Need help interpreting boot-repair data

[kalpana]

Please see https://pastebin.ubuntu.com/p/mxPwdgPdmd/

This is an older PC that ran well on Ubuntu until I did the upgrade to 23.04. CPU is x86 Family 16 Model 5 Stepping 3 AuthenticAMD ~3199 MHz.

I am not sure on next steps to take.

Thank you,

John
