Error modprobe.d

hello everybody,

I get this error at startup:

ERROR: kmod_config_parse: /etc/modprobe.d/disable-algif.conf

nano disable-algif.con exit:
install algif_aead/bin/false

test:
lsmod | grep algif_aead

test:
rmmod algif_aead
Module algif_aead is not currently loaded
Unable to find the algif_aead package

Does anyone have a solution to fix this

regards,

Re: Error modprobe.d

Here are tips by AI. Please check them and post back the result.

---
AI generated:

A likely cause is that the line in `/etc/modprobe.d/disable-algif.conf` is malformed. `kmod_config_parse` errors usually indicate a syntax problem in a `modprobe.d` configuration file.

The error suggests that `/etc/modprobe.d/disable-algif.conf` contains an invalid `modprobe` configuration.

Please check the file with:

```bash
cat /etc/modprobe.d/disable-algif.conf
```

The line should be:

```text
install algif_aead /bin/false
```

Notice the **space** between `algif_aead` and `/bin/false`. If your file contains:

```text
install algif_aead/bin/false
```

it is missing that space, which would produce the `kmod_config_parse` error.

After correcting the file, reboot or simply test the configuration with:

```bash
sudo modprobe -n -v algif_aead
```

Regarding:

```bash
rmmod algif_aead
Module algif_aead is not currently loaded
```

this is normal—it only means the module isn't currently loaded.

Also, `algif_aead` is a **kernel module**, not a Debian package, so there is no package named `algif_aead` to install.

If the configuration file already contains the correct syntax, please post the output of:

```bash
cat /etc/modprobe.d/disable-algif.conf
grep -R algif_aead /etc/modprobe.d/
```

so we can investigate further.

Re: Error modprobe.d

Hello everybody,

The requested result :
cat /etc/modprobe.d/disable-algif.conf
install algif_aead/bin/false

Amended text :
nano /etc/modprobe.d/disable-algif.conf
cat /etc/modprobe.d/disable-algif.conf
install algif_aead /bin/false

sudo modprobe -n -v algif_aead
insmod /lib/modules/7.1.5-2-liquorix-amd64/kernel/crypto/af_alg.ko.zst
install /bin/false

cat /etc/modprobe.d/disable-algif.conf
grep -R algif_aead /etc/modprobe.d/
install algif_aead /bin/false
/etc/modprobe.d/disable-algif.conf:install algif_aead /bin/false

Testing again same error :
lsmod | grep algif_aead
rmmod algif_aead
rmmod: ERROR: Module algif_aead is not currently loaded

regards,

Re: Error modprobe.d

Please post the output of:

$ sudo find /etc/modprobe.d /usr/lib/modprobe.d /lib/modprobe.d -type f -exec grep -H "algif_aead" {} \;
$ sudo update-initramfs -u
$ journalctl -b | grep -i kmod

Also, please copy the exact startup error message as it appears now (or attach a photo).

Re: Error modprobe.d

The previous syntax error has definitely been fixed:

modprobe -n -v algif_aead recognizes the install /bin/false rule.
update-initramfs -u completed successfully.
No kmod parse errors appear in the system journal.

The remaining message shown on the splash screen is therefore unexpected. It may be caused by hidden characters (for example, Windows line endings or an invisible UTF-8 character) in the configuration file.

Could you please post the output of these commands?

$ cat -A /etc/modprobe.d/disable-algif.conf
$ file /etc/modprobe.d/disable-algif.conf
$ hexdump -C /etc/modprobe.d/disable-algif.conf
$ modprobe -c | grep -A2 algif_aead

One more question: did you create disable-algif.conf yourself, or was it installed by a package or a script? If you know which package or tutorial created it, that information may help identify the cause.

Re: Error modprobe.d

Hello everyone,

I went through everything again from the beginning, step by step, to see if I had made a mistake somewhere, and it worked.
The error has disappeared, though I don't know how.
Thanks for your help.

Here is what was requested :
cat -A /etc/modprobe.d/disable-algif.conf
install algif_aead /bin/false$

file /etc/modprobe.d/disable-algif.conf
/etc/modprobe.d/disable-algif.conf: ASCII text

hexdump -C /etc/modprobe.d/disable-algif.conf
00000000  69 6e 73 74 61 6c 6c 20  61 6c 67 69 66 5f 61 65  |install algif_ae|
00000010  61 64 20 2f 62 69 6e 2f  66 61 6c 73 65 0a        |ad /bin/false.|
0000001e

modprobe -c | grep -A2 algif_aead
install algif_aead /bin/false
options snd_pcsp index=-2
options cx88_alsa index=-2

No, I didn't create this file; I think it appeared during an update, but I couldn't say when or which one.

regards

Re: Error modprobe.d

Thanks for letting us know you solved that. That seems to have connection to Liquorix kernel, it's not Debian/Q4OS standard one.

Re: Error modprobe.d

I think it's related to the KDE Application Platform, because in a previous post back in June, I mentioned that the update wouldn't go through due to Tor—which I had to uninstall in order to perform the update.

Re: Error modprobe.d

Yes, all those odd issues may be connected to Liquorix kernel or another non standard elements added. We have no similar reports or indicator that this issue may arise on the default Debian/Q4OS setup. All in all, we are glad it works for you now
