Update hangs on Debian

[halt9k]

Describe the bug
Update from GUI from v2.12.7 to v2.13.8 hangs:

• reaches 100%
• asks elevation
• after elevation does not progress out of 100%.

This is reproducible under almost default small Debian ISO installation under VM.

OS and app information:

• OS: Debian GNU/Linux 12, kernel 6.1.0-12-amd64, Xfce 4.18
• App version v2.12.7

To Reproduce

• install default small Debian ISO into VM (with Xfce)
• notice update label, do not press yet
• Turn on VPN
• press update label
• wait 0% to 100%
• allow elevation when asked

Additional context
Have not tested if update ever worked on the previous versions
When updating manually it did not succeed too, one specific package was missing. Installing that package manually allowed v2.13.8 to start. Don't remember the package name though.

Bonus issue:
Way too minor to report separately, default icon colour on the default (?) Xfce is almost invisible in the tray:

Hello,

Thanks for the report. This has already been fixed as of 2.13.6 (meaning if you update FROM 2.13.6 or later, you will not encounter this issue). The missing package was psmisc (which provides 'killall', used in the update script).

As for the icon color, unfortunately as far as we're aware we don't know of any way to detect the tray background color that works for all DEs on Linux. However, you can change the tray icon color manually in Preferences => General.

For the update, can only add keep up the great work (possibly will verify it on the next update)!

For the icon, I had actually ISO nearby and made fresh install just to ensure that Xfce default colour is gray (screenshot above is correct).
Possibly solvable without colour detection: if during install Xfce is detected (and therefore default Windscribe colour is changed to black) - solves this too. At least if Xfce colour is constant with versions (seems so).

Your suggestion for the icons is noted, though we are reluctant to add any kind of DE detection either, due to the massive number of DEs available in Linux. Some of them are also not consistent and flip back and forth between light-on-dark and dark-on-light. We will keep this on the backburner for now, but your feedback is appreciated. As I mentioned previously, you can manually change this in preferences, for now.
