Seems to not work with packages that have a dash (-) in the name.. Seems to have been a problem with the cache.. about hoorex HOT 5 CLOSED

I'm not sure why its like that for you. Using the same commands, I see:

Your result is definitely strange - notice the line "Processing initial targets of: []" as if its not seeing the target package name. If you have some time for some extra testing, could you find line 81 in hoorex that says: 'args = parser.parse_args()'; then immediately after that line, add a new line saying 'print(args)'? That will print out whatever hoorex thinks has been passed from the command line. In that case, I see:

Notice that the extra output includes "target=['ttf-mscorefonts']". Does your new output have that?

from hoorex.

Yup, it seems to have that:

Dont know why it is not working with some packages...

Removing .local/share/hoorex/repoData.pkl seems to have fixed the issue.

hoorex 

from hoorex.

Interesting. After removing the repoData.pkl file, a new one would be generated when you run the next hoorex command. Since it now works OK, the old one must have been faulty/corrupted somehow.

BTW when you say you removed the .local/share/hoorex/repoData.pkl, I assume you meant ~/.local/hoorex/share/repoData.pkl did you i.e. relative to the user's home directory?

from hoorex.

Yes on both counts, a new one was generated, and I meant relative to home directory.
