Glances 4.4.0 On Ubuntu 24.04: Error while initializing the ports plugin (module 'netifaces' has no attribute 'default_gateway')

[gbonazzoli]

Describe the bug

At the startup of Glances 4.4.0 On Ubuntu 24.04 we get:

Error while initializing the ports plugin (module 'netifaces' has no attribute 'default_gateway')

Glances then starts normally, and from the TUI I've not seen anything abnormal.

Sorry,

the solution is also written in the log file.

The problem can be solved with a simple: pip install --break-system-packages Netifaces2
