Title:
apt update crashes with "KeyError: 'suite'" in cnf-update-db if index
compression is enabled
Status in command-not-found package in Ubuntu:
Confirmed
Bug description:
On all Ubuntu releases since at least 19.10, enabling compressed APT
package list storage with command-not-found installed leads to this
crash in the cnf-update-db hook called by apt update:
Traceback (most recent call last):
File "/usr/lib/cnf-update-db", line 26, in <module>
col.create(db)
File "/usr/lib/python3/dist-packages/CommandNotFound/db/creator.py", line 93, in create
self._fill_commands(con)
File "/usr/lib/python3/dist-packages/CommandNotFound/db/creator.py", line 127, in _fill_commands
self._parse_single_commands_file(con, fp)
File "/usr/lib/python3/dist-packages/CommandNotFound/db/creator.py", line 165, in _parse_single_commands_file
suite=tagf.section["suite"]
KeyError: 'suite'
(To enable compressed APT list storage, add Acquire::GzipIndexes
"true"; to an apt.conf fragment.)
This appears to be caused by apt downloading an lz4-compressed command
list for command-not-found and cnf-update-db passing the
/var/lib/apt/lists/*Commands-*.lz4 files to db/creator.py, which does
not know about the compression and attempts to parse them as plain
text.
