I'm trying t re-install Ventura on my 2017 imac. Installation proceeds normally until the last 1/8th of the progress bar. It then proceeds very slow. Started out by saying it would take days to install and now <overnight> it says about 4.5 hours remaining.
Is this likely a hard drive issue? It has a 1TB ssd.

Well.. about 2 hours after I posted this question it actually finished the install and I'm in the process of restoring everything else from Time Machine. I'm not sure I'm healthy yet but it is encouraging.
Were you connected to the internet via WiFi or Ethernet? WiFi is known to be unreliable with potential for introducing errors due to momentary dropouts.
If it was WiFi connect with Ethernet for future system updates and upgrades..
Have you installed and run any "cleaning", "optimizing", "speed-up", anti-virus or VPN apps on your Mac?
Was connected via Ethernet... Fairly fast connection. Took almost 15 hours to get the os loaded.
None....
Got about an hour left on the time machine restore.

15 hours is entirely too long. There is something amiss there. The TM migration did take me several hours due to the fact that it was an HDD and the complex ecosystem of hard links in the backups.
Agreed... Once the system is restore I'll run the diagnostics and see if anything shows up. I suppose it could still be a bad ssd.
Time machine has about a 1/2 hour to complete the restore.
Time machine finished the restore... I'll run diagnostics in the morning.
Diagnostics pass with no issues.
Restored and new time machine backup complete.
Let us know if the performance improves or not. 🤞
So far so good....
installing ventura very slow
