ClamTK: Unknown error. Desktop file appears to be are valid.

[michael]

Unknown error. Desktop file appears to be are valid.

michael@michael-Inspiron-531:~$ lsb_release -rd
Description: Ubuntu 20.04 LTS
Release: 20.04

michael@michael-Inspiron-531:~$ apt-cache policy clamtk
clamtk:

I expect ClamTK to tell me, what the error is.

It says, Unknown error. Desktop file appears to be are valid.

Answer from Launchpad.
For several other messages showing "Unknown error. Desktop file appears to be are valid.":
The error message is incomprehensible. I assume that it comes from clamtk and might be reported as bug against clamtk. The message does not tell what clamtk deems wrong, so I cannot judge what okular should change to make the error disappear.

Overall I do not see any severe problem or malware or trojans.

Hi,

Can you give some more information on this? Maybe this is my lack of experience with Ubuntu, but I don't understand what the error is or how it comes about. Does clamtk run?

Thanks,

[michael (yellupcm-gmail)]

I ask question about parsing error, in Launchpad question #691449. Answer was to file a bug. bug #1884815

Will show dialogue, between Launchpad and me.

I was looking through Applications. I saw an icon I didn't know what it did. Menu Editor, clicked on it, this is what came up.

Clicked on details. Got this.

Clicked middle icon on right side. I got a page, that had many different sentences, in different languages. Using Google Translate, most said to do virus scan. Did two scans, first had three Trojans. I deleted them. The second scan is what you see. Later, I clicked Menu Editor again, this is what I got.

My interpretation of what you see:

The "Menu Editor" starts clamtk to check the *.dektop files for wrong entries, and clamtk complains about some configuration settings in these files that it deems not correct.

When you click the middle icon on the right side in the first line (.../clamtk-kde.desktop), you see the contents of that desktop file. It starts with

[Desktop Entry]
Name=clamtk
Exec=clamtk %F
Type=Service
ServiceTypes=KonqPopupMenu/Plugin
MimeType=inode/directory;application/octet-stream;
X-KDE-StartupNotify=true;
Actions=openScanner;

[Desktop Action openScanner]
Icon=clamtk
Exec=clamtk %F
Name=Scan for threats...
Name[af]=Skandeer vir virusse...
Name[ar]=إمسح للكشف عن الفيروسات
Name[ast]=Buscar amenaces...
Name[az]=Təhlükə mövcudluğuna yoxla...
...

Yes, of course you see the text "Scan for viruses" in different languages, because that is the purpose of a *.desktop file - giving a description for an executable program in whatever language you have selected as your desktop language.

According to https://specifications.freedesktop.org/desktop-entry-spec/latest/ar01s06.html the clamkt scanner is right, when it complains about "Type=Service", because the value 'Service' is not valid. This is something that comes from Debian and should probably be reported as bug there.

Thank you for the explanation. Will mark as solved. Will file bug reports.

Hi,

Thank you! I see now. You're talking about this:

"This specification defines 3 types of desktop entries: Application (type 1), Link (type 2) and Directory (type 3). To allow the addition of new types in the future, implementations should ignore desktop entries with an unknown type."

Right? Also, this issue is actually with clamtk-kde, according to your screenshot.

That's an easy fix, if I understand correctly. I'll get a new version out (hopefully) this week.

Thanks,
Dave M

Hi

I just realized why I never changed it to Application - because the context menu won't show up. This would defeat its purpose of scanning files/directories on right-click.

Does anyone know of a way to make this happen if changed to Application?

Thanks,
Dave M
