Lost access to berry314.girod.fi: wrong certificate.
Attempted to update but failed:


The following certs are not due for renewal yet:
  /etc/letsencrypt/live/berry314.girod.fi/fullchain.pem expires on 2024-01-11 (skipped)
No renewals were attempted.
...
letsencrypt> sudo openssl x509 -enddate -noout -in live/berry314.girod.fi/fullchain.pem
notAfter=Jan 11 02:42:16 2024 GMT

April 25

Noted that I renewed the cert on April 14:


letsencrypt> sudo openssl x509 -enddate -noout -in live/berry314.girod.fi/fullchain.pem
notAfter=Jul 13 19:24:21 2023 GMT
letsencrypt> sudo ls -l live/berry314.girod.fi/fullchain.pem
lrwxrwxrwx 1 root root 46 Apr 14 21:24 live/berry314.girod.fi/fullchain.pem -> ../../archive/berry314.girod.fi/fullchain5.pem

It was just that the VPN was not set!?
No, the wifi had also failed.
Le certificat a été renouvelé le 13 octobre...

February 13

Renewed the cert:


letsencrypt> sudo openssl x509 -enddate -noout -in live/berry314.girod.fi/fullchain.pem
notAfter=May 14 18:57:09 2023 GMT

Unlikely that the build would take place in a virtual machine running raspian on arm6, but missing some basic tools.
So... let's assume the tools are meant to run on the local host and produce files compatible with the arm environment.


objdir> ~/git/gcc/configure --host=armv6l-unknown-linux-gnueabihf
objdir> egrep '[A-Z][A-Z]*"\]="armv6l-unknown-linux-gnueabihf' config.status 
S["READELF"]="armv6l-unknown-linux-gnueabihf-readelf"
S["OTOOL"]="armv6l-unknown-linux-gnueabihf-otool"
S["OBJDUMP"]="armv6l-unknown-linux-gnueabihf-objdump"

S["LIPO"]="armv6l-unknown-linux-gnueabihf-lipo"
S["LD"]="armv6l-unknown-linux-gnueabihf-ld"
S["DSYMUTIL"]="armv6l-unknown-linux-gnueabihf-dsymutil"

S["AS"]="armv6l-unknown-linux-gnueabihf-as"
S["AR"]="armv6l-unknown-linux-gnueabihf-ar"

Quite a lot.
