Raspbian _isn't_ Debian. Wolfram-engine is a third party (commercial) app - Wolfram Mathematica which the Raspberry Pi foundation licences with a special educational arrangement. You might be able to force a reinstall of wolfram-engine to produce something consistent to then remove but this is probably wasted effort. Rather than trying to update from 8 to 9, unless you have significant data invested, I would suggest simply downloading a copy of the latest release of Raspberry Pi OS based on Debian 11. Although I can guarantee that Debian should be upgradable between major releases, I can't be sure for other Debian derivatives. As ever, for Debian: https://wiki.debian.org/DontBreakDebian Debian installers which will install something closer to vanilla Debian are available - but don't include Wolfram's software. They're unofficial in that they're dependnet on non-free software to install. See https://cdimage.debian.org/cdimage/unofficial/raspi/ Quickest solution: install Raspberry Pi OS latest version - available from https://www.raspberrypi.com/software/ With every good wish, as ever, Andy Cater > > I first wanted to upgrade everything which doesn't causes any > > conflicts, which fails because of problems in wolfram-engine: > > wolfram-engine appears not to be a debian package, for starters. > > [snip] > > > Unescaped left brace in regex is deprecated, passed through in regex; > > marked by <-- HERE in m/^(.*?)(\\)?\${ <-- HERE ([^{}]+)}(.*)$/ at > > /usr/share/perl5/Debconf/Question.pm line 72. > > Unescaped left brace in regex is deprecated, passed through in regex; > > marked by <-- HERE in m/\${ <-- HERE ([^}]+)}/ at > > /usr/share/perl5/Debconf/Config.pm line 30. > > Looks bad, but deprecation isn't an error. > > [snip] > > > dpkg: unrecoverable fatal error, aborting: > > files list file for package 'wolfram-engine' contains empty filename > > E: Sub-process /usr/bin/dpkg returned an error code (2) > > Failed to perform requested operation on package.
