I've found that there is a maintainer who publishes SimAVR for Ubuntu here:
https://packages.ubuntu.com/bionic/simavr
Seems to be kept reasonably up-to-date (the latest there is 1.15 whereasy here on GitHub it is 1.16).
I know that maintainers do not always keep in contact with the software vendor so I would not be surprised to learn you were not aware of this. If you are okay with it though and consider it to be a legit enough source, I figure it's good to call that out in the README.

Fix timer1 on tinyx5
The prescaler list for timer1 on the tinyx5 was incomplete. Moreover,

Setting a default wgm_op makes time timer run in normal mode witha size
of 8 bits.

Fix receiving after fifo overrun
After fifo overrun buffer_done remains less than buffer_len and
FD_SET(p->port[ti].s, &read_set) is not called. If firmware has nothing
to send, select always returns 0 and new data is never read even if
fifo buffer gets flushed.
This patch removes check for select timeout, so the remaining data in
buffer may go to fifo.

Correct x8 ADC mux modes
In all of the datasheets for ATmega44/88/168/328 devices that I've
seen, there are 8 channels of ADC selected with MUX modes 0000-0111,
and the temperature sensor is selected with MUX mode 1000.
modify avr_callback_sleep_raw() to mitigate sim time and wall clock time divergence
To avoid simulated time and wall clock time to diverge over time
this implementation tries to keep them in sync (roughly) by sleeping
for the time required to match the expected sleep deadline
in wall clock time.
The simulation will burst as fast as the host CPU will allow
until the simulated MCU sleeps, at which point avr_callback_sleep_raw()
sleeps for the time required to sync wall clock time with simulated MCU
time.
Fix a bug which causes no cores to be compiled
On some systems, including some Mac and some Linux computers, the

that it works perfectly on Mac.

ssd1306: move display vertical and horizontal mirroring to OpenGL scene setup
The idea is that the display orientation related code belongs in the
board's implementation. Prior to this commit boards which mount the
display with a different orientation would end up mirroring the pixels
twice: once when reading them from the framebuffer and again in the
OpenGL scene rendering. As a sideeffect now reading pixels from the
vram array is simplified.

Added a define "FALLTHROUGH" to suppress 'this statement may fallthrough' messages
Since avr-gcc version 7 the flag -Wimplicit-fallthrough is set, so that
a missing "break;" inside a switch-case statement will throw an error in
the compiling process.
The missing breaks are replaced by the FALLTHROUGH define and no errors
occours.
FALLTHROUGH is simply an "__attribute__((fallthrough));" - if it is
supported by the compiler.

parts: Build a simavr virtual parts library
An external project using simavr can link against libsimavr.
However, there is no support for using virtual parts from the
examples folder in the external project.
This commit adds support for building a parts library, which the
external project can link against. Presently this library is fairly
small, but as the number of parts grows this approach may need
to be changed. A longer term solution could be to provide an API as
part of the simavr library which can manage the parts. Simavr could
dynamically load and provide parts as required by the external
project.
Like libsimavr, this patch makes no attempt to make the version easy
to set. That can be covered under a different PR.
