Error while updating Pi Hole

[sunnyqueen]

im getting the error "URL not found" when trying to update (FTL)

[i] Checking for updates...
[i] Pi-hole Core: up to date

[RamSet]

curl (23) stands for

"Write error. Curl couldn't write data to a local filesystem or similar."

Do you have enough space on your device?
What about permissions ?

Could also be due to an error where curl closes the pipe and does not process the rest of the request.

Is it consistent ? Or just a one-off ?

[sunnyqueen]

yes it seems to be consistent, space is also ok I think

tried with sudo pihole -up but didnt made a difference

[RamSet]

@sunnyqueen

sudo pihole -up

you don't have to run it with sudo.
Pi-hole automatically checks for sudo utility and when needed, calls the commands with sudo.

Try running it without the sudo.

[sunnyqueen]

i tried both, same thing happens

[RamSet]

what's the output of pihole -v ?

[sunnyqueen]

im afraid i just fixed it somehow.. dont know on which version i was but im now on

Pi-hole version is v3.3.1-81-g1cae76b (Latest: v3.3.1)
AdminLTE version is v3.2.1-167-gffb75563 (Latest: v3.3)
FTL version is vDev-3656ba2 (Latest: v3.0)

i I tried to reproduce the error by reverting to main and also to development but that did not reproduce it

so fix was to

echo "FTLDNS" | sudo tee /etc/pihole/ftlbranch
pihole checkout core FTLDNS 
pihole checkout web FTLDNS

i tried this (from Help Us Beta Test FTLDNS – Pi-hole ) because i think i remember having enabled that but forgot about it, so idk if it is related because i cannot reproduce the error but at least it fixed it
