Exelent!
Tested the code from github. 'Package System Repair' is working.
I think it's ready. Shall we wait unti LL 2.4 beta to anounce or you want to update it now?

[valtam]

I'll create an updated package soon for release. Thank you for helping :)

[anon222]

Glad to help. :)
So, you are preparing the new release?
What happened to Lite Control Center? Will it be ready for LL 2.4?

[valtam]

So, you are preparing the new release?

Yes, I will do that tonight.

What happened to Lite Control Center? Will it be ready for LL 2.4?

We have a python3 version but I am unable to verify that it works due to the fact it was developed with the latest versions of some software.
I'm still waiting on the python2 version from the devs working on the Bounty. To be honest it doesn't worry me that much as with such an awesome piece of software, it would be nice to make it the main event in LL 3.0 :)

[anon222]

So it's going to be named LL 3.0 after all :)
The community has decided on numbering system.
It's fine if you ask me. Still better than the Windows system (1,2,3,95,98,Me,2000,XP,Vista,7,8,10)
:D

[valtam]

Yup, the power of community :)

[valtam]

Just thought, because there will be future versions of LL, eg. 2.4, 2.6 and 2.8 we'll need to somehow ensure that with 'Bootup Fix' we'll have to add a check or change the sed command according to the version of LL it's fixing. Perhaps by checking /etc/llver ?

I know. From 2.0 to 2.8. I think lite-tweaks-super should handle that. For every release the commands should be different.

[anon222]

I don't know what colors releses use. Are they the same for all 2.X?
Now lite-tweaks-super checks for LL version
also I've hidden the option to remove residual config files. I guess that way there will be no error when there are no residual config files to remove.
