I am having similar issues here. Tried the following commands unsuccessfully as well
sudo runuser -u gvm –- gvmd --create-user=admin --new-password=“newpasswordhere”
sudo runuser -u gvm –- gvmd --create-user=admin --new-password='newpasswordhere'
sudo runuser -u gvm –- gvmd --create-user=admin --new-password=newpasswordhere
sudo runuser -u gvm –- gvmd --create-user="admin" --new-password=“newpasswordhere”
sudo runuser -u gvm –- gvmd --create-user='admin' --new-password='newpasswordhere'
sudo runuser -u gvm –- gvmd --create-user=admin --new-password=newpasswordhere
even with the single - before gvm ddidn't work at all.

Also the following is not working too
gvmd --user=admin --new-password=newpassword

When using gvmd to change a user password I can see the value changes in the database but the web UI will not log in with the new password.

I've performed a clean fresh install of kali 2022.3. After the fresh installation is complete, I did a sudo apt update && sudo apt full-upgrade. Once the upgrade is finished, I setup gvm again and I noticed at the completion of the setup, there is no password created at all.

Created new VM, installed 2022.3, update and full-upgrade, installed gvm. Ran gvm-setup. When it attempts to crete the admin user the error "Failed to create user: Invalid characters in user name" is thrown. Attempts to create another admin user fail with the same message. gvmd --get-users shows no users. gvmd --get-roles shows seven roles.

monitored /var/log/gvm/gsad.log:
gsad main:MESSAGE:[DATE] Starting GSAD version 21.4.4
gsad gap:WARNING: [DATE] Authentication failure fro '' from 127.0.0.1

gsad was not changed during last update of kali, but what was that is causing this error?

I'm having the exact same problem on an old install that’s been running for years, after applying the updates from a couple of days before.
The webgui sends an empty string instead of the username, throwing an “Authentication failure for ‘’ from x.x.x.x” warning in /var/log/gvm/gsad.log. Note the '' in the error (empty string between single quotes).
Trying to create a new user fails with "illegal characters in user name", no matter the username.
Apparently, the strings aren't treated correctly, like double quoting or something.

same here after update of kali linux and reboot greenbone login do not recognize the right id and password...absurd.
cannot understand how to solve...wtf...I have 80 scann there and need to use it

maybe this could help it seems the same issue solved with postgresql one year ago I'll try it tomorrow

https://bugs.kali.org/view.php?id=6764

Does not appear to be related to postgres clusters as a new install fails like an existing upgraded installation,
Output of pg_lsclusters on new and old:

Ver Cluster Port Status Owner Data directory Log file
14 main 5432 online postgres /var/lib/postgresql/14/main /var/log/postgresql/postgresql-14-main.log

Seting log level to debug for gsad shows that password matches in gvm_validate but username does not.

Log snippet won't upload regex that attempt to match username from gsad.log
Matching ^[[:alnum:]-_@.]+$ against <admin>:

gvm-cli is able to log in and retrieve tasks

sudo runuser -u _gvm -- gvm-cli --gmp-username admin --gmp-password itsasecret socket --xml "<get_tasks/>"

I can support baikal’s notes, tried that myself yesterday with the same results.
The root seems to be in gsad and one of the components.
Assumed find it in microhttpd, but it was updated one month ago and not during the last days.

I did everything to solve the problem all day yesterday and I also asked the stackoverflow with all the details:
https://stackoverflow.com/questions/73771170/no-users-found-openvasgvm-setup-error
Today is the same. I am trying to setup also on ubuntu, there are other tons of problems there.

There is a thread in the Greenbone forum related to this exact issue:
https://forum.greenbone.net/t/kali-cant-create-gvm-user-throws-an-error-failed-to-create-user-invalid-characters-in-user-name/13062/38

Someone suggested the culprit might be in glib, but I would expect a lot more to break down from such a bug, not just GVM.

I also posted in the Greenbone with the detail. They directed to here. It is related to Kali for sure.
https://forum.greenbone.net/t/no-users-found-gvm-setup-on-kali-linux/13073

If you need urgent like me, I think the only solution is to install old releases o kali. http://old.kali.org/kali-images/ They said 2022.2 is ok, try it.

The thing is that we CAN NOT WORK; as simple as that...

I installed 2022.2 on VirtualBox and just did apt-get update -y, not upgrade.
Then apt install openvas, gvm-setup, gvm-feed-update. At this point, I was able to access via browser and in the browser web GUI> Administrator - Feed status should be completed because it is also updating there and then it is good to go!

but U lost your previous work (tasks etc)?
I need to have access to 80 scanner locked for this absurd issue
tried also from another computer configuring the ip everything goes but the login

I have reinstalled on kali 22.3 and gvm work login also there but with new install.....how Can I recap my scann...from the other account?

Thanks the report

I confirm the issue.
It seems to be caused by the package libglib2.0-0 version 2.73.3-3. If I re-installed the previous version 2.72.3-1, it fixes the issue. To re-install the old version is not a valid fix (it removes several packages depending on the latest version and it may create other issues).

I will work on a real fix.

new issue I have reinstall from zero gvm in wmn kali 22.2 intallation is ok but no scanner in it, same on kali for raspberry pi
check setup tell everything is. ok but in both version thhis problem comes of without a cause wtf hours and hours lost on it

I was hoping that the new version 2.74.0 (already packaged in Debian Unstable) would fix the issue, but it doesn't.

I reported the issue to upstream:
https://gitlab.gnome.org/GNOME/glib/-/issues/2760

Thanks for your efforts!

I have just uploaded a fixed version of gvmd (21.4.5-1kali1). It will be available soon.

@sbrun Awesome. Thanks.

@sbrun, thanks! I'll check it out!

@sbrun Tried it this morning after it was available, I sorry that I have to say, that it did not fix the issue.

@grisutheguru I tested the new version and I was able to create new users, change passwords without issues.
Can you give me details about the commands you run ?

Hello sbrun and thank you again for your efforts. Does the new version work normally with the existing admin pass?

I don't have an "old" installation of gvm to test if it works with the existing admin pass but I think it works: the patch only concerns a format check of the username.

@grisutheguru maybe you should try to restart gvmd.service

Hi,

same issue here. i updated the application. I can reset the password and create new users but cannot login to Web.

@sbrun: I did full reboot to be on the safe side

What I did:
apt update
apt -y full-upgrade
reboot

gvm-start

tried to log in —> failed
tail -f /var/log/gvm/gsad.log —> showed that error message as it was before with ‘’ as username

sudo -runuser _gvm — gvmd —user=grisu —new-password=****

restarted gvmd

tried to log in: failed, checked logs, same entry as before

Hi,

same issue here...

FWIW: the login issue is also caused by the new liglib2.0.

LIke others I'm still unable to log in through the web UI after update, full-upgrade, and reboot. The same regex + authentication failure appears in the gsad log

matching ^[[:alnum:]-_@.]+$ against <admin>:
gvm_validate: failed to match
Authentication failure for '' from 192.168.168.16

dpkg -l gvm*
ii gvm 21.4.4~kali1 all remote network security auditor - metapackage and useful scripts
ii gvm-tools 22.6.0-1 all Remote control the Greenbone Vulnerability Manager
ii gvmd 21.4.5-1kali1 amd64 Manager Module of Greenbone Vulnerability Manager
ii gvmd-common 21.4.5-1kali1 all architecture independent files for Greenbone Vulnerability Manager

Copying for GVM forum:

• GLib seems to throw a warning / error on such incompatible regex calls after gregex: Use pcre2 error messages if we don't provide a specific one (!2913) · Merge requests · GNOME / GLib · GitLab has been released so that such incompatibilities are more visible.
• In Kali it seems that the regex was now made PCRE2 compatible via a newly published patch: 0007926: Unable to log in to greenbone after full upgrade and reboot - Kali Linux Bug Tracker.

I uploaded gsad version 21.4.4-1kali1 (same cause and same regex issue as fixed in gvmd)

Please install the latest version of gsad.

Hi,
i updated but now web not working :(

ERR_CONNECTION_REFUSED

@sbrun Ability to login restored with gsad update. Thanks. :fireworks:

So, I just update - upgrade KALI and everything works fine?

@leontiosp I did
sudo apt-get update && sudo apt-get full-upgrade -y ; sudo systemctl restart gsad.service

Thanks! Now Working!

Dude! You rulez! All is working now, thanks for the quick resolution!

Unfortunately, my system doesn't login.
I did sudo apt-get update && sudo apt-get full-upgrade -y
NUT neither the saved Admin password or the new user I created doesn't make it through :(

NOT only my existing Admin password VALIDATES, but also the new user I created won't pass through:

sudo runuser -u _gvm -- gvmd --create-user=PL --new-password=pl1314362021
User created with password '21ce23bf-c071-485a-a472-6b2a0e0365a5'.

sudo runuser -u _gvm -- gvmd --create-user=PL1 --new-password=new_password
User created with password '8805fcf2-f9bf-4fd8-b058-158b2ad8d214'.

For instance:
User: PL1
Pass: 8805fcf2-f9bf-4fd8-b058-158b2ad8d214
NOT WORKING

Any ideas?

Thanks...

@leontiosp please first check that you have the latest gsad installed:

dpkg -s gsad

You need version 21.4.4-1kali1.

If you have the version 21.4.4-1kali1, please check the log of gsad: /var/log/gvm/gsad.log

If needed, you can have more info in the log by changing the config log /etc/gvm/gsad_log.conf. You can change the level, see /usr/share/doc/gsad/README.md.gz. If you change the "level", I think you will have to restart gsad.service to apply the changes.

First of all, thank you for your response.

My gsad version (although I did full update - upgrade of KALI) is: 21.4.4-0kali4 and NOT 21.4.4-1kali1.

How do I get the right version?

http.kali.org/kali/pool/main/g/gsad/gsad_21.4.4-1kali1_amd64.deb
dpkg -i gsad_21.4.4-1kali1_amd64.deb

Thank you for your help!
However, the right version came with the latest update - upgrade its self!

The login WORKED eventually.

I managed to get in.

BUT there is problem with gsad service ...

the check setup wrote:
ERROR: gsad service did not start.
Please check journalctl -xe and /var/log/gvm/gsad.log

Just a single line from /var/log/gvm/gsad.log as asnwer:

gsad gmp:MESSAGE:2022-09-21 18h12.18 utc:1844: Authentication success for 'grisu' from 127.0.0.1

thanks a lot!

Thanks so much- i'm in.
"sudo apt update" and "sudo dist-upgrade" grabbed your new file 21.4.4-1kali1 and updated my system perfectly.

Thanks for the fix @sbrun !

Thank you!!! Everything is OK now...

I am able to create a user and gvm-check-setup gives no error! Bravo, thank you!

Sounds like its all sorted - closing!
