Libreoffice freezes the computer

Briefly describe your issue below:
Hello,

When I run the following command the computer freezes.
firejail --noprofile /usr/bin/libreoffice

I want to run libreoffice outside the sandbox, just to test something.
I have a certificate that I imported according to these steps:


but I can not see it in LibreOffice. I want to check if this happens because of any restrictions imposed by firejail sandbox.

Thanks!


What version of Parrot are you running? (include version, edition, and architecture)
Parrot 4.2

What method did you use to install Parrot? (Debian Standard / Debian GTK / parrot-experimental)
Debian standard

Configured to multiboot with other systems? (yes / no)
No

If there are any similar issues or solutions, link to them below:

If there are any error messages or relevant logs, post them below:

This is wrong, to disable firejail try these:

1, firejail --noprofile libreoffice
(use the command instead of the absolute path)

2, /usr/bin/libreoffice
(When you start from executable, it simple ignore firejail)

fixed, please dist-upgrade the system!

Thank you! :beer:

On my Parrot installation, LibreOffice also freezes. I installed Parrot just yesterday and ran apt-get update and apt-get upgrade right after installation.

I am using Parrot OS (Parrot Home 4.5.1) with MATE 1.20.4 and LightDM. This is not a multi-boot installation.
I have also noticed that Pluma never launches, so I am using Geany instead as an editor.

LibreOffice freezes when I launch it from MATE’s application menu, when I run libreoffice in the MATE terminal and when I run firejail --noprofile libreoffice in the MATE terminal.

In fact, in each of these cases the entire operating system freezes within less than a second of launching LibreOffice, and I need to shut down the PC using the power button.

Thank you for bringing that to attention. I just tested the same on mine and with the same result.

My configuration is the same as yours.

I managed to get to a TTY session (CTRL+ALT+F#) and then run

sudo systemctl restart lightdm

Then I am able to use the desktop again. I am downloading the new RC, I’ll see if LO works on there.

Update: I can get Libreoffice to start without issue when I use:

/usr/bin/libreoffice

Possibly a firejail / apparmor issue again @palinuro?

Apologies for the incoming wall of text, but here is the output of Libreoffice freezing:

e]0;firejail libreoffice astarting application
LD_PRELOAD=(null)
execvp argument 0: libreoffice

I have same problem with LibreOffice, but I did find this fix, that worked for me and Pluma:
Open Mate Terminal

sudo nano /etc/firejail/pluma.profile

Uncomment (remove the # tag) :
#private-lib pluma

Save and Exit

Credit to original poster, of whom I didn’t save his name :frowning:

For what it’s worth, I have noticed that LibreOffice doesn’t freeze when I launch it from the root terminal (simply entering libreoffice) instead of from the normal MATE terminal or the menu.

Also on new KDE install, no problems with libre, only on Mate.
