I prefer to not use Google Authenticator, but to use a different program instead, like Aegis Authenticator. Unfortunately, it apparently only runs on Android.

For what you are ultimately trying to accomplish, I think that a better solution would probably be to use a program like numberstation or Gnome Authenticator.

The problem of files mysteriously disappearing is still an issue since I recently had another one disappear. I was beginning to wonder if the HDD is going bad, so yesterday I analyzed it using smartctl. Other than some occasional ICRC errors, the drive appears to be healthy. The ICRC errors suggest that the SATA cable may be bad or loose, though, so I am going to replace it soon.

Unreliable electrical power is a problem where I currently live. There are frequent, short power failures here, especially during storms and on windy days. Could this be causing my documents to disappear? Although power failures can cause data loss, I doubt that this is the cause because the files were not being written to when the power failures occurred. In fact, I don't think the files were even open. So, unless I am wrong about this, it seems that the cause of my disappearing documents is still a mystery.

Take a look at this:

Package: bilibop-lockfs
https://packages.debian.org/stable/bilibop-lockfs

It's intended to be used for external media, but can probably be used for internal drives as well.

There is also uBlock Origin Lite which does work in Edge and the newer versions of Chrome/Chromium.

When I have some time, I will attempt to build an installer ISO. Not quite eight years ago, I built several live CDs. Maybe what I learned from those experiences will be helpful.

This website is likely to be very useful: https://snapshot.debian.org/

It appears that some very recent packages can be found here:

You may be in luck. I stumbled upon this yesterday and saved the info because it looks like it could be very useful:

Thanks for the tip.

Live streaming seems problematic to me if the sessions are announced in advance publicly since this lets potential adversaries know when to carry out their attacks (or attempted attacks). If possible, coordination should be carried out using encrypted chat (including encrypted voice calls), rather than using insecure communication methods like email, public websites, regular telephone calls, and SMS text messages.

An idea just came to me, so I went ahead and tried it:

$ aptitude why libc++1-16
i   atril                Depends libatrilview3 (= 1.24.0-1+deb11u1)
i A libatrilview3        Depends libwebkit2gtk-4.0-37 (>= 2.5.3)   
p A libwebkit2gtk-4.0-37 Depends libc++1-16 (>= 1:16.0.6)          

$ aptitude why libc++abi1-16
i   atril                Depends libatrilview3 (= 1.24.0-1+deb11u1)
i A libatrilview3        Depends libwebkit2gtk-4.0-37 (>= 2.5.3)   
p A libwebkit2gtk-4.0-37 Depends libc++abi1-16 (>= 1:16.0.6)       

$ aptitude why libunwind-16
i   atril                Depends libatrilview3 (= 1.24.0-1+deb11u1)
i A libatrilview3        Depends libwebkit2gtk-4.0-37 (>= 2.5.3)   
p A libwebkit2gtk-4.0-37 Depends libunwind-16 (>= 1:16.0.6)

So, apparently the new packages are dependencies of libwebkit2gtk-4.0-37. That's a new one for me. I did not know that packages could suddenly acquire new dependencies. Perhaps this is just one of the oddities that can show up when one is running oldstable.

If you are indeed using Excalibur, then this may be a good example of why many people choose to run unstable (Ceres) instead of testing. Either that, or they run a mixed testing/unstable system -- testing with some packages pulled (as needed) from unstable. The latter approach is the one I would probably use if I were inclined to run a "rolling" system, but didn't want to switch to a totally different distro (e.g., Arch Linux).
