'sudo topgrade' is not working.

i just tried to call topgrade with 'sudoand-y` so that i could run it in the background without intervention, but sudo didn't find the command. Confusingly, running 'sudo su' before running topgrade worked perfectly. I am somewhat new to linux, what did i mess up here?

can you paste the error you see when running with sudo?

I'm not sure if this is in the documentation somewhere, but my understanding is that we should avoid running topgrade as superuser directly. The tool will ask for your superuser password when required. If you want to avoid retyping it do as follows:

topgrade --edit-config

In the configuration file, add or uncomment the following line:

[misc]
    # ...
    pre_sudo = true
    # ...

---

Runing topgrade itself as superuser means running every upgraded tool as superuser - some of which might not be designed to be executed at this privilege level.

The error message i receive is 'sudo: topgrade: command not found'.
Thank you for pointing out the config option, i will be using that instead.

Yeah, you got the cmd not found error because sudo on Linux won't preserve PATH, see https://stackoverflow.com/questions/257616/why-does-sudo-change-the-path

And you should use the pre-sudo config entry.
