Original GitHub issue: https://github.com/netblue30/firejail/issues/4104

Bug and expected behavior
Once you run the command: sudo firecfg
it results in a not usable office suit with loading time and than failing to start.

im only getting this kind of errors with Intel © Core™ i7 and not with AMD.

tags: libreoffice firejail break fail to start

workaround / "fix"
download the libreoffice appimage https://www.libreoffice.org/download/appimage/
move it into /opt/LibreOffice-still.full-x86_64.AppImage
sudo rm /usr/local/bin/libreoffice && sudo nano /usr/local/bin/libreoffice
put the following line in there:

firejail --profile=/etc/firejail/libreoffice.profile --appimage /opt/LibreOffice-still.full-x86_64.AppImage $1

sudo chmod +x /usr/local/bin/libreoffice

enjoy working with firejailed libreoffice again

Environment
Linux Mint 20.1, tested this issue on two machines
firejail version 0.9.62

Compile time support:
- AppArmor support is enabled
- AppImage support is enabled
- chroot support is enabled
- file and directory whitelisting support is enabled
- file transfer support is enabled
- firetunnel support is enabled
- networking support is enabled
- overlayfs support is enabled
- private-home support is enabled
- seccomp-bpf support is enabled
- user namespace support is enabled
- X11 sandboxing support is enabled

firejail version 0.9.62

Please update this 0.9.62 version as soon as possible. Besides being outdated it is vulnerable to CVE-2021-26910, which is fixed in 0.9.64.4. You can install/update firejail from this PPA, which happens to be maintained by one of our collaborators.

It could be that you'll encounter the reported issue on the latest stable release too, but at least we then have a sound 'base' to start looking at it in detail.

Can you post /usr/bin/libreoffice.

OT: %U is .desktop syntax. If you use it in your shell, you ask LO to open the document with the filename %U in the current working directory.
