Modem Manager GUI in Vera 21.1

[DooMFeaR]

Hi,

First of all, this will be my first post on this forum so I hope I post in the right section. I just switched from Ubuntu to Mint and I can't believe how much I enjoy it! I have a Dell E6230 with a SIM card in it. I used to have Modem Manager GUI installed and working under Ubuntu 20.04 LTS before switching to Linux Mint for sending text messages and also connecting to the internet when wifi was an issue.
In Mint 21.1, the Network Manager can see the modem hardware without any issue, I got network reception on the SIM card, and I can easily connect to the internet! I managed to install Modem Manager GUI through the terminal, but I have a problem when I am executing it. This is the error that I get:

Code: Select all

$ sudo modem-manager-gui

Can anyone give me some support here?

Thanks!!!

Run it without sudo. That program has nearly perfect reviews in Software Manager.

Hello, though being new to this forum, I can confirm that this also happens without sudo:

Thanks for reporting that. I created a review saying it does not work with LM 21.1.
