OpenSUSE 16.0 builds do not work on SLES 16.0

[gaborcsardi]

First, x.org is missing from SLES, apparently:

Enter version to install: (<ENTER> for latest)
4.5.2
Installer already exists. Not downloading.
User install from RPM installer R-4.5.2-1-1.aarch64.rpm...
Updating package indexes...
Refreshing service 'container-suseconnect-zypp'.
Repository 'SLE_BCI' is up to date.
All repositories have been refreshed.
Installing R-4.5.2-1-1.aarch64.rpm...
Refreshing service 'container-suseconnect-zypp'.
Loading repository data...
Reading installed packages...
Resolving package dependencies...

Problem: 1: nothing provides 'xorg-x11' needed by the to be installed R-4.5.2-1-1.aarch64
 Solution 1: do not install R-4.5.2-1-1.aarch64
 Solution 2: break R-4.5.2-1-1.aarch64 by ignoring some of its dependencies

Choose from above solutions by number or cancel [1/2/c/d/?] (c): 2

Ignoring the dependency:

> x11()
Error in x11() : X11 module cannot be loaded
In addition: Warning message:
In grSoftVersion() :
  unable to load shared object '/opt/R/4.5.2/lib/R/modules//R_X11.so':
  libSM.so.6: cannot open shared object file: No such file or directory

Adding the oss opensuse 16.0 repo fixes this:

zypper addrepo http://cdn.opensuse.org/distribution/leap/16.0/repo/oss/aarch64 repo-oss
zypper refresh

This needs a manual step to accept the signing key, this can be probably automated:

76ebfcbb3cd8:~ # zypper refresh
Refreshing service 'container-suseconnect-zypp'.
Repository 'SLE_BCI' is up to date.
Looking for gpg keys in repository repo-oss.
  gpgkey=http://cdn.opensuse.org/distribution/leap/16.0/repo/oss/aarch64/repodata/repomd.xml.key

New repository or package signing key received:

  Repository:       repo-oss
  Key Fingerprint:  AD48 5664 E901 B867 051A B15F 35A2 F86E 29B7 00A4
  Key Name:         openSUSE Project Signing Key <opensuse@opensuse.org>
  Key Algorithm:    RSA 4096
  Key Created:      Mon Jun 20 14:03:14 2022

    Note: Signing data enables the recipient to verify that no modifications occurred after the data
    were signed. Accepting data with no, wrong or unknown signature can lead to a corrupted system
    and in extreme cases even to a system compromise.

    Note: A GPG pubkey is clearly identified by its fingerprint. Do not rely on the key's name. If
    you are not sure whether the presented key is authentic, ask the repository provider or check
    their web site. Many providers maintain a web page showing the fingerprints of the GPG keys they
    are using.

Do you want to reject the key, trust temporarily, or trust always? [r/t/a/?] (r): a

IDK if adding this repo would be reasonable for SLES 16.0 users. Do we know anyone that uses our builds on this distro or on other SLES versions?

EDIT: adding the oss key is easy:

rpm --import https://cdn.opensuse.org/distribution/leap/16.0/repo/oss/aarch64/repodata/repomd.xml.key

If adding the OSS repo is reasonable, then we could add some instructions to the README.

The same happens for SLES 15.6 as well, possibly also for older versions. The URL for 15.6 is different:
