Thanks for taking the time to report this bug and helping to make Ubuntu better. We appreciate the difficulties you are facing, but this appears to be a "regular" (non-security) bug. I have unmarked it as a security issue since this bug does not show evidence of allowing attackers to cross privilege boundaries nor directly cause loss of data/privacy. Please feel free to report any other bugs you may find.

This looks odd, I checked tidy/libtidy if they would conflict but they work fine:

It seems you installed 18.04 and there was no upgrade to tidy/libtidy since 18.04 was released so I have to wonder why it was updated now according to your logs.

This case is odd, but I can't see the root cause.
If you have any background on what triggered this upgrade and how you got the error I'd appreciate, but from the logs so far I can't take any action.

I checked the supposed owner of the file:
libtidy5: /usr/lib/libtidy.so.5

But then I realized the 5.4 in your bug report.

Thank you for taking the time to report this bug and helping to make Ubuntu better.

Since it seems likely to me that this is a local configuration problem, rather than a bug in Ubuntu, I'm marking this bug as Incomplete.

If indeed this is a local configuration problem, you can find pointers to get help for this sort of problem here: http://www.ubuntu.com/support/community

Or if you believe that this is really a bug, then you may find it helpful to read "How to report bugs effectively" http://www.chiark.greenend.org.uk/~sgtatham/bugs.html. We'd be grateful if you would then provide a more complete description of the problem, explain why you believe this is a bug in Ubuntu rather than a problem specific to your system, and then change the bug status back to New.
