Thanks - I'm taking a look at this.
For context, we removed this from Questing since we could not find any
references to it in software-properties-common or subiquity, and since
it appears to have not been updated since 2020 (and thus we believe it
was subsumed by equivalent functionality in other parts of the ubuntu-
drivers application, since it seems to be an outdated version of
UbuntuDrivers/detect.py and ./ubuntu-drivers).
It looks like there is still a lingering usage of it in here, though, in
DistUpgrade/DistUpgradeCache.py:
```
def checkForNvidia(self):
"""
this checks for nvidia hardware and checks what driver is needed
"""
logging.debug("nvidiaUpdate()")
# if the free drivers would give us a equally hard time, we would
# never be able to release
try:
from NvidiaDetector.nvidiadetector import NvidiaDetection
except (ImportError, SyntaxError) as e:
# SyntaxError is temporary until the port of NvidiaDetector to
# Python 3 is in the archive.
logging.error("NvidiaDetector can not be imported %s" % e)
return False
try:
# get new detection module and use the modalises files
# from within the release-upgrader
nv = NvidiaDetection(obsolete="./ubuntu-drivers-obsolete.pkgs")
#nv = NvidiaDetection()
# check if a binary driver is installed now
for oldDriver in nv.oldPackages:
if oldDriver in self and self[oldDriver].is_installed:
self.mark_remove(oldDriver, "old nvidia driver")
break
else:
logging.info("no old nvidia driver installed, installing no
new")
return False
# check which one to use
driver = nv.selectDriver()
logging.debug("nv.selectDriver() returned '%s'" % driver)
if not driver in self:
logging.warning("no '%s' found" % driver)
return False
if not (self[driver].marked_install or self[driver].marked_upgrade):
self[driver].mark_install()
logging.info("installing %s as suggested by NvidiaDetector" %
driver)
except Exception as e:
logging.error("NvidiaDetection returned a error: %s" % e)
return False
```
I'm taking a look to see whether this is something already modernized by
another part of the u-d-c source. If so, we'll update the u-r-u
package's invocation here - if not, we can revert the Questing version
of u-d-c to add the NvidiaDector back in.
stay tuned.
