CrowdSec doesn't install - Cannot create task get-name

hucky · May 11, 2024, 12:33pm

i reinstall the whole ns8 system because of root disk full, this is fine now. But if i try to install crowdsec i got an error

the service did not start. Logs says:

it is also not possible to deinstall, because the system says it is not installed… weird

Any ideas?

mrmarkuz · May 11, 2024, 2:02pm

Is it really still installed? Maybe the browser page needs to be reloaded…

Maybe it’s possible to uninstall from CLI:

remove-module --no-preserve crowdsec1

There’s also a force option but dangerous:

--force        unconditionally erase the module from Redis (dangerous)

To be able to understand what’s going on we also need logs from the cluster at time of (un)installation.

It seems the uninstall fails because of a missing service.

Are there still crowdsec services?

systemctl status crowdsec*

I don’t know if it’s the right way but when crowdsec2 is working and you have a backup/snapshot you could try to force the removal of crowdsec1.

remove-module --force --no-preserve crowdsec1

hucky · May 12, 2024, 9:53am

also no luck
remove-module --force --no-preserve crowdsec1

mrmarkuz · May 12, 2024, 10:10am

Are the service files still there?

ls -l /etc/systemd/system/crowdsec*

hucky · May 12, 2024, 10:40am

ls -l /etc/systemd/system/crowdsec*

mrmarkuz · May 12, 2024, 3:42pm

The service files are missing, the timer is still there.

root@contabo:~# ls -l /etc/systemd/system/crowdsec*

Maybe it helps to recreate the missing file(s) and try to uninstall again?
The file content can be found on GitHub.

This also did not work, i try a new installation and see how it works

dnutan · May 13, 2024, 8:43am

Didn’t read fully but deleting crowdsec1 user and its home folder could be another option.
EDIT: ok, possibly won’t work with a rootful app

hucky · May 13, 2024, 8:48am

tried it all but did not work, so i decide to delete the installation and renew the server, now its fine
