Hi,
tested on current `stable-2` branch. Seems to work just fine, at least on a clean PBS installation.
Some comments regarding the code are inline (nothing major though).

The `check_pbs_packages` function is a bit long and hard to read, maybe break this
into multiple subroutines? Generally I prefer to have functions that fit entirely on screen without
scrolling, unless there is a good reason against it.

Nit: You could inline the variable here: `format!("{err}")`
Also applies to many other locations in the code, I'll refrain from highlighting the other occurences ;).

You could change the signatures for the `log_*` functions to
pub fn log_pass<T: AsRef<str>>(&mut self, message: T) -> Result<(), Error> {
self.log_line(LogLevel::Pass, message.as_ref())
}
-> then the function can take a `String` as a well as `&str`, allowing you to omit the
`as_str()` calls in various places.

Nit: I'd probably write something like:
let (krunning, kinstalled) = if self.upgraded {
(
Regex::new(...),
"pve-kernel-..."
)
} else {
...
}
That way you can avoid the `mut` and also avoid compiling a regex that is not actually used.

Nit: Also here you could avoid the `mut` and use the `Command` in a chained fashion:
let output = Command::new(..)
.arg(...)
.output();
match output {
...
}

`Path::is_file(&self)` takes `&self` as parameter, so I'd just write:
`if !Path::new("...").is_file() {`

The function below is deeply nested (up to 7 levels, if I counted correctly), maybe break
stuff out into smaller functions?

clippy: You can use `unwrap_or_default` here.
