Problem with install snap package

/var/lib/snapd/snap/bin was not found in your $PATH. If you’ve not restarted your session
since you installed snapd, try doing that. Please see How to fix snap binaries not found
for more details.

How I can fix this?

I cant find info about it on this page

did you follow the advise and restart your session (i.e. log out and back in again or reboot) ?

I I have restarted my computer many times. Did not help

what is the full output of snap version and do you use some special non-default shell as your login shell ?

snap 2.49.1-1
snapd 2.49.1-1
series 16
manjaro -
kernel 5.9.16-1-MANJARO

And I am using fish…

that might be your issue (i think i remember there were issues with fish not respecting the environment proper)

Hmmmm… It is strange. I changed my shell to bash and all began working.

i did some googling, perhaps this helps ?
