Cant start gaphor on Ubuntu 22 VM

[DirtyStreetCoder]

Describe the bug

Hi, I was interested in your project and set up a clean new Ubuntu 22.04.4 VM.

To Reproduce

After installing python 3.10.12 i tried your install documentation

https://docs.gaphor.org/en/latest/linux.html
Install Flatpak

Install flatpak-builder

sudo apt-get install flatpak-builder
Install the GNOME SDK

flatpak install flathub org.gnome.Sdk 43
Clone the Flathub repository and install the necessary SDK:

git clone https://github.com/flathub/org.gaphor.Gaphor.git
cd org.gaphor.Gaphor
make setup
Build Gaphor Flatpak

make
Install the Flatpak

make install

When i run
gaphor

I get a bunch of errors

Settings schema not found and settings won't be saved, run poe install-schemas`

I tried some approaches from you latest video with the same result...
https://www.youtube.com/watch?v=9BYgI1nJCBA

Expected behavior

gaphor GUI opens

Screenshots

n.a.

OS

• Linux (Ubuntu 22.04.4 VM on VirtualBox 7.0.12)
• macOS
• Windows

Version

Version of Gaphor: latest (i assume, don't know how to verify)

Additional information

A video from scratch would be nice. I may be able to do that once it works.

Hi @DirtyStreetCoder, Gaphor depends on libadwaita 1.4.0 or newer. If you want to run it in a VM or on any Linux outside of Flatpak, you'll need to have a very new distribution version. For example, Ubuntu 2023.10, openSUSE Tumbleweed, or Fedora 39.

I also checked and this is mentioned in the docs rights under this section: https://docs.gaphor.org/en/latest/linux.html#a-local-environment. It does say latest Ubuntu LTS or newer, in the case you need "or newer" because the next LTS will be released next month. 😄

If you think the docs could be more clear, maybe we should just say the latest release of Ubuntu instead of latest LTS, we would be glad for a PR. Thanks!

Hi @danyeaw , thanks for the quick reply. I did indeed not see that hint :-)

Ok, so i tried it again with ubuntu 23.10.1

Did all the flatpak steps...
.
.
.
cd org.gaphor.Gaphor
make setup
make
make install

but the when i enter "gaphor" I get
"gaphor: command not found"

Running the make... steps again tells me
Error: org.gaphor.Gaphor already installed error: Failed to install bundle org.gaphor.Gaphor: This version of org.gaphor.Gaphor is already installed make: *** [Makefile:57: install] Error 1

What am i doing wrong this time?

Sorry to bother you again.

Hi @DirtyStreetCoder, it sounds like you are successfully building the flatpak, which is great! To run a flatpak, you'll need to give the full name like flatpak run org.gaphor.Gaphor.
