How to find the URI and repository name from which the package was installed?

verilog15 · 07-02-2021, 09:57 AM

Hello!
My task is to do the following: Build a script which, given a list of rpm packages, finds all the zypper repositories (name and URIs).

I have a package installed locally and I want to find the zypper URI and the repository name from which the package was installed from. I could search for the package and find it:

Code:

zypper info $PKG_NAME

It does give me the repo name (if there is one) but it does not give me the URI:

Code:

> zypper info tcsh
Information for package tcsh:

Repository: <REPO_NAME>
Name: tcsh
Version: 6.18.01-9.7.1
Arch: x86_64
Vendor: SUSE LINUX Products GmbH, Nuernberg, Germany
Support Level: unknown
Installed: Yes
Status: up-to-date
Installed Size: 1.0 MiB
Summary: The C SHell
Description:
Tcsh is an enhanced, but completely compatible, version of the Berkeley
UNIX C shell, csh(1). It is a command language interpreter usable as an
interactive login shell and a shell script command processor. It
includes a command-line editor, programmable word completion, spelling
correction, a history mechanism, job control, and a C-like syntax.

I want the "Repository:" part.

I'm also familiar with the

Code:

zypper repos -u

command to list all the repositories and URIs.

I could combine the two commands and find the repository name and then the URI. Is there a better approach? My biggest struggle is on how to parse it. So the questions are:
1. Is there a command that given the package name, returns the repository name (without the need to parse)?
2. Is there a command that given the package name, returns the repository URI (without the need to parse)? Is it possible to combine it with question 1 and just get those two?
3. If there is no way to get the repository URI based on the package name, is there a command to get the repository URI based on the repository name (without the need to parse)?

Maybe this can be extract with RPM?

Read the zypper man page, it seems both the zypper and the info command have some options that might help.
Maybe there's other rpm tools that provide the info you are looking for.

Or maybe your package manager simply does not store that information, at least not directly, per package.

No. RPM database doesn't track repository data. That said, the repo can sometimes be indirectly inferred from fields like DISTRIBUTION, VENDOR, or BUILDHOST, but this is very unreliable and obviously not what you're looking for.

I don't know of any zypper command comparable to apt-cache madison tcsh or repoquery --location tcsh. Or even to

Code:

dnf -q rq --qf '%{repoid}' tcsh

But I don't use openSUSE.

Besides zypper if, zypper se -s should also display repository name. FWIW, zypper can produce parseable XML output with option --xmlout.

Hi, I tried to read the man page. This is why I figured that way above. The zypper info does not have any additional useful commands here:

Code:

zypper info --help
info (if) [options] <name> ...

Show detailed information for specified packages.

  Command options:
-r, --repo <alias|#|URI>  Work only with the specified repository.
-t, --type <type>         Type of package (package, patch, pattern, product).
                          Default: package.
    --requires            Show also requires and prerequires.
    --recommends          Show also recommends.

Zypper repos as well. After looking into man, I opened this question.

I don't have dnf installed. zypper if is just zypper info that I used and there are no additional options. Also, I'm familiar with the xmlout option but it's quite bad:

Code:

zypper --xmlout info gcc
<?xml version='1.0'?>
<stream>
<message type="info">Loading repository data...</message>
<message type="info">Reading installed packages...</message>

Parsing the command without --xmlout is actually easier

Well, if it's SLE you're using, why won't you ask their support?

computersavvy · 07-03-2021, 02:22 PM

Why couldn't you use something like
zypper --xmlout info gcc | grep Repository
to great effect.

shruggy · 07-03-2021, 02:34 PM

@computersavvy. This is what I believe OP currently does (without --xmlout). They asked if there is a better approach.

Not likely what you want, but the repo name and download URI do show up:

Code:
