When I use the command journalctl -b | plasma grep it showed a series of errors, can someone tell me what these errors are and how to fix them?

Please use [code][/code] tags. Edit your post in this regard.

jun 28 15:24:18 archie sddm-greeter-qt6[601]: Reading from "/usr/local/share/wayland-sessions/plasma.desktop"

Can you please explain how this is an error message?
Also most of this is plain english - https://deepl.com/

Well, this here isn't english:

jun 28 17:06:07 archie plasma-discover[7129]: org.kde.plasma.libdiscover: error loading "packagekit-backend" "Não foi possível carregar a biblioteca /usr/lib/qt6/plugins/discover/packagekit-backend.so: libpackagekitqt6.so.1: não é possível abrir arquivo compartilhado: Arquivo ou diretório inexistente" QJsonObject({"IID":"org.kde.discover.6.4.1.AbstractResourcesBackendFactory","archlevel":1,"className":"PackageKitBackendFactory","debug":false,"version":395520})
jun 28 17:06:07 archie plasma-discover[7129]: org.kde.plasma.libdiscover: error loading "fwupd-backend" "Não foi possível carregar a biblioteca /usr/lib/qt6/plugins/discover/fwupd-backend.so: libfwupd.so.3: não é possível abrir arquivo compartilhado: Arquivo ou diretório inexistente" QJsonObject({"IID":"org.kde.discover.6.4.1.AbstractResourcesBackendFactory","archlevel":1,"className":"FwupdBackendFactory","debug":false,"version":395520})

it's the closest thing to an "error" in your output, I guess you can read it?

Re: [SOLVED] I use the command journalctl -b | plasma grep it showed erros

Unless you notice active issues your best bet is to ignore most of these. Some issues are likely stuff logically running a bit too early because it gets started in parallel and some screen information not being ready yet. the fwupd error is because you didn't install the optional fwup dep for discover also not really cause for concern.

Please wrap outputs in  [code][/code] tags in the future

Re: [SOLVED] I use the command journalctl -b | plasma grep it showed erros

I can actually read that - the point is that this is still not really an error (see V1del's comment) - nor is anything else you posted.
