Rosegarden 21.12 Crashes

[OmegAudio]

I went back to the original script: ~$ sudo chown -R $USER:$USER ~ (I replaced user with my name)
The script takes only a second or two to run. And my RoseGarden test files do not change owner or group.

I ran the code: sudo chown -R $user:$user ~ (user is replacement for actual name)

If you mean you ran
sudo chown -R $jack:$jack ~
if your username is jack, that doesn't work. USER is a specific environment variable, $USER is its value. When you run the command with your username jack, you should replace $USER with jack.

sudo chown -R jack:jack ~

but you could just run it with $USER, provided you're not logged in as root, or use a root shell (in the latter case the terminal prompt has changed from ~$ to #, don't know about the former). You can check with
echo $USER
ran verbatim.

This is the exact script I ran:
sudo chown -R chris:chris ~

This is the exact script I ran:
sudo chown -R chris:chris ~

What does
echo $USER
return?

[folderol]

I wonder if you've somehow managed to get ownership but not write permission.

[OmegAudio]

This is the exact script I ran:
sudo chown -R chris:chris ~

What does
echo $USER
return?

When I open terminal and run:
echo user
It returns "user" for a value.
There is only one profile and one user, myself, on the computer. And when it boots it is set to open to the desktop.

$USER, not user...

Anyway, I'm out of ideas. Hope you can fix it someday.

when I ran echo $USER it returned nothing.
When I ran echo user it returned user

I know I should not be using terminal and sudo rosegarden.
But that makes it work.

I went back and tried again: echo $USER
Instead of echo $user
and it returns: chris (which is my user and group)

You could try
sudo chown -R -v $USER:$USER ~
The -v option gives feedback for every file it processes, even if ownership doesn't change.

or
sudo chown -v $USER:$USER testfile
on that root owned testfile of yours. Could give some valuable info.

Greetings, I ran this: sudo chown -R -v $USER:$USER ~
And every file in the list has retained as chris:chris
It is a very long list and I am not sure I can see everytyhing.
Because when I get to the top I do not see the command I entered.

[OmegAudio]

I try to open Rosegarden then open one of the .rg files and again Rosegarden crashes.
If I open terminal and run: sudo rosegarden
I can then open a project file and edit and save without crashing.

Running Rosegarden with sudo seems to be a work around. I have used Rosegarden for years. And always was able to run the application from the Show Applications and the Rosegarden Icon. And open and edit existing files. Until recently when I reinstalled Ubuntu 22.04

Maybe starting Rosegarden with strace gives some hints:

Code: Select all

strace -eopen rosegarden

Then open a rg file.

Hello bluebell
I tried using your command to see what it would record.
Here is the command I used:
strace -eopen rosegarden

Then Rosegarden opened. And I then opened my test file and it crashed.

Unfortunately that doesn't give any hints for the crash.

@OmegAudio
You are using a quite old version. Next week version 23.12 will be published. In the meantime you can download from my website the latest release compiled yesterday for Debian 12 (should also work in Ubuntu): "www.stockinger.org", then klick on the "Musik"-Tab.

Did you delete the existing config file in your home directory and restart Rosegarden?

Start Rosegarden from a terminal and read the output. Maybe some messages will help.

Good Morning Barbarosa
The old version is what is provided by the Ubuntu application repository.
I did uninstall and reinstall with no change.

Delete the existing config file? I have not yet learned how to do that. That is on my list to learn.

When I start from a terminal it does provide a long list of actions.
I will capture that and provide ASAP.

Greetings Babarosa
Here is the logging from Terminal when I opened Rosegarden.
Then closed Rosegarden
I only use Rosegarden for Midi. And it works wonderfully when I open from Terminal with sudo, as seen below.

I appreciate your input.
