What does it mean? How i can solve it?
Thank you

Go to module admin and update all your modules.

if i try to update all my modules i receive some errors…

care to share the errors

for example this is one error:

This is the list with all update available but i have 3 rows with background in orange…

what i can do? :frowning:

Update at the CLI with

fwconsole ma upgradeall

i have to paste your command?
or i have to launch before asterisk?

Because i paste your command in putty and i receive this message

other help is possible? :frowning:
