Strange upgrade questions

English Install/Boot/Login

On a 15.5 machine, I try to make a zypper dup and I receive messages such as this one:

780 packages to upgrade, 8 new, 1 to remove.
Overall download size: 1,11 GiB. Already cached: 0 B. After the operation, additional 283,1 MiB will
be used.

    Note: System reboot required.

Accepting packages with wrong checksums can lead to a corrupted system and in extreme cases even to a system compromise.

However if you made certain that the file with checksum '6846..' is secure, correct

Why do packages from SLE 15.4 appear? (I would expect packages from SLE 15.5 or from Leap 15.5)
What should I do? Go for 6846 and go on the same way with the other packages, for example:

Do not use “zypper dup” on Leap unless you want to a “distribution update”, use “zypper up” instead.

3

You should start with showing you configured repositories

zypper lr -d
4

Going from any pre-release to release is distribution upgrade.

zypper lr -d

This is repository issue which has nothing to do with Leap 15.5. Repository metadata does not match the actual package. Looking at packages

bor@bor-Latitude-E5450:~/tmp$ curl -LI http://ciscobinary.openh264.org/libopenh264-7-2.3.1-2.sle150400.1.x86_64.rpm
HTTP/1.1 200 OK
Last-Modified: Wed, 24 May 2023 20:42:59 GMT

while timestamp on codecs.opensuse.org is

23-May-2023 15:20

It is not timezone issue because minutes do not match. So it looks like Cisco updated their binaries and this change was not propagated to openSUSE repository.

I have no idea where to report it to be honest. You probably can try contacting maintainers mentioned on OpenH264 - openSUSE Wiki, mail to Factory list may be appropriate too.

Because that is what OpenH264 repository has. Whether these packages are also suitable for Leap 15.5 I do not know (they well could be, after all some binaries installed on openSUSE are built on SLE 15 GA and they work). You could try asking the same persons and post your findings here.

Thanks for the answers.
At the end, I just tried to unblock the checksum of the packages in questions. 3 packages seemed to be affected and the rest was OK.
The upgraded seems to have been executed without any other problem. Also I guess it will be OK.
