Hello there,

I tried to install MinKNOW on my ubuntu machine, but it kept fails. I got in trouble. Please help me. I followed instruction for installation on the nanopore community.

(1)

wget -O- https://mirror.oxfordnanoportal.com/apt/ont-repo.pub | sudo apt-key add -

I ran this command and it showed this,

https://mirror.oxfordnanoportal.com/apt/ont-repo.pub

Resolving mirror.oxfordnanoportal.com mirror.oxfordnanoportal.com)... 99.86.144.116, 99.86.144.9, 99.86.144.110, ...

Connecting to mirror.oxfordnanoportal.com mirror.oxfordnanoportal.com)|99.86.144.116|:443... connected.

ERROR: cannot verify mirror.oxfordnanoportal.com's certificate, issued by ‘CN=ePrism SSL,O=SOOSAN INT,C=KR’:

Self-signed certificate encountered.

To connect to mirror.oxfordnanoportal.com insecurely, use `--no-check-certificate'.

gpg: no valid OpenPGP data found.

Hence, I used '--no-check-certificate' option and it worked.

(2)

echo "deb http://mirror.oxfordnanoportal.com/apt bionic-stable non-free" | sudo tee /etc/apt/sources.list.d/nanoporetech.sources.list

I ran this, and it was OK.

nanoporetech.sources.list file successfully created.

Here's the problem!!!!

sudo apt-get update

I ran this command, and I got this below.

Ign:1 https://mirror.oxfordnanoportal.com/apt bionic-stable InRelease

Err:2 https://mirror.oxfordnanoportal.com/apt bionic-stable Release

Certificate verification failed: The certificate is NOT trusted. The certificate issuer is unknown. Could not handshake: Error in the certificate verification. [IP: 99.86.144.110 443]

E: The repository 'http://mirror.oxfordnanoportal.com/apt bionic-stable Release' does not have a Release file.

N: Updating from such a repository can't be done securely, and is therefore disabled by default.

N: See apt-secure(8) manpage for repository creation and user configuration details.

There's certificate issue. How can I solve this?

I tried to update, reinstall ca-certificates..also I tried to add [trusted=true] in nanoporetech.sources.list file..

anything works......

Any suggestion??

Thanks,

See this stackexchange answer. A workaround is to run

apt-get update -o Acquire::https::mirror.oxfordnanoportal.com:apt::Verify-Peer=false

I'm not using Debian so I can't verify my format of https://mirror.oxfordnanoportal.com/apt in the above command is correct. Someone else care to chime in the proper format?

Thanks for your comment. Unfortunately, it was not working. It showed exact same result with just apt-get update. Same certificate issue.

you could try apt-get update -o Acquire::https::mirror.oxfordnanoportal.com/apt::Verify-Peer=false or apt-get update -o Acquire::https//mirror.oxfordnanoportal.com/apt::Verify-Peer=false

otherwise run a websearch for Certificate verification failed: The certificate is NOT trusted. The certificate issuer is unknown. Could not handshake: Error in the certificate verification
