I'm not feeling well after the update.

This time it is UBUNTU of MINIPC of Intel chipset.

The server crashes immediately after starting and does not accept operations. . .

I canceled the auto start and did various checks, but nothing works. . .

I will send you the log.

Err:Connection to INDI host at localhost on port 7,624 lost. Server disconnected: -1

what i did
・Reinstall the server driver
・Remove system apps that interfere with serial operation
sudo apt remove modemmanager
sudo udevadm control --reload
sudo apt remove brltty
sudo apt -o Dpkg::Options::="--force-overwrite" -f install

It is very worrisome that a comma appears in the port number display after updating.

If the server starts as shown in this display, it will start using port 7 and 624 → stop because it cannot communicate with port 7624.

Hm that comma seems to be locale specific. Most of the time it can cause problem when decimal separator is comma instead of dot. You may try set run "export LANG=C" and then "kstars" command. This should set locale to default C and remove comma from log. If the problem with locale this should solve it.

thank you.

I tried it immediately.

The result did not change.

It will look like the screenshot and the server will stop.

I can't use INDI after updating. . .

sudo localectl set-locale LANG=C.UTF-8 LANGUAGE=C
i also tried this.
Even if you change Kstars to English notation, it will not change.

It looks like the 7624 port is not being used.

When I start it from the command line, the server doesn't find the driver.

I want to know the location of the server preference file. . . .

QXcbConnection: XCB error: 3 (BadWindow), sequence: 8334, resource id: 17169983, major code: 40 (TranslateCoords), minor code: 0

Looking at the logs it seems to always stop with a QT error.

I verified it further.

Serial communication → OK

Connect with Indigo → OK

Trouble is only in the INDI server after the current update.

Your log shows a spelling error: "indi_sinulator_ccd" should be "indi_simulator_ccd"

The syntax for the indiserver command is not correct. It should be something like this: "indiserver -v -p 7624 indi_simulator_ccd"

Thank you for contacting us.

I tried connecting in terminal.
It still won't connect.

Same result if I change the server start method like Ekos, INDIWeb Manager, INDI Starter.

If you delete everything and install it again, INDIServer cannot be installed. . .

Are Indi and your operating system both 64-bit?
