Public bug reported:

uninstallPackage() can fail to return and none of the code after it will
be run. Perhaps there is an error that happens that is not reported by
Mudlet anywhere.  The following code, which accounts for this error:

function svo_doupdate_click()
  svo.updatelabel:echo([[<p align="center" style="font-size:10pt; color:white">Updating Svo...<p>]])
  svo.doupdatelabel:hide()
  svo.dontupdatelabel:hide()

  local name = svo.me.name

  if not (uninstallPackage and installPackage) then
    svo.updatelabel:echo([[<p align="center" style="font-size:10pt; color:white">Can't update your Svo. You didn't update to Mudlet 2.1, and your current Mudlet lacks the features necessary. Go update first please.<p>]])
    return
  end

  if not io.exists(getMudletHomeDir().."/svo/downloads/"..string.format("%s svo.zip", svo.me.name)) then
    svo.updatelabel:echo([[<p align="center" style="font-size:10pt; color:white">Hm, can't update Svo - seems the new system we downloaded dissapeared. Do 'vupdate force' to download it again.<p>]])
    return
  end

  function svo_update_system()
    svo_updating_system = "uninstalling"
    uninstallPackage(name.." svo")

    svo_updating_system = "installing"
    svo.updatelabel:echo([[<p align="center" style="font-size:10pt; color:white">Uninstalled the old Svo, installing the new one now...<p>]])
    installPackage(getMudletHomeDir().."/svo/downloads/"..string.format("%s svo.zip", svo.me.name))

    svo_updating_system = nil
    svo.echof("Svo updated! Restart Mudlet, and you'll be all done. You can find the changelog on svo.vadisystems.com.")

    svo.updatelabel:echo([[<p align="center" style="font-size:10pt; color:white">Svo updated!<br><br>Restart Mudlet, and you'll be all done.<p>]])
    svo.updatelabel:setStyleSheet([[

      qproperty-wordWrap: true;
      font-family: 'Ubuntu','Calibri',serif;
    ]])
  end

  svo_updating_system = "started"
  tempTimer(10, function()
    if not svo_updating_system then return end

    if svo_updating_system == "uninstalling" then
      svo.updatelabel:echo([[<p align="center" style="font-size:8pt; color:white">Hm, seems the update got stuck on the uninstallPackage() function. Try uninstalling Svo from the Package Manager and then installing it from the zip (found in ]].. getMudletHomeDir().."/svo/downloads/"..string.format("%s svo.zip", svo.me.name) ..[[) to upgrade now.<p>]])
    elseif svo_updating_system == "installing" then
      svo.updatelabel:echo([[<p align="center" style="font-size:8pt; color:white">Hm, seems the update got stuck on the installPackage() function.

    end
  end)
  svo_update_system()
end

still has issues that people experience:

Also this is the issue - Hm, seems the update got stuck on the uninstallPackage()function.
 Try uninstalling Svo from the package manager and then reinstalling it from the zip (found in 
C:blahblah) to upgrade now.
