[SOLVED] Package install problem

[FellGleaming]

In my earlier (solved) problem, I performed a core-only minimal Debian 11 install, as network services (and the Debian mirror) were unavailable at that time. After fixing the nic issue and configuring the network, I'm now trying to install some packages and convert this to a full-blown installation. I first did:

Code: Select all

apt install tasksel

And was told tasksel was already up-to-date. Running tasksel with no parameters gave no output whatsever. Running:

Code: Select all

tasksel ---new-install

Gave me an options screen, but the only package available to install was "standard system utilities", and already marked installed. I then tried to use apt, naming several packages by name. No matter what I tried, apt could not find any.

I then edited apt's "sources.list" file, to add back in two lines that the installer had commented out:

Code: Select all

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

I removed the comment marker from the above lines, then did an "apt-get update" to update apt's cache. This completed OK, but apt still can't find any packages. I then examined the cache file(s) for apt at /var/lib/apt/lists. The two relevant files seem to be:

Code: Select all

deb.debian.org_debian_dists_bullseye_updates_main_binary-amd64_Packages
security.debian.org_debian-security_dists_bullseye_security_main_binary-amd64_Packages

These are the only files ending in "Packages" and both were updated by the apt-get update cmd. The security file has a fair amount of stuff in it, but the main Package cache only shows packages relating to "Clamav".

Did I do something wrong in manually configuring apt? Are there more lines I need to add to sources.list?

Have a look at the example sources list here:

https://wiki.debian.org/SourcesList#Exa ... urces.list

Do you have the actual package repository? Do you have the security repository? You may not need src (source code). You may want to add contrib and non-free.

Running

Code: Select all

# tasksel

should give you the GUI.

I had the src, security, and update repositories, but not the main itself. Adding that line solved the issue. Thanks for all the help.
