/usr/bin/gufw-pkexec: linje 13: 18732 Segmentfejl             (smed kerne) python3 ${LOCATIONS[${i}]} $1
klaus@klaus-HP-ProBook-4520s:~$

Hvad er der galt og hvad kan jeg gøre ved det?

Edit: Har lignende problemer med Synaptic og Nautilus


1) Segmentation fault

Følgende linie giver et hint om hvad der er galt:
/usr/bin/gufw-pkexec: linje 13: 18732 Segmentfejl (smed kerne) python3

En segmentfejl / segmentation fault er når et program tilgår hukommelse den ikke ejer.

Prøv at se om du får en nyere version af Python fortolkeren med:

Kode: Vælg alt

sudo apt update;sudo apt upgrade


Det er dog meget mere sandsynligt at seg faulten er sket i en Python pakke, der er kodet med C programmeringssproget.

Da en Python pakke bliver en del af Python programmet, så vil en segmentation fault i Python pakken se ud som om at det er Python fortolkeren/programmet der har lavet ged i det.

2) Gtk-Critical

Du skal (normalt) ikke bekymre dig om - og kan ikke gøre noget med en skærm meddelelse/log der indeholder Gtk-CRITICAL:

Eksempel fra dit indlæg:
Gtk-CRITICAL **: _gtk_replace_virtual_modifiers: assertion 'GDK_IS_KEYMAP (keymap)' failed

Gtk-CRITICAL meddelelsen er opstået på grund af en assertion. En assertion er en test som giver sandt (true) eller falskt (false), og her bliver den så true. CRITICAL er niveauet over fatalt, og fatalt får programmet til at crashe/gå ned.

Der er mange GTK+ programmer der skriver Gtk-CRITICAL

3) ufw i stedet for gufw

Du kan prøve at bruge gufw uden GTK+. Den hedder ufw, og er et terminal program.

Man kan med den her kommando læse at ufw er ...

Kode: Vælg alt

file /usr/sbin/ufw

... som svarer med:

Kode: Vælg alt

/usr/sbin/ufw: a /usr/bin/python3 script, ASCII text executable


... et Python 3 script, så det kan godt være at ufw seg faulter, men med lidt held er det kun gufw der er i udu.
