Qownnotes: Not launching on ubuntu armhf - Critical error

[badrow]

Hi, i'm getting this error while trying to launch it on an ubuntu armhf machine. The app does not start.

Critical: SingleApplication: Unable to attach to shared memory block. ((null):0, (null))
Critical: "QSharedMemoryPrivate::initKey: unable to set key on lock" ((null):0, (null))

Any idea please ?

[pbek]

Interesting, no shared memory? Try to run QOwnNotes --allow-multiple-instances.

[pbek]

If that works you can turn off single application in the General settings. And can you then please post the dump from the Debug settings?

[badrow]

It works ! Thank you, I'll post the dump.

And can you then please post the dump from the Debug settings?

You posted log output. ;)

[déc 14 15:31:43] [warning]: QXcbShmImage: shmget() failed (38) for size 1702624 (1231x691)

haven't seen that before...

[pbek]

What device are you using? Doesn't it have shared memory?

[badrow]

I use a really strange configuration so it's a miracle the app is launching (linux ubuntu 16.04 container used via VNC, on android tablet with armhf cpu)

There is no dump option in the debug settings...

[badrow]

It's a chroot container.

can you please post the dump from the Debug settings? Menu: Note / Settings / Debug

There is no dump option in the debug settings...

there must be a huge block of text there :)

interesting setup indeed :)

I found the huge block of text, i'm just changing private information and I'll send it

Yes the setup is totally weird but excellent, I can have my linux desktop everywhere like that.

[pbek]

Thank you.
Usually shared memory should not be a problem on armhf. I wonder does top show any shared memory for you?

[itay-grudev]

@adamsson6 I am the author of the SingleApplication library. Can you provide me the output of uname -a and lscpu. Thank you.

[pbek]

18.12.4

• if single application mode is enabled the app will now attempt to check if
  the mode is supported on your system and turn it off if it isn't supported

[pbek]

@adamsson6 there now is a new release, could you please test it and report if it works for you by turning single application mode on again and restarting QOwnNotes? The setting should then automatically be turned off again. I couldn't test it myself, I have no system where it fails. :smile:

[badrow]

Hi everybody sorry for the delay, nice to meet the developers of awesome pen-source aaps i'm using eveyday.
I tried thecnew version and it's working ! I think i'm the only one guy having a system where it fails lol.

I will answer to the other questions soon sorry.

Kernel 3.4 on armv7l. I'll try to reproduce it when I have time.

@adamsson6 Thanks a lot, mate.

Typically, it's an andorid device with a linux desktop installed with linuxdeploy

Thank you for developping cool stuff.

were you already able to test the new release by chance?

[pbek]

any news @adamsson6?

[badrow]

It's working ! The new version works on ubuntu and debian ! Thank you !

[pbek]

Great, thank you for testing! Did you turn single application mode on again before you started the new release? You could simply also start QOwnNotes in a new session with QOwnNotes --session test.

[badrow]

I didn't changed anything so... I guess I didn't turned it on. I will try, sorry i'm late.
I also have another question : Is it possible to add a function to disable the web socket listening on port 22222 for security reasons ? May be I should open a new issue for that ? Thank you.

[pbek]

May be I should open a new issue for that ?

yes, please
