Comment # 6 on bug 1190267 from Michael Andres

Thanks. The rotated log covers the install date mentioned in the history.

The log mentions a solver testcase has been written to 
   /var/log/updateTestcase-2021-09-07-18-42-16

Please pack the directory if it still exists and attach it to the bugreport:

> $ cd /tmp
> $ tar cvjf zypper.updateTestCase.tar.bz2 /var/log/updateTestcase-2021-09-07-18-42-16

In case the testcase exceeds the 10MB limit for bugzilla uploads, you can use
'split' to divide the file into smaller pieces:

> $ split -b 10M --additional-suffix=-zypper.updateTestCase.tar.bz2  zypper.updateTestCase.tar.bz2
>
> The created pieces will be named like this:
> xaa-zypper.updateTestCase.tar.bz2
> xab-zypper.updateTestCase.tar.bz2
> xac-zypper.updateTestCase.tar.bz2
> ...
