0 kernel parameter.

it worked after commenting the line, thanks.
