I believe my zapper is now back in service after upgrading to
new hardware multiple times.

1st hardware upgrade attempt MeerKat from system76
USB would loose power after 24 hours of run-time.
Only discovered after completing a full migration.
Return the hardware after retreating to old hardware.

2nd hardware upgrade attempt desktop from Velocity Micro
Issue with graphic card.
returned next day after receiving

Current hardware upgrade desktop from system76
Did a one week burn-in before doing any migrations.
no issues so far.

Now three months or so later, I've updated the local instance
of albyhub and opened a new LSP channel with Olympus by Zeus.

Here is the ablyhub upgrade process that worked for me.

Download current release and manifest files

Navigate to https://github.com/getAlby/hub/releases

Download albyhub-Server-Linux-x86_64.tar.bz2
manifest.txt
manifext.txt.asc
-------------------------------------------------------------

Copy the downloaded files to $HOME

mv $HOME/Downloads/albyhub-Server-Linux-x86_64.tar.bz2 $HOME
mv $HOME/Downloads/manifest.txt $HOME
mv $HOME/Downloads/manifest.txt.asc $HOME
---------------------------------------------------------------

Verify manifest signature & Checksum

Only need to import once

curl https://raw.githubusercontent.com/getalby/hub/master/scripts/keys/rolznz.asc | gpg --import

gpg --verify manifest.txt.asc manifest.txt

shasum -a 256 albyhub-Server-Linux-x86_64.tar.bz2

The above checksum should be referenced in the file, manifest.txt.

cat manifest.txt
----------------------------------------------------------------

Stop AlbyHub & Backup existing data

systemctl stop albyhub

cp -r $HOME/.local/share/albyhub /media/veracrypt1/albyhub
cp $HOME/bin/albyhub $HOME/bin/albyhub114
cp -r $HOME/lib $HOME/lib114
----------------------------------------------------------

Extract new release Binaries & Start AlbyHub

tar -xvjf albyhub-Server-Linux-x86_64.tar.bz2

./
./lib/
./lib/libldk_node.so
./bin/
./bin/albyhub

systemctl start albyhub
----------------------------------------------------------------

Login and open new private channel
Navigate to http://localhost:9090
