I update my kali linux and after updating none of the snap softwares are working, I uninstall snapd, snap and install it again but still the same problem.
Thanks for reporting this. Did you follow the installation instructions?
Specifically the bit about
systemctl enable of specific services.
If that does not help, please run
SNAPD_DEBUG=1 snap run <snap>.<app> in the terminal and attach the output (eg.
SNAPD_DEBUG=1 snap run ohmygiraffe)
yes, I follow these instructions, the problem is the snap apps was working perfectly before updating the system, After the kali linux new update no app is working.
Can you check what was part of that system update? Was snapd updated as well?
no it was only system update.
