snap pt_BR locale shows warning every time

Status changed to 'Confirmed' because the bug affects multiple users.

It also affects Ubuntu 20.04 LTS after a recent update.

This bug also prevents the use of snap command autocomplete, echoing these error messages when TAB is pressed....

```
$ snap [TAB]2021/08/26 11:39:40.041113 main.go:176: description of prepare-image's "<target-dir>" is lowercase in locale "pt_BR": "o directório de destino"

```

I found that there is a typo in the file "/usr/share/locale-langpack/pt/LC_MESSAGES/snappy.mo".

```
$ dpkg -S /usr/share/locale-langpack/pt/LC_MESSAGES/snappy.mo
language-pack-pt-base: /usr/share/locale-langpack/pt/LC_MESSAGES/snappy.mo
$ dpkg -l language-pack-pt-base
ii language-pack-pt-base 1:20.04+20210802 all translations for language Portuguese
```

An available workaround is to fix the file manually...

```
sudo sed -i 's/o directório de destino/O directório de destino/' /usr/share/locale-langpack/pt/LC_MESSAGES/snappy.mo
```

Probably must be fixed into language-pack-pt-base translation sources.

Or.... this can be interpreted as a bug in snapd that imposes capitalization rules on translations, at some "main.go" at line 176, as the message says.
I've downloaded snapd sources and found this validation on "cmd/snap/main.go":

```
$ dpkg -l snapd
ii snapd 2.49.2+20.04 amd64 Daemon and tooling that enable snap packages
$ cd /tmp && apt source snapd
$ sed '174,177!d' /tmp/snapd-2.49.2+20.04/cmd/snap/main.go
                // note IsLower != !IsUpper for runes with no upper/lower.
                if unicode.IsLower(r) && !strings.HasPrefix(desc, "login.ubuntu.com") && !strings.HasPrefix(desc, cmdName) {
                        noticef("description of %s's %q is lowercase: %q", cmdName, optName, desc)
                }
```

$ sudo apt install libgtk3-nocsd0

May be a workround..... Works for me!
on Ubuntu 20.04.3

Regards

I've made a fresh install with Ubuntu 20.04.3 and I'm facing this problem too.
But I think the workaround proposed by Carlos would be a little bit harsh to put in practice since I don't now how many instances of translation are triggering this same error.
Every time I run a snap command, and not just on auto-completion, I receive lots of error messages.
See:

What is your output of "apt-cache policy snapd" and what version of snapd is shown by "snap list"?

I checked their GitHub page, and at <https://github.com/snapcore/snapd/blob/master/cmd/snap/main.go#L173> the description is different from comment #4 since it also includes "in locale "pt_BR"", which itself was changed fairly recently on May 18, 2021 with the commit <https://github.com/snapcore/snapd/commit/d6002db1fbf048baeac4c2e55c2d939579709249#diff-3e3ed6fb2507f825b010f93a1e81f1610fca76413b0eb9588f8c23e7095cf0a2>

The conditional expression itself didn't change though, so I think the bug itself should be before that or was created after it in the translation sources (I don't know how/where to check them though, any help is greatly appreciated)

@kmiksi, actually, I think that your proposed workaround enhanced the problem. The error messages from my previous post started to show up after I've run the sed command you've proposed and I think this happened because the file `snappy.mo` is a binary not an ascii text file. I have reverted my changes by running:

```
sudo apt --reinstall install language-pack-pt-base
```

And now I have only the original error message:

```
$ snap --help
2021/09/16 21:43:52.882927 main.go:176: description of prepare-image's "<target-dir>" is lowercase in locale "pt_BR": "o directório de destino"
O comando snap permite instalar, configurar, atualizar e remover snaps.
...

```

@jrom, @kmiksi may be using Ubuntu 20.04 like me because his version of snapd in apt package is the same as mine:

```
$ apt policy snapd
snapd:
  Instalado: 2.49.2+20.04
  Candidato: 2.49.2+20.04

```
$ snap list | grep snapd

snapd 2.51.4 12883 latest/stable canonical* snapd

```

@jrom, the condition didn't changed. This commit you pointed was released in snapd version 2.51
You can see it here:
https://github.com/snapcore/snapd/compare/2.50.1...2.51

If you compare the release 2.51 with the latest release 2.52:
https://github.com/snapcore/snapd/compare/2.51...2.52

...you will see that there is no significant change in this `cmd/snap/main.go` file. They just changed some lines positions but the content is the same.

The fact that the locale "pt_BR" is not on the code, means nothing since this is replaced in runtime in the variable "%q".

The bug may be in the translation in the `language-pack-pt-base` package itself.

We also have a change in snapd source code that will no longer show these messages: https://github.com/snapcore/snapd/pull/10756

@iogui, every system I've tried works well with that workaround (4 installations with Ubuntu 20.04). Please reinstall language-pack-pt-base an try again.

Yes, it is a binary file, a gettext .po compiled into a .mo. The sed is a quick workaround that works fine for me even with the binary. If you continue having problems, another way is retranslating with these commands:
```
sudo cp /usr/share/locale-langpack/pt/LC_MESSAGES/snappy.mo /usr/share/locale-langpack/pt/LC_MESSAGES/snappy.mo~
msgunfmt /usr/share/locale-langpack/pt/LC_MESSAGES/snappy.mo > /tmp/snappy.po
sed -i 's/o directório de destino/O directório de destino/' /tmp/snappy.po # or edit with PoEditor
sudo msgfmt /tmp/snappy.po -o /usr/share/locale-langpack/pt/LC_MESSAGES/snappy.mo
```

I can't find the origin of these translations to contribute to language-pack-pt-base.
Do you know about these translations and how to contribute?
I only find some git hooks in the sources manipulating translation contents, but don't understood clearly how it is done. Some help is welcome.

The message should no longer be shown anymore in snapd as the PR referenced by Maciej has been merged and should be available on the edge channel of snapd in the few hours. Please give it a try if you like with:

```
snap install snapd --edge || snap refresh snapd --edge

# test the snap command to make sure the message no longer appears

snap refresh snapd --stable
# to go back to tracking stable, as edge sometimes can have unstable changes on it
```

Thanks,
Ian

@maciek-borzecki, good work!! It seems like a good solution!

@kmiksi, I was searching for it too. I don't know how the translations are in fact included in the sources but I've found how we can contribute to the translation, see those links:

@anonymouse67, I've tried the commands you've provided but it didn't work. See:

```
$ sudo snap install snapd --edge || sudo snap refresh snapd --edge
[sudo] senha para my-user:
2021/09/18 12:54:59.334587 main.go:176: description of prepare-image's "<target-dir>" is lowercase in locale "pt_BR": "o directório de destino"
snap "snapd" já está instalado, consulte 'snap help refresh'
```

@iogui could you try again? snapd on the edge channel may not have finished building by the time you tried, but I see that there was an update pushed out this morning.

@anonymouse67, tested just now and the result is the same. I don't know much about snap commands but maybe the parameter "--edge" is not working as you expect it to... shouldn't the command be with a parameter "--channel=latest/edge" to select the channel?... Because I don't know, I've not tried something different as I'm afraid to mess with my system.

@iogui, hmm it could be that our fix isn't working, can you show the output of these commands:

snap version
snap list

Hi (or Olá for the PT crowd). I think snapd just wasn't refreshed, @iogui's output doesn't show it:

```
$ sudo snap install snapd --edge || sudo snap refresh snapd --edge
[sudo] senha para my-user:
2021/09/18 12:54:59.334587 main.go:176: description of prepare-image's "<target-dir>" is lowercase in locale "pt_BR": "o directório de destino"
snap "snapd" já está instalado, consulte 'snap help refresh'
```

`snap install <snap>` (when run on an already installed snap) returns 0. So the right-side of the `||` didn't run and snapd wasn't refreshed to edge.

@iogui, can you run `sudo snap refresh snapd --edge` and let us know if `snap list` logs the warning? I've just tested with edge and the fix seems to be working. If you still see the warning, then could you please run `snap version` and post the output? Thanks for your help

Ah Miguel, thanks for realizing my error, I should have probably just said something like

sudo snap install snapd --edge; sudo snap refresh snapd --edge

which will ensure that it's always installed and gets refreshed.

@anonymouse67 and @miguelpires1, sorry for the delay, I was not at the office today.

@miguelpires1, you're right a simple `sudo snap refresh snapd --edge` did it.

@anonymouse67, the correction seems to work:
