Can i install and run programs from inside chroot directory?

[Chrisdb]

Is '/path/to/old/firefox' this directory ~/.mozilla? Because if i run:

Code: Select all

firejail --private=~/Firejail_home/Firefox_old ~/.mozilla/ -no-remote

i get this error:

Code: Select all

Error: invalid command name

replace:

Code: Select all

-no-remote

with:

Code: Select all

--no-remote

Tried '--no-remore' but got the same error.

But i need to use this command? Isn't this way more simple:

I created three folders:

Code: Select all

~/Firejail_home/firefox1
~/Firejail_home/firefox2
~/Firejail_home/firefox3

And if i want to run any of the three firefox profiles i use these commands:

Code: Select all

firejail --private=~/Firejail_home/firefox1 firefox
firejail --private=~/Firejail_home/firefox2 firefox
firejail --private=~/Firejail_home/firefox3 firefox

[Chrisdb]

The 'no-remote' option is used to avoid connecting to a running instance
Something like:

Code: Select all

firejail --private=~/Firefox_old firefox --no-remote

should work..

[emil_21]

Yes, this worked.
I tested firefjail --private option with kodi 17, which is in the debian repository, and it worked too.

It will be great if i can do that with Kodi using firejail. But what is the best way to install kodi 17 and kodi 18? I can't use .deb files and install them both system wide. Kodi is not available as appimage, and as flatpak only kodi 18 is available.

Here is a potential solution: https://bedrocklinux.org/

I've never used it, but I believe that it can provide you with the capability that you are seeking. However, the Nix package manager I told you about earlier seems like a much simpler solution.

Indeed, it looks really interesting.

@pcalvert, any personal experience ?

[emil_21]

@pcalvert, i installed Nix package manager but it doesn't seem to work. If i type

Code: Select all

sudo nix-env --install firefox 

i get

Code: Select all

sudo: nix-env: command not found

This is from the end of the install script:

Code: Select all

Installation finished!  To ensure that the necessary environment
variables are set, please add the line

  . $p

to your shell profile (e.g. ~/.profile).
EOF
else
    cat >&2 <<EOF

Installation finished!  To ensure that the necessary environment
variables are set, either log in again, or type

  . $p

in your shell.
EOF
fi

After installing nix, did you do what the installer script told you to do?

I just found something that may be helpful: Nix tutorial

It appears to be rather thorough. There is also the manual: https://nixos.org/nix/manual/

I got this at the end of the installation:

Code: Select all

Installation finished!  To ensure that the necessary environment
variables are set, either log in again, or type

  . /home/user/.nix-profile/etc/profile.d/nix.sh

I execute the command but still get 'command not found' when i try to execute nix-env. This is my .profile file:

Code: Select all

# ~/.profile: executed by the command interpreter for login shells.
# This file is not read by bash(1), if ~/.bash_profile or ~/.bash_login
# exists.
# see /usr/share/doc/bash/examples/startup-files for examples.
# the files are located in the bash-doc package.

# the default umask is set in /etc/profile; for setting the umask
# for ssh logins, install and configure the libpam-umask package.
#umask 022

# if running bash
if [ -n "$BASH_VERSION" ]; then
    # include .bashrc if it exists
    if [ -f "$HOME/.bashrc" ]; then
	. "$HOME/.bashrc"
    fi
fi

# set PATH so it includes user's private bin if it exists
if [ -d "$HOME/bin" ] ; then
    PATH="$HOME/bin:$PATH"
fi

# set PATH so it includes user's private bin if it exists
if [ -d "$HOME/.local/bin" ] ; then
    PATH="$HOME/.local/bin:$PATH"
fi
if [ -e /home/user/.nix-profile/etc/profile.d/nix.sh ]; then . /home/user/.nix-profile/etc/profile.d/nix.sh; fi # added by Nix installer

Is the search function broken in these forums? I posted a way to install my buster backport of Kodi 18.5 only a day or so ago!

[pcalvert]

I execute the command but still get 'command not found' when i try to execute nix-env.

Did you try logging out after you installed it?

If that doesn't help, what is the output of these commands?:

Code: Select all

ls -al ~/.nix-profile
ls -al /nix

[emil_21]

This is the output:

Code: Select all

lrwxrwxrwx 1 user user 42 фев 13 10:39 /home/user/.nix-profile -> /nix/var/nix/profiles/per-user/user/profile

Code: Select all

drwxr-xr-x  4 user  root 4096 фев 13 10:39 .
drwxr-xr-x 19 root root 4096 фев 13 10:39 ..
drwxr-xr-x 35 user  user  4096 фев 13 10:39 store
drwxr-xr-x  4 user  user  4096 фев 13 10:39 var

I'm not sure what the problem is, but it's possible that Nix doesn't properly install itself on Debian. Or maybe the installation instructions are incomplete.

I found a possible clue, though:

At this stage, nix is properly installed on your system, but some extra configuration is required, especially to activate the “profiles” feature.

I found that here: Working with profiles : create several user environments
