Notes-up has problems starting since September 2023. It is a great notes taking app and I would love to use it again.
There is an issue on the github page of the project but the maintainers says that manjaro host the app itself.
Can you please fix the problem. There are different manjaro users with this problem (see issue) and no user of a different distro has posted about this problem.
It looks more like, as it is with most packages, that this package comes directly from Arch (not maintained by Manjaro separately).
And in Arch, it is flagged as out of date since September 15th 2024
Notes-up starts fine here; tested on KDE Plasma (Stable).
Your problem is likely specific to your environment.
To verify this, please create a new User account and test launching the app there. If it launches as expected in the new account, then there is no issue with Notes-up itself.
You might also consider replacing Notes-Up perhaps with Obsidian, for example:
I am on unstable branch.
sudo pacman -S obsidian
I use it myself; it’s quite impressive.
Cheers.
There is also this one:
https://rednotebook.app/index.html
Available in extra.
Been years since I used it (back in my Mint days), but I remember it was pretty good.
I don’t use such a program these days, but instead I organize my thoughts in text files. Easy to search using grep.
As the OP seems to want us all to guess what DE they are using (it would be helpful if they would add some information to their profile via Forum Profile Preferences), I’ll throw in the lightweight QT-based FeatherNotes as a recommendation. It is in the Manjaro Extra repo.
I installed FeatherNotes back in May after the Plasma ToDoList widget was not ported from Plasma 5 to Plasma 6. It has all the features I want, including auto-saving of notes. It also sits in the system tray. I added it to my autostart so that it is always available if I need to jot something down.
I just found Inkdrop, which is a paid option; however, if you like the general layout and don’t care much for the online sync feature and plugins, you might be content instead with Notable (which I also use).
pamac build notable-bin
As the OP after 7 days has seemingly not bothered to respond to any posts in this thread, this will also be my final attempt to encourage a response.
As is the Kde marknotes, which successfully picked up all of the notes and folders that I had previously made in obsidian.
notes-up is inherited from Arch and not maintained by Manjaro
Arch Linux - notes-up 2.0.6-2
Flagged out-of-date on Sept. 15, 2024
won't start · Issue #399 · Philip-Scott/Notes-up · GitHub
So I’m not actually the one hosting the one on the Manjaro repo. But there is a Flatpak hosted by the community which may work better: Install Notes-Up on Linux | Flathub
My guess is that Manjaro has updated dependencies that do not work with the current version of Notes-up. (Probably a new GKT version)
I’m not going to be able to debug & fix this super quickly, but do you mind trying out the Flatpak to see if it at least makes the app run?
This highlights the inherent simplicity of working with markdown (text) files, generally, as one can easily move from one application to another with minimal fuss. Markdown in its purest form will always survive the transition.
That said, and as much as I appreciate Obsidian (which I use frequently), with any application designed to extend markdown capabilities (via plugins, for example) there is always a risk of features not surviving that transition; of not being understood by another application.
Often this isn’t a deal breaker, as the feature may simply fall back to more basic markdown rendering; but, in some cases it might not; perhaps forcing a need to manually re-edit documents concerned.
Sorry, added. Also there were more people for whom it stopped working. So I assumed it is not DE specific.
Thanks. I did not know that. Though I thought that everything that is in the manjaro repo should work.
Yeah. That is one thing I was specifically looking for.
Does it work without root? Its weird that it does work with root on my system. That is why I wanted to find a solution for notes-up rather than switching to a new app.
Appreciate all the suggestions and will have to seen when I have time to properly check them.
I am very sorry there is such a thing as real life. I’m really happy that you all are trying to help me though.
It works without root. It must be a problem with the config files of notes-up in your case.
If you do not have time for debugging outdated package on Manjaro, I suggest using the Flatpak version
If you’ve been starting it with sudo this may have changed the permissions/ownership of the relevant configuration file(s). This might be why it won’t start as a normal user?
It is never a good idea to start graphical applications using sudo for this reason.
Everything we do is a part of real life;
including seeking help in a forum. 
I suppose the OP could do worse than this:
find /home/$USER -user root
… and post those results here. This will help greatly if what I suggested in my previous post is (part of?) the issue as it should be an easy fix.
ATM I don’t want to use flatpak on this machine.
I only tried that after it was already broken and to test whether it works for me like somebody else suggested.
Nothing related to this app. Where is the config file?
Will have to do some real life things outside this forum in the coming days.
Not exactly sure what it’ll be called as I don’t have that program; should be in ~/.config/ though.
I made a test file — the bottom one — and gave it root ownership, then ran the command:
find /home/$USER -user root
/home/brian/usb1.vmdk
/home/brian/ToE_ROM.bin
/home/brian/.config/testroot.conf
Ignore the top two.
outdated packages are likely not to work on a rolling release distribution
That was maintainer’s suggestion to possibly get a working package as they are “not going to be able to debug & fix this super quickly”
Package has still not been updated on Arch repositories
The command worked for me but did not find anything related to notes-up.
