Output from os-prober showing non existent entries

I get this output when installing packages from Pamac:

Found Manjaro Linux on /dev/mapper/luks-95a9c47a-ede8-438c-a436-9e117a7636a9
Found Debian GNU/Linux 10 (buster) on /dev/mapper/luks-95a9c47a-ede8-438c-a436-9e117a7636a9

How do remove the entries under Manjaro?

2

please change title ! it’s not pamac

grub (or other ?) found some linux and you want remove theses entries

It’s at you to uninstall these linux (remove theses partition…)

3

The problem is that those partitions don’t exist.

4

I guess it’s the result of os-prober while updating grub during kernel update.

I fail to see the real issue here.

5

Problem is that those installs don’t exist.

6

Type here the result of sudo os-prober.

ok,

thes linux are in docker

9

I do not use docker anymore. How do I remove them?

Is os-prober even supposed to run after every package installation?

10 
docker ps;  docker rm XXX  [ docker images ; docker rmi YYY ]

os-prober run after all kernel update

11

os-prober runs for me on every package transaction.

12

After each kernel update, it does sudo update-grub that you can also launch manually.
Within grub config, you get os-prober that is launched alongside.

As @papajoke said, it’s only for kernel related updates, so not as often that regular packages.

Edit: do you complete the update of all the packages? Or do you perform partial updating?

13

complete update

14

I don’t use either encryption, nor docker. I don’t know what happens during updates then.

If not using it anymore, I’d flush the docker containers (no idea how, though).

15

me to :rofl: GNU GRUB - Bugs: bug #53688, os-prober found dockers conteners... [Savannah]

I had an archlinux in /dev/sda10 (btrfs)
os-prober couldn’t find my archlinux but find my containers :upside_down_face:

16

If it wasn’t fixed since 2018 it probably won’t be fixed anytime soon.

17

Btrfs, LUKS, Docker…
Winning combo.

18

Not even close. Throw in a laptop with WiFi, hybrid AMD/Nvidia graphics, a touchpad, a Bluetooth dongle, a dual-boot setup with Windows 11, and a n00b who likes hardcore gaming through Steam and Lutris on triple monitors with a HDMI connection, and then you’ll be closer to winning the prize. :rofl:

But of course, btrfs with Docker containers on LUKS is a good start. :stuck_out_tongue:

19

I had no docker containers, volumes or images installed. Seems that os-prober was picking up the btrfs snapshots. I just removed the offending snapshots.
