Hello. I encounter such an error during the initial installation phase. How will I get over this? I’m trying to install it on Debian 11 vps.

I found a solution. I opened this file,

sudo nano /etc/apt/sources.list

I added these two lines at the top.

deb http://deb.debian.org/debian bullseye main
deb-src http://deb.debian.org/debian bullseye main

The installation is now up and running.

Hi ersingo,

Great that you found a solution!

The lines that you added on top should have been in that file, if your VPS is running version 11 (Bullseye) of Debian.

If those lines were missing, maybe you like to compare the remaining lines as well. My Yunohost got those :

  • /etc/apt/sources.list
    deb http://ftp.debian.org/debian bullseye main contrib deb http://ftp.debian.org/debian bullseye-updates main contrib deb http://security.debian.org bullseye-security main contrib
  • /etc/apt/sources.list.d/yunohost.list
    deb http://forge.yunohost.org/debian/ bullseye stable
  • /etc/apt/sources.list.d/extra_php_version.list
    deb https://packages.sury.org/php/ bullseye main

The bottom two files are in the subdirectory /etc/apt/sources.list.d/

Good luck!
