bug xelatex after ubuntu update

I use ubuntu 20.4. After an update, i got several messages of error by xelatex like :

File biblatex.sty’ not found. ^^M`

No hyphenation patterns were loaded for `french'(polyglossia) I will use language=l@nohyphenation instead

It must not be a problem with the preamble because it worked perfecly fine before. The update has likely disturbed the program. Any idea how I can solve that ?
