pacman -Sy succeeded but no files are installed

I executed `sudo pacman -Sy certbot` to install `certbot`.

After the installation, executing the `certbot` command gives the following error:
```
Traceback (most recent call last):
  File "/usr/bin/certbot", line 5, in <module>
    from certbot.main import main
ModuleNotFoundError: No module named 'certbot'
```

To check which files are installed by the package, I executed `sudo pacman -Fl certbot`:
```
(snip)
certbot usr/bin/certbot
certbot usr/lib/
certbot usr/lib/python3.8/
certbot usr/lib/python3.8/site-packages/
(snip)
certbot usr/lib/python3.8/site-packages/certbot/__init__.py
(snip)
```

However, `ls /usr/lib/python3.8/site-packages/certbot/` gives the following error:
```
"/usr/lib/python3.8/site-packages/certbot/": No such file or directory (os error 2)
```

Is this a bug of `pacman`?

Re: pacman -Sy succeeded but no files are installed

Try -Syu instead of -Sy.

Others will no doubt be along soon to give you the "partial upgrades are not supported" lecture

Re: pacman -Sy succeeded but no files are installed

Partial upgrades are only a part of the problem: it looks like* you haven't updated in well over three years!

You should really install a distro more suited to your use.

edit: *looks can be deceiving.  Perhaps just your files database is ancient.

Re: pacman -Sy succeeded but no files are installed

don't run pacman -Sy (also not -Syuw; -Sy packagename); it will probably give you non-updated dependency issues, especially if you haven't updated in 3 years.

EDIT: thought i read -Syu packagename somewhere, nevermind.

always run pacman -Syu and then run pacman -S packagename

Wouldn't pacman -Syu packagename just add a package to the list of packages that gets updated through -Syu?

That would also imply a really old version of Linux kernel :/

Re: pacman -Sy succeeded but no files are installed

As hinted at by seth, it's more likely their file database is simply out of date. As already mentioned, use -Syu certbot to fully update the system and installc certbot, partial upgrades are not supported: https://wiki.archlinux.org/title/System … nsupported

Unless you can explain in detail, why you think -Syu packagename is problematic, I call FUD.

Re: pacman -Sy succeeded but no files are installed

"-Syuw" isn't inherently wrong either - you're just preparing to actually update later on and priming the cache this way.
You just need to be aware that you did this, so the next call shall not be "-S foo" but "-Su" (or "-Su foo")

While technically you're setting yourself up for a partial update, this call at least has legitimacy, eg. if you've inconsistent internet access and "time slot online" != "time slot ready for update" and is most likely "intentionally cause I know waht I'm doing"
