Seems Snap of cerbot classic needs an update

I got this error today on Debian 11 Bullseye:

cannot snap-exec: cannot exec "/snap/certbot/2836/bin/python3": no such file or directory

Looking, the file is there, but appears to be a symbolic link.

lrwxrwxrwx 1 root root 20 Mar 7 21:46 python3 -> ../usr/bin/python3.8

Looking in /usr/bin there is no python3.8, however python3.9 does exist.

Would it be okay to delete that and change it to python3.9?

‘snap list’ please.


Name Version Rev Tracking Publisher Notes
certbot 2.4.0 2836 latest/stable certbot-eff✓ classic
core 14946 latest/stable canonical✓ broken
core20 1852 latest/stable canonical✓ broken

I don’t have access to a computer at the moment but I’d try

snap revert core
snap revert core20


error: cannot revert "core": no revision to revert to

error: cannot revert "core20": no revision to revert to

Is this a brand new installation or did it break recently?

I won’t be able to check this for another 8 hours or so but I don’t think there’s a lot you can do except try remove all the snaps in reverse order and try reinstall them.


This is a new installation.

Your suggestion of removing and re-installation worked out.

Thank you kindly for your assistance, and time helping!
