@movq@www.uninformativ.de Yes, Alexander Batischev tries to keep the Rust version bumps fairly moderate with Newsboat: https://github.com/newsboat/newsboat/issues/709
I was actually positively surprised that after the outlined rustup upgrade oneliner above, running make in Newsboat again worked flawlessly. Nothing else required. I delayed rebuilding for quite some time because I thought getting this Rust toolchain sorted out is going to be a major endeavor. Luckily, I was wrong. :-)
I just don’t know if I now have two Rust installations in parallel or not. Or how much disk space I waste with all this. At least the script didn’t tell me it found an old installation. It printed heaps of stuff, but skimming over it, I didn’t see anything like that. I then simply selected the regular install. Whatever that meant. Researching this topic will be a project for another day if I’m really bored.
