After upgrading Fedora 33 → 35 via the Software GUI boot fails with message “Oh no! Something has gone wrong.”
Just before it prints “NVIDIA kernel module missing. Falling back on nouveau”
Booting with flag “systemd.unit=emergency.target” directly prints:
/lib/libstdc++.so.6: version `GLIBCXX_3.4.29’ not found (required by /lib64/libproxy.so.1)
Attempting to use dnf or yum results in similar error messages.
Attempting to boot older kernel versions ends in a black screen.
What can I do?
