Beginner troubles with pacman update and the configuration of a LTE modem.

Hello !

I am new to Artix Linux (did not use Linux for a very long time) and run in some troubles. I tried the lxqt-runit / -openrc and the plasma-community edition from the download page. I experienced that the lxqt-runit / -openrc (including the gremlin version) randomly freezes the machine at shutdown and reboot but it is not reproduceable which is not really a problem as I used for some days a installation of the plasma-community edition.

My first problem is, if I run pacman -Syu (followed the suggestions at first run) after the installation, I get at the integrity check of the packages the error, that 4 packages (IIRC mypaint) can´t be checked (plasma-community edition) and in the lxqt-runit / -openrc edition that 1 key (IIRC qpdfview) is deactivated. In booth cases a update was not possible (some days before I had no problem in the plasma-community edition to update the system). How can I run pacman to install only the already downloaded packages where the integrity check was passed and, how I fix the key problems ?

The second thing is, I can use in the lxqt-runit / -openrc edition a LTE modem (m.2 Sierra EM7345). During boot it is basically configured for the carrier. After running the assistent to configure it, I can use it without problems. My question is now, how can I configure the LTE modem in the plasma-community or the gremlin version as the GUI is very different ?

Thanks for help.

1. Try to first update archlinux-keyring package
Code: [Select]
pacman -Sy archlinux-keyring
and than update normally (seems like classic Arch error)

2. That is matter of GUI which I am not very familiar with, I would suggest to use same GUI (was it connman or networkmanager now?)

Thanks for your answer. Sorry for the delay but my connection yesterday was not that fast to download the updates again on a clean install.

1.) Yes, updating archlinux-keyring helps in booth cases. On the plasma edition without any action, on the lxqt-runit edition with deleting /etc/artix-release (which only contains the text - artix release).

2.) networkmanager with the KDE applet. I found some articles about this medoems to try out (just installed modemmanager, mobile-broadbad-provider-info and nm-connection-editor but did not try the rest - was to late yesterday).

BTW after updateing the machine I have also the random freezes at shutdown. As it is a ThinkPad W541 with nVidia optimus and I don´t have the machine here, I will post later informations using inxi.

I had no luck with the modem using the plasma-community edition and will use the lxqt edition and install plasma or something else as the modem already works.

Beside that, the machine freezes randomly (at restart, shutdown, after screenlock ... ). But not during boot or login.

I've got a same CPU/GPU laptop (Dell M4800 i7-4810MQ/K2100M), and had some freezes with kernel 5.4 without even using the nouveau or nvidia drivers. I actually regretted (killed an uptime of 84 days) updating from 4.20 and downgraded again a couple of days later: rock solid again, 15 days uptime and counting.

For me only the 4.18.12 from the plasma-community .iso works without problems. The 4.20.10 from the lxqt-gremlins .iso and the 5.4 did not ... if it is the kernel.

I would suggest checking if linux-lts kernel works.
The reason being it is kept up to date.

Yup, LTS kernels are better for peace of mind and stability.

Tried for some days the lts kernel which works.
Was curious too and installed the plasma edition again. Then the machine only freezes at the reboot of the live system (after installation).

As that worked now, any suggestions for the configuration of the LTE modem in the plasma edition are welcome.
