The topic says that update for Webmin and Virtualmin is not possible, and as it is most likely repo mis-configuration issue, my suggestion should just fix the repos, so it will be later possible to just run apt-get upgrade to install latest Webmin and Virtuamin packages.
[root@srv ~]# apt-get clean && apt-get update && apt-get upgrade

Certbot can obtain and install HTTPS/TLS/SSL certificates. By default,
it will attempt to use a webserver both for obtaining and installing the
certbot: error: unrecognized arguments: Alternative//110329_10539_3_letsencrypt.cgi --os_type ‘debian-linux’ --os_version ‘11.0’ --real_os_type ‘Ubuntu Linux’ --real_os_version ‘20.04.3’
Do you know what it could be. One Cert after the other is loosing validation and the first of my clients is asking why he is getting a cert error in outlook.
What the heck did you do to your system? That’s just bizarre. Like, I’m having a hard time imagining how this could happen.
You’re going to need to find where that’s coming from. I can’t guess.
I’d start with this to try to find it: sudo grep -R 'Alternative/' /etc/
That may or may not find a clue. Maybe it’s something in profile or bashrc. Maybe it’s something else. It’s weird as hell, whatever it is. I don’t know how you’d make it appear on every command line like that.
Thanks for your prompt feedback and help. I don’t hack around on servers I don’t know well, especially on servers with client accounts. I set up the server about a year ago and the only thing I did was doing the updates that webmin/virtualmin advised me to do and about a month ago I started to get the message that the Lets Encrypt certificates validation couldn’t be prolonged. The same error message I posted here.
I found it. We had the same idea. I set it back to default. I remember that we had some problems making scheduled Virtualmin backups because the partition got out of space. Then we changed it as a workaround till we found a solution for the problem. And as usually, if you don’t do it immediately right, you will never do it right. Is it really a problem changing it? Do I have to consider something when I change it?
