Critical requirement missing: qtpaths Install it and try again

I opened the Discover software and it said there are updates for certain packages. I wanted to update Kompare. But after it ran. I get this in the terminal.

That installer isn’t complaining about Kompare itself — it’s complaining that your system is missing the Qt6 tool qtpaths6 (it uses it to find KDE/Plasma paths for the Dolphin service menu). On Debian 13, qtpaths6 is not in a package called qtpaths; it comes from qt6-base-dev-tools.

Run:

sudo apt update

Quick sanity check:

command -v qtpaths6

Then re-run the installer from that directory (or just run it explicitly):

bash ./install.sh --install

Why you saw --locate-dirs: not found

Those lines happen because the script tries to run something like:

$QT_PATHS_BIN --locate-dirs

…but since qtpaths6 wasn’t installed, that variable ends up empty, so the shell tries to execute --locate-dirs as if it were a command.

Once qt6-base-dev-tools is installed, that goes away.

If anything still fails after that, paste the output of:

qtpaths6 --locate-dirs

I don't know it if worked, I see 3 qstorage destoyed errors at the bottom. adam@laptop:~$ command -v qtpaths6 qtpaths6 --help | head /usr/bin/qtpaths6 Usage: qtpaths6 [options] [name] [properties] Command line client to QStandardPaths and QLibraryInfo Options: -h, --help Displays help on commandline options. --help-all Displays help, including generic Qt options. -v, --version Displays version information. --types Available location types. adam@laptop:~$ kompare -v kompare 4.2.25042 QThreadStorage: Thread 0x556a4dd574c0 exited after QThreadStorage 9 destroyed QThreadStorage: Thread 0x556a4dd574c0 exited after QThreadStorage 1 destroyed QThreadStorage: Thread 0x556a4dd574c0 exited after QThreadStorage 0 destroyed adam@laptop:~$

Yep — it worked.

• command -v qtpaths6 returning /usr/bin/qtpaths6 means the missing requirement is now installed.
• kompare -v printed the version, so Kompare itself is launching fine.

About those “QThreadStorage … destroyed” lines

Those messages are not fatal errors. They’re Qt “warning-ish” shutdown noise that some KDE/Qt apps print when they exit (especially when run from a terminal). If Kompare opens and works normally in the GUI, you can safely ignore them.

If you just don’t want to see them in terminal output, you can suppress stderr:

kompare -v 2>/dev/null

Verify the Dolphin right-click service menu actually installed

On Plasma 6, Dolphin service menus typically land here:

ls -l ~/.local/share/kio/servicemenus | grep -i kompare

If you see a .desktop file there, it’s installed. Then restart Dolphin so it reloads service menus:

kquitapp6 dolphin 2>/dev/null; dolphin &

(Or just close/reopen Dolphin.)

If you don’t see anything in that folder, re-run the installer script now that qtpaths6 exists:

cd ~/.local/share/servicemenu-download/compare-with-kompare-1.2.0.bundle.tgz-dir/compare_with_kompare

If it still doesn’t show up in Dolphin after that, paste the output of the installer run (the last ~30 lines) and I’ll tell you exactly where it placed the files or what it’s failing on.

You said:
ok, well, i can launch Kompare from the application launcher menu. so I guess its ok, but just showing you want I got below adam@laptop:~$ kompare -v 2>/dev/null kompare 4.2.25042 adam@laptop:~$ ls -l ~/.local/share/kio/servicemenus | grep -i kompare adam@laptop:~$ kquitapp6 dolphin 2>/dev/null; dolphin & [1] 6895 adam@laptop:~$ kf.kio.core.connection: Socket not connected QLocalSocket::PeerClosedError kf.kio.core: An error occurred during write.

Kompare itself is fine (it prints a version and launches). What didn’t happen yet is the Dolphin right-click service menu install.

1) Those Dolphin / KIO messages are basically harmless

When you do kquitapp6 dolphin; dolphin &, sometimes the old Dolphin/KIO worker dies mid-IPC and you see:

• Socket not connected / PeerClosedError
• The worker terminates now
• QThreadStorage ... destroyed

That’s shutdown noise, not “your system is broken”.

If Dolphin is acting weird after that, just fully kill it and relaunch clean:

killall dolphin 2>/dev/null

2) Why you don’t see the service menu

This line:

ls -l ~/.local/share/kio/servicemenus | grep -i kompare

returned nothing, so the service menu file wasn’t installed (yet). Earlier, the installer aborted because qtpaths6 was missing — so it never copied the .desktop service menu into place.

3) Re-run the service menu installer now that qtpaths6 exists

Run this:

cd ~/.local/share/servicemenu-download/compare-with-kompare-1.2.0.bundle.tgz-dir/compare_with_kompare

Then check again:

ls -l ~/.local/share/kio/servicemenus | grep -i kompare

Restart Dolphin cleanly:

killall dolphin 2>/dev/null

4) If it still doesn’t show up, find where it installed (or why it didn’t)

Check the installer log it mentioned:

tail -n 80 install.log

And search for any installed service menu file:

find ~/.local/share -type f \( -iname '*kompare*' -o -iname '*compare*kompare*' \) 2>/dev/null

Paste the last ~80 lines of install.log if it still refuses — that will usually show the exact destination path it chose and what it did next.

Perfect — that’s exactly what you wanted:

• Service menu installed ✅ (compare_with_kompare.desktop in ~/.local/share/kio/servicemenus)
• Dolphin restarted ✅

What do you want to tackle next?
