Tor Browser Launcher from sid is at present uninstallable.
I pulled latest Tor browser from the website.

Seems the QT dependancy problem has been around on and off for years.
The offending library is a virtual package within libqt5core5a.

Below quick and effective dirty hack found on a KDE Neon page and
updated, it gets things working, up to now I see no untoward effects.
That is not a garantee. :-)…
Users should keep a copy of changes made just in case it is needed later.
Easy to remove any packages as long as console access is available. AND
you know what to remove.
That is generaly applicable.

Better fix needed upstream, this is more an easily reverted workaround.
This time I have not posted a bug report, last one left me with an
unusable EMail account to to massive spam. EMail is openly displayed
with the bug report.

Hi Moddit,

Although I am not currently using the Tor browser, knowing the problem and the fix is something I will make note of.

Thanks.

To clarify, as i already noted, TorBrowser bundle from Tor website works fine.

The issue affected torbrowser-launcher, a debian application which is intended
to make installation of torbrowser easier.

We have very troubled times well knowing tor will be watched by interested services,
cia nsa ghcq etc it may still help some to save their ass in countrys like Ru or Iran.

Note: I have seen the issue reported as affecting other applications, the script to
create a dummy package which I modified came from old posts regarding KDE Neon.

Please beware if you are a Sid user; there is yet another qtbase-abi issue in Sid; for me, it broke sddm and I had to resort to either re-enabling lightdm to start my X server display or use startx. Sddm is broken because of this, and so is anything else that has dependencies on qtbase-abi.
