Left over kernel files?

As to the latter, yes. As to the former, it is my belief that this is so; I can't with 100% assurance so it is so.

As a retired programmer who documented his own code (most of the time) I can say that once documentation is written it isn't always updated to reflect recent changes in code. Too busy, too tired, absent minded ... lot's of good excuses.

dequire. I want to thank you for the advice on ucaresystem-core.

I had been getting three warnings/failures on kernel header files, in the last 36 hours. I ran autoremove and purge without effecting the errors when I ran update and dist-config.

ucaresystem-core found 1.3 Gb (as in Giga) files to be cleaned. It took about 15 minutes on my 32 bit system, but IT FIXED THE PROBLEMS!!!!!

Thank you!

You are probably right. Yesterday I noticed an entry in my menu system about chromium, a browser I purged months ago as part of my dump Google activity. I did a locate for chromium and while the binary was not present the entries in .cache and .config were. Ucaresystem-core missed them as well. I manually deleted them.

As far as I can tell, there's no "simulate" option for the program which makes it dangerous in my opinion.

Not having a --simulate option is not good IMO; I would want it. Absent that, then requiring user input: Yes, No; to each sections identified results would be desireable. I know that the script 'as written' is designed to not require user input, but I just don't like anything 'automatically and without my explicit permission' removing stuff from my system.

It is a script, so one could modify it to include these 'missing' options.

[dequire]

I can agree on principal a 'simulate' option would be optimal, however I can attest (and the script clearly dictates) that the commands run are pretty innocuous. When I run 'sudo apt full-upgrade' I never simulate it first, which to me would seem unnecessary. As I said earlier, I've run this program literally hundreds of times and have never been left wishing for that option. However, on principal alone, I could see your point. Since I use the program so much, I'll file the suggestion with the author.

Would have been interesting, as an exercise in system management, if running Bleachbit (as root) would have found and removed those config files.

and maybe you're right, it might not be needed.

Might not even be possible given all the commands it runs. I should report the "Steam" error I experienced, but I doubt I could replicate it.

Maybe an "attended" option that inserts y/n prompts in between each stage?

It's invaluable to me when doing an update AFTER a re-boot from upgrading to a new release and making sure my sources are updated to reflect the new version. Pretty impressive how much leftover stuff I find. I use it so much, I don't bother with 'apt update && apt full-upgrade' anymore. oshunluvr's issue aside, I find it invaluable and am grateful for the author making it.

I am planning to use this. Do I need simply run the script? Or is there one with a graphical user interface? Any precaution steps?
Thanks

[oshunluvr]

No GUI, just run it from the terminal. No options either. Just launch and hold your breath!

Installed uCareSystem Core v3.0 on my HP laptop (it isn't my "primary" PC anymore so I'm not worried if unintended consequences ensue).

I had to run the script five or six times before it no longer identified any 'unused config files'. So deborphan -n --find-config doesn't seem to find everything the first time through. I say that because no additional packages were purged during each of the subsequent runs of this script. But the script does work, and my HP still boots.

There is not much to ucaresystem-core. It is just an executable bash script. All the commands I've marked in red.

The only place I'd change the code is where it purges old kernels. I'd put that command inside the IF test.

#!/usr/bin/env bash
