[Touch-packages] [Bug 1835957] Re: cupsd gobbles up resources
A week after the downgrade, I did an "apt update" and "apt upgrade" and I think was also upgraded. Since then, has seemed satisfied with resources under 1%, so my impression is that my problem is solved. However, I have no idea what is going on with this bug (that I reported). The status here remains "incomplete", the importance is still "undecided" and the bug is "unassigned". It is as if the bug had somehow solved itself. Or is the status still "incomplete" due to a fault of mine?

[Touch-packages] [Bug 1835957] Re: cupsd gobbles up resources
OK, I did the downgrade again, without the -dev packages. There was no error message this time about "libscupsfilters". But there still is a sticky message on my screen's menu bar that goes like "An error occurred, please run Package Manager or apt-get in a terminal..." Then:"Error: BrokenCount>0". Yes, I have a Samsung Unified Driver installed – since several years. That is, it has been in use well before the current resources problem surfaced. Meanwhile, the downgraded seems to be running pretty quietly.

Oh yes, I forgot to report what is perhaps the most important point, namely, that the downgrade seems to have solved the resource issue. But, well, I'm not 100% sure, yet. I wrote earlier that one instance of printing made the problem go away, but then, the next time I tried this, it didn't (go away).
