Slackware 15 & Flatpak

I have Slackware 15 installed and fully updated.

I installed flatpak from Ponce's repo with no issues.

However when I stall flatpak apps I notice two things happen.

1 - I am getting the following warning:

Warning: Failed to get revokefs-fuse socket from system-helper: User flatpak does not exist in password file entry

2 - After the app is installed the apps don't launch. They flash on the screen quickly and don't open. When starting them from the command line I am getting an error. For instance I installed makemkv and am getting the following error when trying to launch it from the command line:

$ flatpak run com.makemkv.MakeMKV.desktop
error: app/com.makemkv.MakeMKV.desktop/x86_64/master not installed

Am I missing a part of the setup for flatpak?

Did you try to run it as a normal user (not root) or restart the machine???

Yes, I've ran it as root and as a normal user and have restarted my PC after installing it. They still won't open.

Which iso did you download slackware live or stable ?
Did you read the slackbuild info ?
run this on a terminal

flatpak --user remote-add --if-not-exists flathub \
     https://dl.flathub.org/repo/flathub.flatpakrepo

and check again if you have the same error
look here if you forgot any dependencies

https://slackbuilds.org/repository/14.2/desktop/flatpak
and here
https://github.com/afhpayne/flatpak_slackbuild

I have stable installed, now that it's released. All dependencies are installed and I'm still getting the same error. It's quite perplexing.

Your user is on wheel group?

It wasn't originally as I don't usually enable sudo, but I just did now by doing the following:

-

visudo

then uncomment the following line:

## Uncomment to allow members of group wheel to execute any command
 %wheel ALL=(ALL:ALL) ALL

-

root@hitch1:/home/justin# usermod -a -G wheel justin

I then rebooted and am still getting the same error.

I guess flat pack will need lots of setting up.

I have flatpak and slackware 15, and flatpak is working for me.

1. The warning message you are seeing didn't affect my flatpaks when I would install them, but I was able to fix it by looking at this issue https://github.com/flatpak/flatpak/issues/2959. There is one post that has a link to the Fedora flatpak spec file, and in there there are the commands to create the flatpak user and group, which is what the warning is complaining about. For convenience, I'll just paste the commands here.
getent group flatpak >/dev/null || groupadd -r flatpak
getent passwd flatpak >/dev/null || \
useradd -r -g flatpak -d / -s /sbin/nologin \
-c "User for flatpak system helper" flatpak
paste the first line into the terminal then paste the last 3 all together into the terminal. This worked for me, but don't know if it would work for you.

2. Have you tried installing multiple flatpak apps, or just that one? If it is just that one app, it could be an issue with the app. The flatpaks I have on my computer are all working and I haven't had any issues like that.

With that in mind, SBo admins have recently allocated 372 for uid & gid - see:

https://slackbuilds.org/uid_gid.txt

The maintainer may just be waiting for the next update to include the user/group creation.

As an aside, flatpak works in Slint64-14.2 but with 212:999. I will change that for consistency with SBo in Slint64-15.0...

1. I did this and am still having the same problem.

2. I also installed bitwarden and that also doesn't open.

make sure the user and group were actually created.
# getent passwd flatpak
# getent group flatpak

run those two commands to see if you get an output that indicates whether the flatpak user and group is present on the system. Other than that, I don't think I'll be much help as I haven't had issues like this with flatpak.

$ getent passwd flatpak
flatpak:x:329:999:User for flatpak system helper:/:/sbin/nologin

$ getent group flatpak
flatpak:x:999:

It looks like they are there. Is this how they are supposed to look?

yes, that shows that the flatpak user and group are on the system. This should only get rid of that warning, not solve the flatpak issue.

are you trying to install this app. https://flathub.org/apps/details/com.makemkv.MakeMKV
the command to run it should be

flatpak run com.makemkv.MakeMKV

not

flatpak run com.makemkv.MakeMKV.desktop
