[Linux] Default app store behind on vesions?

I use Pop!_OS, and it looks like the latest version they have is 7.3.7.2, but online I see the latest version is something 26.2.3. The weird thing is that when I open up the app store, there will occasionally be updates for the LibreOffice suite, so it’s not like my app store just stopped getting new versions. What’s going on?
Is this also a problem on Ubuntu?
Sorry if I chose the wrong tag. I didn’t see one that looked like it fit my question.

There is no need to use whatever »»appstore«« they provide

  • download the …deb packages for your platform from official Downloadpage plus optional the Language-packages plus optional the Help-packages for your Language.

  • extract the downloads

  • cd into subfolder …/DEBS/ and install via sudo dpkg -i *.deb (repeat the last for Language- and Help-Packages)

(my name)@pop-os:~/Programs/LibreOffice/LibreOffice_26.2.3_Linux_x86-64_deb$ sudo dpkg -i *.deb

dpkg: error: cannot access archive '*.deb': No such file or directory

Ok, I tried it again, and it seemed like something happened, but when I tried entering libreoffice --version again, I got LibreOffice 7.3.7.2 30(Build:2).

wget https://download.documentfoundation.org/libreoffice/stable/26.2.3/deb/x86_64/LibreOffice_26.2.3_Linux_x86-64_deb.tar.gz

tar -zxf LibreOffice_26.2.3_Linux_x86-64_deb.tar.gz

cd /LibreOffice_26.2.3.2_Linux_x86-64_deb/DEBS


sudo dpkg -i *.deb

you cannot run two instances of soffice at the same time … until you run one of them with its own user-config, eg:

/opt/libreoffice26.2/program/soffice -env:UserInstallation=file:///home/ »your_name« /tdf_office

Will this make it so that the latest version boots up when I select a LibreOffice app?

without the -env:… switch, any later run-command will fallback to the current running instance of Libreoffice

A bit of background:
Linux usually has a quite efficient system to handle updates automatically via your distribution. On debian-based distributions this uses mostly apt and .deb-packages, but .rpm is is common on distributions based on RedHat.
.
Advantage of above: Common libraries are shared and updates in this libraries can come directly via the distribution, even if there is no update for your app.
.
Disadvantage of above: Maintaining compatibility of all components can be complicated over time. So distributions decide to

  • only maintain versions for a limited time
  • don’t offer “big” updates (like raising LibreOffice from 6.x to 7.x)
  • limit updates to the core for their LTS-versions.

This is also true for Ubuntu, but I read System76 maintains their own repository for PopOS. So coverage of versions may be different.
.
For all this distributions you are expected to do a dist-upgrade from time to time. (Another option are “rolling” distributions. They update everyting anytine, so are more likely to produce unexpected problems… - according to Murphy’s law at the most uncomfortable time…)
.
To avoid outdated versions and frequent dist-upgrades Appimage, Snap and Flatpack were invented. This bundles “everything needed” with the app. So packages are much bigger.
I read PopOS uses Flatpack.

PS: As 7.6 was followed by 24.x your version is not so much behind as numbers may suggest.
