@goodthings said in fatal error - cannot restore 2.4.2 backup in 2.4.4:
Unfortunately I don't have portal access.
In an act of pure desperation I searched github for the function "function upgrade_174_to_175()" and found that it relates to ipsec phase1.
The (non-functional) 2.4.2 config looked like this:
<ipsec>
<phase1></phase1>
<logging>
[...]
</logging>
</ipsec>
I compared it to other configs and manually deleted the empty "phase 1" element. The configuration upgraded successfully.
<ipsec>
<logging>
[...]
</logging>
</ipsec>
That was a bit of a nightmare. ☹
Thanks for this bit of information. I was reinstalling from a rather old configuration file and my XML file just had a <phase1 /> line. After removing that the configuration installed properly.
Without removing that my dashboard was extremely slow to load and my NIC assignments would not persist on reboot.
