MicroOS - 5 questions

Hello,

is anyone using MicroOS?
I am now about 1 year with openSUSE and get along very well with Leap 15.3. On another laptop I had Leap 15.4 installed and later on free partitions MicroOS to test. I like MicroOS very much, but have some questions to which I have not found answers:

  1. GRUB2 does not give a boot option for Leap 15.4, which is also installed. Does MicroOS only accept itself?
  2. how to set the GRUB_TIMEOUT? For Leap 15 I know how to do that, but here?
  3. printer installation: it is a multifunction device from Brother that is installed using an executable script. This is followed by questions that I have to answer. On Leap 15 I have to do sudo zypper ve afterwards because of 32 bit applications. How do I install a printer on MicroOS?
  4. how can I edit the fstab on a read-only system like MicroOS?
  5. during installation I specify the WLAN connection and it is created as wlp3s0b1 without errors. But later in the running system no WLAN connection is established. I use WLAN now with the help of my smartphone, but this cannot remain a permanent solution. What can I do?

I would be very happy about any help.

For 1 (BTW it is bast to have one problem per thread)

Is the boot the same ie both legacy or EFI all OS? must use the same method

Hi
For grub, modify /etc/default/grub as required, then transational-update grub.cfg and reboot. You should be able to use transactional-update run vi /etc/fstab and edit as required and again since a new snapshot reboot. I use ignition to configure some stuff, but using in containers, not as a desktop.

Hello gogalthorp and malcolmlewis,

thank you for your answers.
Yes, the boot process is the same.
I was able to set GRUB_TIMEOUT and it was applied. I then installed os-prober and after reboot did sudo transactional-update grub.cfg. But leap 15.4 remains missing.
I can edit fstab now too.
Now to the printer. With Leap 15.3 I enter:
sudo ~/./linux-brprinter-installer-2.2.3-1
then the installation starts with questions and answers. Of course this does not work with MicroOS, but with
sudo tukit --continue execute /bin/sh
it does not work. It follows the message: No such file or directory
What am I doing wrong?

Hi
Use the run command like editing fstab for the printer script (will likley need full path to it’s location.

If you run the os-prober command by itself does it see Leap 15.4?

Hello malcolmlewis,

  1. When I start os-prober, I get the message:
/dev/sda2:openSUSE Leap 15.4 Beta:openSUSE:linux:btrfs:UUID=b378b37c-b474-4172-9698-7ec0a8eb3708:subvol=@/.snapshots/1/snapshot
/dev/sda5:openSUSE Tumbleweed:openSUSE:linux:btrfs:UUID=00d53870-d313-43aa-9903-c4f9bedfbdd8:subvol=opensuse/.local/share/containers/storage/btrfs/subvolumes/3cc85ecbc13e520db01a88b36dbd581452a4aa7d317cd2cdb96a00b85243ee90

So the Leap 15.4 is still there. Grub just doesn’t show it.

  1. Even when specifying the exact path, it remains at “No such file or directory”. I then installed the individual rpm files from Brother for the printer and scanner. It did complain that the signature was missing, but I was able to ignore that. After rebooting, the printer and scanner work without any problems. I would prefer to install via executable script, but if that doesn’t work, that’s not so bad.

  2. Can you also help me with the WLAN?
    During installation I specify the WLAN connection and it is created as wlp3s0b1 without errors. But later in the running system no WLAN connection is established. I use WLAN now with the help of my smartphone, but this cannot remain a permanent solution. What can I do?

Hi
I suspect a bug report may be needed: openSUSE:Submitting bug reports - openSUSE

I’m assuming NetworkManager in use? If so, fire up nm-connection-manager and try that to see if connection can be configured.

Hi

No, I did not use NetworkManager, only KDE’s Network Manager. The settings on MicroOS are the same as the settings on Leap 15.3 on another device. The only difference is the name: On Leap 15.3: wlan0, on MicroOS: wlp3s.
I also installed NetworkManager and NetworkManager-connection-editor. But that did not help me.

:question:

That is a bit strange. Network Manager is a client server application. And what you see in KDE or any other desktop, is the client. The NM server runs in the background.

Hello,
I must apologize. It didn’t occur to me to check if the WLAN driver is installed at all. And it was not installed. Now it works.
Thanks again for the help with the other questions.
