Cannot open seccomp filter: permission denied when installing snap

Please fill out the fields below so we can help you better. Note: you must provide your domain name to get help. Domain names for issued certificates are all made public in Certificate Transparency logs (e.g. |, so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.

Domain name doesn't really matter since I can't install certbot but since it's required:

I ran this command:
sudo snap install --classic certbot

It produced this output:

error: cannot perform the following tasks:
- Run configure hook of "certbot" snap if present (run hook "configure": cannot open seccomp filter /var/lib/snapd/seccomp/bpf//snap.certbot.hook.configure.bin: Permission denied)

The operating system my web server runs on is (include version): Ubuntu 20.04 LTS focal

Welcome to the community @3nt3

I have no ideas about this error. It is rare. I see you already posted on certbot github. That is a good approach for this error and already got one response from a certbot dev. Hopefully you will get an answer there or maybe here from someone else.

I wanted to add that certbot is not the only ACME client. The script is very popular and many acme clients are in the Let's Encrypt client list.


@3nt3, did you completely follow the installation instructions?


@rg305 yes
